Problem solved, can close thread.

Re-did the timing, took out cas, adjusted it, and bam!

[nismoman]

1?
2 ?
3 ?
4 oil pressure sensor
5 knock sensor under the intake Mani on the block
6 Maybe plugs into knock sensor sub- harness near iacv plug on intake Mani
7 thats no vacuum line, looks like a throttle body coolant line and the pipe it connects to is right there

[roadster6909]

# 6 plugged into the alternator
#7 i didnt even realize that lol..
#3 plugged into a plug right under fuse box
#4 do you have a pic of where this is also?
#5 do you have a picture of it? so i can find exactly where to plug it in?

Lots of thanks for sharing your wisdom :)

[240ND]

edit: bunch of wrong guesses! lol glad you figured it out!

[roadster6909]

Took off the intake mani because a bunch of hoses wheren't connected, and to see if i can find what he was talking about.. i cant really find the oil sensor or that knock sensor urgg...

[nismoman]

The oil pressure sensor is right beside the oil filter. The knock sensor is impossible to see from up top and hard to see from underneath. If its there you should see it eith the manifold off though. Have you downloaded the FSM? It has diagrams for the sensor locations

[roadster6909]

I tried starting it, but it didnt turn over, or make any ticking noises, read above.. i edited

[nismoman]

Wires 1 and 2 probably aren't needed. Look like plugs the go to the SR boost valve/bpt that usually mount on the strut tower with the igniter chip.

Does the fuel pump prime when you turn the key on?
Do you have both wires on the starter and is the voltage to it?

[roadster6909]

The fuel pump is on the side of intake mani right? Because i took that off and took all the fuel out of it so i can unbolt the intake and get them wires in beneath it. How would i know if it primes? Im not the greatest at this, and am learning.. Im not sure if the starter has voltage to it, it doesnt make the ticking noise so im guessing it doesnt but ill make sure tomorow, ill use the meter.

tonight i'm going to have a few, releive the stress and be ready for tmrw.

[cardoza]

To check if the fuel pump is priming turn your key to the ON position and listen for a high pitched noise. The fuel pump is located in the gas tank under the trunk and is easily heard when the key is in that position.

[Zach-sr]

Are you getting power to the starter?

Maybe your lower harness.

[iceman26xx]

was your car originally an automatic if so I heard one of the plugs near the fuse box with two prongs has to be looped think its the automatic park

[HS13KLS]

so much work

You are trying to be a post whore. The last thread you posted on was from 2007.


Anyways with the thread..

I think that #2 wire next to the drivers side plugs into your power steering idler thing. (you dont need it)
have you checked your 75 apt ALT fuse?

Check your grounds again and look at your ignitor.
Did you recently swap this motor or did you buy it like this.. or whats up?

[roadster6909]

The engine came out of this 240 for a rebuild. It was up and running, so this harness was in it previously.. meaning their isnt alot of work, but that something somewhere isnt plugged correctly or something. I'll get on it, check it out and come back with stats within a few hours.

[roadster6909]

Okay, i uploaded pictures, starter seems to be plugged in along with the rest of the harness. All i get is a faint tick from somewhere in the engine bay, but i think thats coming from where that first picture is located..

Found two unplugged tubes, wonder if thats my problem? Where would they go?.. Thanks!

Merry xmas eve!

[nismoman]

Hook those two hoses together, goes to the heater core. Did you bolt up the main engine ground to the block? And did you ever check the fuel pump?

[roadster6909]

I didn't hear any noises, just a click. How do i know which ground you are talking about? Is it the big thick yellow/ black stripped ground that is connected to the engine bay? I checked the starter wires and it has voltage to it.. the starter isnt starting.. not making any noises just a single click every time i try to turn the key.

Does the ground wire you are talking about look exactly like this? Mines black/ yellow though, and if so, where on the block does it bolt up? One side is bolted in the bay by my fuse box.http://i52.tinypic.com/futb1d.jpg

[nismoman]

Yes it's black and yellow
It usually goes from the battery tray to the intake manifold.
You can see it in this thread---> DIY, SR20DET Redtop IACV removal. (pic heavy) : SR20DET Forum (rear-drive) (http://forums.nicoclub.com/diy-sr20det-redtop-iacv-removal-pic-heavy-t369842.html)

[roadster6909]

Do you think the locations of the grounds could cause this problem? I know this is a LOL situation but i bolted it from the tray, to the bay... And this is another lol.. http://i54.tinypic.com/24ec9d4.jpg
Does the one on the valve cover need to be bolted onto the frame? Theirs a nut behind it on the frame.. also

I also have a ground that comes out of the lower wiring harness, its pretty close to the battery tray, i bolted it to the intake manifold, but i was wondering if that needs to be on the engine bay? This is where i bolted it to.. where the bracket is supposed to be. on the right side of the hose. http://i56.tinypic.com/1z3ntck.jpg

Also their is a ground that comes with the coil pack.. i bolted that onto the valve cover.. does it need to be on the frame?http://i56.tinypic.com/mw7d02.jpg

I cant think of any other grounds..

