Another Gtr Not Starting

[bunno32gtr]

Yea ecu seems to be working. I actually tried to fire this morn will try play with the injectors now

[bunno32gtr]

Yea pulled the top off the ecu and found no burn marks. Had no smell either

[bunno32gtr]

I've now tried a new ecu and still won't fire. Sounds better now and sounds like it wants to fire but just can't for some reason

[bunno32gtr]

UPDATE.

It started last night with new ecu and a fully charged battery. But it took a while and a bit of gas and died of I didn't keep the revs up. Have a timing light and gonna check that tonight and also go right over the cooler piping again just incase I missed a vacuum leak.

Thanks everyone for your help so far

Did it low any black smoke or no smoke?

[bunno32gtr]

No smoke that I seen but it was pretty dark.

[bunno32gtr]

hi DVS i have just tested the car again a small amount of white smoke came out. i then tested with out the afms and run the same. checked my codes in the ecu and got 12 which is afm im guessing cause i unplugged them and also 21 which was ignition signal. any idea wat would cause it to throw that code.

[DVS JEZ]

Try and get a noid light or led test light to make sure the injectors are firing.

Did u fix the power feed to the injectors?

Is the fuel line from the fuel filter to the fuel rail getting hard when the pump is priming?

Try and restrict the return line from the rail to the fuel tank by squeezing it closed with soft pliers ie turtle jaws (plastic pliers).

Were u driving when the car stopped or it just wouldnt start?

Does it have fuel?

Does it definately have spark?

[bunno32gtr]

put noid light in number one injector and started light was coming on. i fixed the power feed with a new ecu. guessing injector drive was fried like you suggested. fuel line is getting hard. i was driving when it stopped was on the highway and it started misfiring and then died when i hit the clutch. definetly has spark tested every coil and plug. definetly has fuel aswell. thanks for all your help DVS i would be stuffed without ya.

this stuff is heart warming

nice to see the dialogue unfold

keep it coming guys

[DVS JEZ]

No worries man.

Just to be sure take the Fuel line off the rail and put it into a clear bottle then prime the pump so u can get a sample of the fuel, who knows it Might be full of water from a servo, if the fuel is ok and not contaminated put the line back on the rail and tighten.

Ok so u now have spark and fuel, chexk the timing of the cam belt and crank angle sensor thoroughly then its time for a compression and leak down test.

Interesting!

Have you tried a different ignitor?

Got to think If the car was runing and it backfired there a few things that cause that?

Excessie heat? (to lean)

Ping?

Unburnt fuel in the bore? (no spark in a cylinder)

Detanation?

From what you are saying it sounds ignition related tho

[bunno32gtr]

I will try and hunt down a different ignitor and test that. Not sure about it leaning out usually end up with black shit all over the back of my car after driving it for a week. Will look into the ignitor though and also yet the timing tonight

[Frosty]

Have you checked the cas also?

[bunno32gtr]

Yea mate I replaced the cas

[bunno32gtr]

hey guys checked the timing and got it back to position. Tool it for a drive jut to see if I had a bit of shot fuel in the bores when I took off it started blowing blue smoke and won't get positive pressure tested it when I got home and my rear turbo isn't sucking. Gonna start ripping it off now and will report on the state of it

[DVS JEZ]

Soo so far its been a mixture of issues,

Fried ecu , timing incorrect( was it cas timing or cam timing?)

A blown rear turbo? Which unfortunately will more then likely mean ceramic dust has entered the cylinders. But hopefully not.

Have u got the turbos off yet?

What turbos are u going to refit?

[bunno32gtr]

I'm thinking Nismo ones now. Was so happy it was running but took it down the street and now this. Devastated

[bunno32gtr]

Ok i have now replaced the turbo which was buggered found the rear wheel (or what was left of it) in the cat. Now will not start with out a few pumps of the pedal and sounds like a Subaru I drove it for a bit and got it warm still the same story.

[DVS JEZ]

Do a compression test just to check.

Check which cylinder is misfiring
