Roomate Borrowed Car now its dead

[overboostedlebaron]

BREAKTHROUGH SORTA!!! OK today i said **** it and bought some either. i sprayed that **** into the intake and it started like it should then died after the either burned up. i plled my fuel line and attached a bigger hose onto it to see if my pump was pumping when the car was on and yep! but its still not getting any.. ecu is still a bitch and i dont have a niode light. before i rip the injectors out which is a fuckin bitch any other suggestions?

PS. I HEARD BOOST FOR THE FIRST TIME IN DAYS WOOHOO!!!

Measure for +12V at the injectors. That will tell you if it's missing power or the signal from the ECU.

[DrMango]

+1 and its sounding very much like its just injectors. I dont know much about FPRs but could that be the issue at all?

also there is an inline fuse around the injector sub harness maybe take a test light and check it?

[overboostedlebaron]

well over a week since the no start and still no results. its 17degrees outside today so i will wrench on it some more. the car will start and idle like it was brand new when feed it either it sounds perfect but then the either runs out and the car dies. what else could it be its driving me crazy!!!!!!!!!!

[DrMango]

almost has to be fuel related. Can be FPR and injectors if you have fuel getting to the rail. Has to be one of those 2 things. Your at the point now where you have to switch injectors out with others and see if she runs. otherwise its gotta be the FPR i would say. Sucks but you have no choice but to change out the injectors, even if you think its not them. I bet it is

well its obviously not getting any fuel so if there is fuel at the rail it must be injectors.
take the vaccum hose off from the fpr and plug both ends and try starting it this can mean th fpr is bad.
i think your inline fuse to the injector went becuase it is uncommon for all injectors to die at once just like that.

also check that tps is set right.

Intermittent stalling and not starting can be symptoms of a faulty ignition module. It takes a while to cool down. Usually engine runs good for 10 minutes, then stalls and won't start for another 10 minutes or so.

Injectors can be checked by pulling CAS off, turn ignition to 3 and turn CAS. If injectors click, they are working and getting signal from injector drivers on ECU. You'll need to reset ECU, as get CAS error code. Also need to reset base ignition timing with timing light after refitting CAS, unless you mark the exact position of CAS before removal.

FPR can be checked by unplugging vacuum hose to FPR while engine is running. If engine stumbles, engine is running richer, which is normal. It pays to have a fuelpressure gauge plumbed in between fuel filter, fuelrail to check against factory recommended fuel pressure.

Should be -

Before starting engine, but fuelpump is primed = 42.6psi

While engine is at idle with vacuum hose to stock FPR connected = 35.5psi

With vacuum hose removed while engines is idling = 42.6psi

TY Skym, as always come to the rescue!

anyone want to buy a skyline? **** well i gotta wait till next spring i guess( i have none of those tools to do the tests skym said. im ****** i am seriously going to start abusing this car doesn't make sence

[Skym]

From what I have read in this thread, it sounds like a faulty fuelpump or ignition module.

Nissan dealership can do the fuel pressure testing, use timing light to reset CAS, but it will cost. Or one of those mobile mechanics (if you have them in Canada) should have the equipment if you have trouble moving car.

I think you do have mobile mechanics in Canada -

CAS does 2 things, fuel injector timing, ignition timing. It has little slots on edge of disc inside CAS for ignition timing and bigger slash like slots on inside of disc for injector timing.

[DrMango]

it makes a lot of sense. You cant expect a 20 year old car not to have problems. If you werent ready to have small issues like this then a skyline really isnt for you. EVERY skyline will have issues like this. KMs dont mean anything, its how old the car is. You dont need tools for anything. Its either your FPR(easy free test) test it like he said. Remove vac hose and see how engine responds. Or its the inline fuse to the injector. once again a free check and its either a yes or a no. next is the ignitor pack. once again free test. Put out a call in your region for someone with a RB20 to let you try their ignitor pack. People as you can see want to help you, and someone WILL come through with a ignitor pack for you to try.

free test and takes NO tools you dont have. Mark your CAS with a marker and your good!

Fix your car. We have all been telling you how to do this for like 4 days now. I will help you however i can, so will the rest of GTRC. We are good comunity and i know someone in your area will have the ability to help you!

If engine has done over 100,000km, it's common for fuelpump, auxilaries on engine to fail, which need replacing or rebuilding (routine maintenance). Fuelpump shoud be changed out every 100,000km and fuelfilter changed every 20,000km or less if the fuel you use is bad. Running fueltank low most of the time is one way to make fuelpump fail earlier, as fuel running through internal fuelpump, cools fuelpump.

I was shown by auto sparky that tapping ignition module with rubber hammer while engine is running is one way to see if ignition module is causing problems. The other way, via I think was Oscillioscope. But on my car, cracked the black coloured casing on ignition module (weakened plastic due to engine bay heat), so be careful and do it lightly.

Supposedly same tapping trick can be used to check for faulty MAF's.

[Brendan]

Have you measured for voltage at the injectors yet? I'm betting there isn't any voltage and this is an easy fix.

[love_boost]

if the ignition module was shot he would not have any spark or a very weak spark?

like i said check the inline fuse to injectors.

also you can pull the spark plugs out, if they are wet you arent getting spark.

and as mentioned the FPR, alo check for leak in FPR hose. have you pulled the fuel line off after the filter?
