[Evolutionz]

my recently acquired 240 is doing some weird shit.


Ive been converting it to a drift car, took out the seats etc.

I went to crank it up the other day, dead... just tick tick tick.

new battery and now it runs rough, like its missing an engine mount (it isnt)

slowly slowly decreasing in rpms til it finally dies (over a 5 minute period or so.)

I had a vacuum leak in the cold air intake, fixed it, but still the same. when I get it up in rpms it runs so so. it bogs on occasion, til finally it doesnt want to go anymore.

the cars new to me, everything looks okay, anything I can try? alternator maybe?

[bookoo]

Check timing...had a ka do that to me the dizzy was turned all the way to retarded and wouldn't do anything but bog..check for more vac leaks...but the alt, start the car, then unhook the battery and see if it dies if so then of corse alt is bad. Otherwise look for more vac leaks...get some brake cleaner and spray it down and see what happens.

Also is the idle roaming..?


Iac valve if so.

[Evolutionz]

unhook which part of battery? positive?

idle doesnt really roam, it just slowly decreases in short jumpy increments.

[Evolutionz]

unhooked negative... car didnt change at all.

does your motor shake violently like its possessed by satan himself?

[Evolutionz]

does your motor shake violently like its possessed by satan himself?

Yes! Extremely bad

[Evolutionz]

update, just got home, car cranks sounds like its misfiring and wont turnover. exhaust makes potato gun noises. no bueno.

ive checked nearly all lines, nothing is different.

[94spitfire91]

Spark plug wires in the right order? spark plugs and or wires may not be working properly. And if you hear a tick noise from your starter your starter is bad. Every starter has its solenoid and when it loses the ability to get power it makes that noise.

[Evolutionz]

the motor is turning, starter is good. should I just check plugs? like wtfff

[Evolutionz]

I hear a whining noise when the key is on, doesnt go away. mean anything? it sounds like it wants to start, but no bueno.

also, extremely low oil... that cause it?

[Evolutionz]

now the car for sure wont start, it rocks really really hard and wont get up past a 100 or so rpms. every so often it gets close to 500 and tries to officially start, then bogs down. there is still potato gun noises from the exhaust.

someone help!

[driftxninja]

could be fuel injectors.

check that all your injectors are firing. make sure that your fuel pump is priming and working correctly. make sure you are getting spark and that your wires are dry.

ive had a similar problem with a previous 240 where i would be driving and one cylinder would randomly stop firing and the motor shakes horribly. it was the fuel injector stopped firing so the cylinder wasn't going.

so also make sure your spark plugs are in the correct order.

[driftxninja]

you could have jumped timing also which is why it won't start now

[ericcastro]

first thing, make sure to get some oil in it right away !!

After that, do your spark plugs, car, and rotor.

Then go to auto zone and borrow the timing gun and buy some starter fluid.

try to get the engine started so you can check the timing.
(if not, no worries)

try and have someone turn the engine over for you and spray the starter fluid around different areas on the hoses, intake. If the idle picks up, you have a crack in the hose or intake.

also wouldnt hurt to take the fuel line out on the engine side, put it in a empty water bottle and try and turn the car over. is fuel going into the bottle?


where does this whine noise come from.

okay, on occasion of me manually trying to crank it, using the starter, it will sit pretty at 400 rpms for a few seconds once I stop, then fallonface...

just changed oil to full synthetic sexy ass pennzoil. spark plugs are on the counter, ran out of daylight. there is a tad bit oil in cylinder 3 from when I just redid the guide gaskets for the valve cover, the previous one was cracked and leaking... I dont think thats it. Im hoping it may be an injector, im scared its timing related.

I just read this http://zilvia.net/f/tech-talk/384511-sr20det-wont-start-locks-up-feels-like-2.html

and it seems like thats it. from what people have said, I think mine will be fuel related. the battery died super hard recently, and this is all derived from that, new battery, now running rough and now even worse, sounds like injector took a shit. are these expensive? should I upgrade? direct OEM? just curious.

When its light out Ill have more answers.

[Evolutionz]

just got to work on it, pulled valve cover to look for weird shit, looks fine I suppose.

went to change the plugs, the second one from the front is stuck, I mean, Im a strong guy, and it clicks and wont budge, tried several different wrenches. da fuck... leave it and move on or what?

[!Zar!]

Maybe you need to reinstall your interior.

[Evolutionz]

changed the three plugs I could, now its starts and runs, but not good, still kinda like its been possessed by satan. and when I give it gas it gets all retard.

Im thinking this is fuel, or hoping so, having hard time getting the rail off, I have to run to work and will be back at 6 to finish getting injectors out to see if one is faulty.

if not what else could this be?

[ericcastro]

Get some pb blaster or some liquid wrench and keep drenching that plug. dont crank on it to hard, or it will break in the head or strip out the threads.

Soak it for an hour, give it a couple tries to jar it loose, not long pushes. If it doesnt give, keep soaking it.

