ok i was on last time and you guys told me to set my CAS back to factory.....i did that today and the car showed improvement ....i think before i set the timing i didnt get any smoke...now i got smoke coming from my exhaust and the car shakes and sounds like its going to start....but doesnt....=(
i got spark,,,, i got fuel...i reset my timing...i tried switching ecu's...i check wiring many many times...but no start...pleas help me on my SR!! i want to drive!!!
any feed back is great help please if u think its anything ...what ever you can think of to help please list!! thanks alot .....

pretty car that dont move!
hey man i just recently got my sr done bout a month ago, and i thought i checked everything and we took out the schimatic and volt meter tested everything, and she was cranking and wanted to go, so we took out the CAS ripped it apart and then realized the actual plug that goes into it was plugged on backwards, i have no idea how but it was so we took the clip off and manually rewired it so ground was to the right solenoid power supply to the right solenoid and so on, it wasnt sending a signal the ecu to tell her to fire, but we did it and she started right up first shot. So i dont no give it a try see what happens.

yo for somereason i think this might be the answer.....cause i was testing shit and when we were testing wires with the ground and you know pluggin each wire to see if the light comes on .....i stuck the tester into the crank angle sensor and the freakin fuel pump would go on.....so hit me back up and tell me exactly what you did to check on that...cause imma try to do it and c what
[email protected]!! thanks...and if this works man im gonna send you something....i been tryin to get my sr to work for about amonth now....its all painted and bodykit and suspensions and everything ready to go but it doesnt and its hard looking at it everyday knowin that i cant drive it!!!!!

sorry if this is wasting ur space, but how do u set the CAS to factory?

don't use test lights on sensor plugs. Really good way to kill your sensor/ecu/solenoid. The CAS once taken out is a bitch to put back in correctly. There are two dots that you have to line up. I forget if you have to offset one of them to the other, so that when you put them in, they will line up..... But you have to make sure you chain is on correctly first! ...then spin the shaft on the CAS and line up the dots, or offset them on either side of each other. Sorry, I forget the exact method. But one of those is the right way. It's just a simple process of elimination.

yo silver bullet jus to to PHASE2MOTORTREND.COM they have a sheet and information that you can follow to set it...you might think its kinda hard to do but very easy...the hardest part is taking the valve cover off and putting it back on!
but "90SR" i want to know how you did what you did to get your car running ...step by step aite thanks!!

make sure ur fuel lines are not switched up, sounds retarded but thats what i did...setting timing with valve cover removed is a cake walk, the fsm tells you how to do it exactly. removing the valve cover is NOT hard either, takes about 10 min, and your timing chain should not be off for any reason unless someone has seriously tampered with that motor, to check it rotate the crank till you see the exhaust cam(drivers side) key way(not the mating marks) is at 12 o clock at the same time the intake cam should be at 10 o clock. you should have two silver links on on each tooth with the mating marks. they say silver but really they are darker then the rest of the links. dont be fooled when you rotate the crank shaft and you dont see the silver links, if you dont see them then the cams are not in the right position so just turn the motor over one more time to tdc and you should see them then...there is also a gold link this one is on the timing mating mark of the crank shaft sprocket, there is NO WAY to check this mark that i can see with out having the front cover off the motor..i couldnt even see when i had my oil pans off. but like i said your timing chain should not have ever been moved and should be dead on. but in order to have your motor in correct time you must turn the motor over till its top dead center on first piston, with the silver links visible and key ways where i said before, then when you remove the CAS there is a mating mark on the main part the the CAS that does not rotate, on the part that does rotate there are two mating marks, you line up the front mark with the mating mark on the part that does not turn then once you push the cas into place it should slide in and click forward somewhat, you then rotate the cas clock ways about an 1/8" or so to where the second mating mark or the middle one is lined up with it...it is really hard to explain this with out pics. the fsm talks about the 2nd mating mark in the middle having yellow paint on it...mine didnt have any paint...go figure. once you have the valve cover off and start gettin into it you will see what im talking about and the fsm really really helps so you better download it...i hope i helped and didnt ramble on and make things confusing. good luck!

wow, i just relized that you are the same guy that got hugely flamed for bad grammer and ghetto lingo in ur other post, that was about 3 or 4 weeks ago...looks like you cleaned up ur grammer since then haha...those guys really ripped into you, dont know why they do that, its easier just to help.

hey scot your gay and yes i do need to get my silvy up so i can drive it what do you think im tryin to do here !!! winter is coming up and thats hibernating season for the orange 40!!
and bradman....yes i was the guy they ripped on i dont know why either but maybe if they would help me my car would be running now huh??its all good they do what they do and i do what i do thanks for the help buddie!!!
90sr where are ya!!!
yah dude all we did was pull the CAS out, took the cap off opened it up and found out it was fine, lots a little pieces so be carefull, then if you have it a voltmeter, take sum pins and alligator clips and put the pins in the plug and put the alligator clips on each pin, ground one a the clips, and jus see wat the voltage is of each wire runnin to the pins, theres voltage for almost everything on the sr20, i have a 200 page book telling me everything i need to know volts, measurements, grounds, everything around the perimeter and all the problem was the CAS and when your putting it back in BEFORE you pull it out take a flat head or something and make a mark where the screws are so if the timing is set you know where it was before you took it out, now when its back in and the wiring is right, turning it to the right the idle will speed up and turning it to the left it will die out, so jus keep it till its constant. Anymore questions dude just call me up if you want its 848 992 2680.