[nismoman]

Top one hooks to a bolt on the intake manifold or back side of the head. Bottom one bolts to the firewall. middle one doesn't belong there but probably is ok. They pretty much all attach to the intake manifold or firewall

[roadster6909]

The first two sentances refer to the first picture right? I thought that ground wire belongs their?? And i should bolt on the coilpack ground wire to mani?

[roadster6909]

Updated- got her to crank, but doesn't start.

[nismoman]

GOT HER TO CRANK!
Okay, so with the much appreciated help of nismo, i've got her to crank.
It was the main engine ground wire, located in the wrong place, and a few other grounds.
I cranked her around 3 times, around 5-10 seconds each time so oil pressure can build up (This engine was just rebuilt)

Now however, my problem is im guessing fuel. She doesnt start up.
I took the fuel pump off, dumped the gas that was in it, so i think it got air in the pump or something..
The gas is around 5 months old, and has fuel injector cleaner in it- alittle bit of it.
I would get fresh gas but i'm not exactly sure how i would get the gas out.. this is an sr20 powered engine, 1991 s13 chassis.
I wouldn't worry about air in it it, will push all the air through the system and back out. Check if there is power at the pump, if you haven't already. Don't worry too much about the gas either. Get it running, then top it off with fresh gas.

[roadster6909]

Where exactly do i check for power? In the trunk?
Maybe you can tell me in one of these pics..

[Motoskin]

make sure you don't have the fuel lines put on backwards.. mines wouldn't fire because i had mines backwords... fpr should be connected to return line!

[roadster6909]

Oops i was talking about the fuel filter, i took it off and dumped all the fuel from it, i didn't touch the fuel pump if that helps at all.. i just disconected the line that goes to intake mani from fuel filter and it is still dry.. it should have pumped up fuel already, where xactly should i check for power?.. and all my lines seem to be in the right places.

[nismoman]

make sure you don't have the fuel lines put on backwards.. mines wouldn't fire because i had mines backwords... fpr should be connected to return line!

Yeah this, the filter goes on the line closer to the firewall, return line on the end of the rail.
The link you posted has a pic of the fuel pump location. There are two cover plates. The small one covers the wiring connector. Check for 12v there do you have the service manual downloaded? It has all the locations of these things and what wires to check for voltage

[roadster6909]

I do but i can't really read the diagrams and i'm not home most of the times but i do have pics with me,

Which cover plates do you speak of?

[nismoman]

Oh my bad the plates are in the trunk.

[jvega]

i had a similar problem with mine. turned out to be the whole engine wiring harness. got myself a new one and started right up.

[roadster6909]

The fuel pump now primes, i hear the loud humming. I left the fuel filter line off accidently from intake mani and it shot out fuel, put it on, cranked it over twice, felt like it was bogging when i pressed the gas, but it didnt fire up. What shall i do now?

[roadster6909]

How do i check if i have spark? I searched a bit and they said to use ohm readers and all this stuff, couldnt i just unscrew a spark plug plug it into coil and put it against metal?

I have a thing that checks if their is power, looks like a pen, and it lights up if their is, do i just put that in the coil?

It's getting fuel so now i'm stuck as to what i should do. When it cranks and you press the gas, you hear like a pop/ bog once in a while, thats all i get.

[4-20sx]

worht a shot. but i remember i had a simliar problem. it was cranking but not starting. i had the fuel lines crossed. after i switched them. the sound of my engine was music to my ears lol =)

[roadster6909]

It is getting spark, and fuel, which fuel lines do you speak of?..Maybe i plugged something in the wrong place

[nismoman]

i looked at the pics of the fuel lines and they look good to me, hooked up exactly like mine. try to crank it without touching the gas, if you can get it to at least run for a minute you can check the codes at the ecu

[roadster6909]

I tried using starting fluid, and it didnt do anything, i just got a louder pop than normal

[4-20sx]

hmm. idk

so its cranking but not starting?

fuel or spark.?