You could tap the socket with a hammer a few times to in an attempt to jar/vibrate the plug out of those threads.

[Evolutionz]

Ive got wetness all around my fuel rail... Ill be taking it off in the morning to investigate further. but its got spray all over the inside of my engine bay, Im just now noticing it I think

[Evolutionz]

also! it runs rough, getting lower in rpms til its at retard shaky idle. likes its missing or something, someone post up a firing order please, mine is just 1,2,3,4 all the way around on the distributor cap. maybe I went retard and messed stuff up.

if I keep it at 2K with my foot it wont fluctuate, it sits pretty. but idles like shit. and there is a whining noise when my keys on but not turning from Id like to say passenger side, in the engine bay towards the bottom, weird.

[driftxninja]

firing order is 1, 2 , 4, 3 bro

[driftxninja]

going clockwise.

[Evolutionz]

firing order is right, My car now starts up and runs fine for a few seconds. then it bogs out, its not from the start anymore. MAF? something like that? orrr what

[mattack69]

From the last few threads youve commented on, I can tell you are helping all these help threads out.

so sincerely, go fuck yourself.

This is my daily, if you cant help, shove off.

Im getting a buddy that has literally 20 240s to come help me figure it out, he thinks its an injector or the Maf. we'll see

[!Zar!]

20 240's?

Why the fuck...


Oh wait, I just noticed.

[MajorLiquidGaming]

check the maf....

[pandaroo]

you said when you turn it over it makes potato gun noises which leads me to believe that your timing chain had a big jump and the valves opening at completely the wrong time.

[Swifty]

Fuel pump might weak had the same problem with the exhaust sound!
once i changed the pump it was all good.

Just throwing some ideas out to you.

I was fucking with the spark plugs in the wrong order, now that they are in proper order, im simply back to me original running rough problem, the car runs, just not well. It runs fine for the first 6 seconds, then goes tits over kettle.

[Evolutionz]

20 240's?

Why the fuck...


Oh wait, I just noticed.
http://wwp.greenwichmeantime.com/images/usa/florida.jpg

I sincerely lol'd very very fucking hard.

[Evolutionz]

I checked my ecu for error codes, its the first time ive ever done it.

I fucked it up somehow and didnt count the first time and now I just get the 55 code, Ive even cranked it up until it dies. someone give me a how to tutorial and maybe get this some help.

It will idle vicariously around 500 rpms until I give it gas, at that point it bogs out. itll surge and run on its own though.

this sound like a maf?

[Evolutionz]

alright.

I have a small leak from my valve cover that Im about to handle. BUT I unplugged maf and it got worse and nearly stalled, so I dont think thats the issue. ideas?

[Evolutionz]

unplugged 3 spark plug wire, no change. smells like gas a little too. all new SP's, this mean its a wire? or maybe a rotor?

[ericcastro]

are your spark plugs getting spark?

do you know how to test em?


Get your car idling,

take the 1st plug cap/wire off the spark plug, hold it close to the valve cover, right up against it, and you should see the spark jumping between the end of the wire and the valve cover.

put wire back on plug.

do this to all of them.
they should all create spark.

If some of them dont, you arent getting spark to those spark plugs and it would be an old cap and rotor, or crap wires.

replace cap and rotor first, since they are cheapest.


air leaks in the intake can totally screw everyhting up too, so fix that up.

[Evolutionz]

Alright. Spark plug wires have been tested and all make spark. all evenly as well. Not that. but note that the back two spark plug wires being pulled makes the motor run better. flooding? I noticed that it looks like the injectors are paired off on the rail, so maybe one or even both of the back injectors on that rail are fucked? hmm. Ill have to try pulling the injectors to see whats going on, im running out of things to check, anyone?

[Evolutionz]

Im on the verge of calling this the beginning of my LM7 swap. how much would I get for a KA and two trannys at a junkyard or scrap yard?

[driftxninja]

so did you change the fuel injector like i forementioned? same shit happened to mine... since everything is getting spark it leads me to believe its the 3rd fuel injector...

[Evolutionz]

its been a week or two since ive been near a computer, so im bumping this back up with an update.

It hasnt been cranked for a few weeks obviously, I cranked it up and the first time it ran perfect, until I hit the throttle and it bogged out and started shaking again at low RPMS.

I kept playing with the injector wires, like unplugging them one at a time, the third or fourth one would make it run horrid when unplugged, but then I plugged it back in and it ran a little bit higher in rpms than normal idle, but was solid, no shakes, then returned back to earlier problems.

throwing codes 34 and 12.

Help me before I burn this bitch down.

[mewantkouki]

34 is the knock sensor code, and 12 is a mass air flow sensor code. That explains your shitty idle and inability to rev the car properly. I'm willing to bet your car is acting up simply because it doesn't want to be a drift car. Think hunger strike.

[Evolutionz]

lmao, this is plausible, so what seems to be my problem? mAF?