chris what im going to do first is my buddie has another crank angle....so imma switch and test that out to see what happens.....another thing i think i dint do is that when i took the CAS out i didnt set to TOP DEAD CENTER....i just pulled out the CAS and spun it till the dots where correct then i stuck it back in......or is that right???

set it to TDC then align the marks on the CAS. There's a "how to" on phase2motortrend you should follow.

Easiest way to tell if its TDC is stick an extention down the plug hole #1 cylinder and watch it raise all the way to the top when ur turning the crank. once its all the way up, look up ur intake and exhaust sprockets and they should be at 10 and 12 oclock position respectedly. Only thing i cant remember is, once you do this, is the timing needle by the pulley supposed to be lined up on the 2nd notch from the right side or left side???

ey thanks man that helps.....and your project looks like its coming along so good. luck...mine look like that at one time but much more ugly then that....and i cant figure out how to put up a pick like yours up on the post...i tried it and it just left the code and stuff out but o well...thanks though...i have to get my dam car runnin!!!

aight boys, top dead center is 2nd mark from left on crank pulley, there is no way it could be anything other then tdc unless ur pulley is not an sr pulley haha. you cant correctly set the timing on the cas with out the valve cover off. sounded like you tried to do it that way. if you do it the way i explained earlier which is exactly the way the fsm tells you, your car should be in good enough time to start. i havnt put a timing light on mine, but i lined up the marks and it starts drives and idles like a dream. i plan to get a light on it some time here in the next week. when fliprayzin240sx says sprockets at 10 and 12 o clock he means the key ways, not the match mark dots. they will be slightly off, more like 10 and 1 ish. the key ways are exactly at 10 on intake cam and 12 on exhaust, and the cam lobes on the first cylinder should be facing away from eachother.. tdc is not a rocket science...if u dont trust ur pulley pull the plug and take a peak. but ya, if u set the timing that way, and you know ur wiring is right, ur fuel lines arent switched up you have spark on all 4 cylinders then it should start and run fine...if its still not starting its time to swap out the cas in my opinion...i really dont know what else it could be. if you have spark then the igniter chip and coil packs are fine. and the idea of the plug being wired backwards seems outragous, but im not doubting that its possible. that would be a huge factory error and the harness would have had to be customized for it to work on the original car also im guessing. that would be way wierd if ur car had that problem too very doubtful...but thats also just my opinion.

ok bradman...that was alot of good and useful information...if my car should start cause of you...i am your slave for a weekk....!!! ive had my car done for about a month and its been sitting in the garage...i wanna drive it noww...so thanks for that and i will get right to it..ill tell you how it goes...thanks!!!
yah dude, just take out each individual coil pack, take out all the plugs and test them seperately put the plug in the coil and hold it to the block see if theres a lil lightning bolt when u crank the engine, make sure all 4 plugs are sparking, next, number 1 cylinder, alls i did was took a piece of regular size paper rolled it real tight and held it down on the cylinder and u have to manually turn the pulley its easier, or have someone do it, you watch the paper go up once it gets up to a point itll start going back down then you stop turning the pulley, then your at tdc, and 2nd notch thing it worked twice for me then it didnt work i dunno so i just did it my way, and then i explained to you how to test the CAS so do all that you dont even need to take the valve cover off just set the dots and slide it back in and it will set itself just try not to move it much when your sliding it back in. Um tighten the bolts back up make sure your fuel lines are going to the right spot, i had that messed up too, um make sure your fuel pump is primin, um other than that you should be good to go long as the wiring and all is correct. Let me know whats goin on man

ok guys!!! the reason for not starting was the CAS...and the car not being on TDC......today i took everyting off...set the car back to TDC...and then redid the CAS...then i started it couple times with the Crank angle sensor off...and fuel fuse off....then i plug the crank angle back in..with the fuel off..then i plug everything back in....and i started it once...not even thinking it was goin to start and bam!!!!!!!!!!!!!!!! it started!!! i was the happiest kid alive..........
but once it got started it ran for about 5 seconds then it died....but i was still happy cause after a month it started...and it was the timing....i started again and was hittin the gas to make it stay on and it feels like it should stay on but then afta 10 seconds of steady idling it would die slowing....why./????is the maf bad.....do i have a valve or air leak somewhere....somebody help me if you had the same problem.....
so it starts right away and runs if i stay on the gasss...but when i let go and let it idle it stays on for about 10 seconds then it dies........may b the timing is still off a lil....bad maf....air leak somewhere....umm iono what else could be the problem but i would like some help....
