R33 Gtr Wont Start Help!

[MYP16]

hey all,

i have just bought an R33 GTR that has been sitting around for a few years.

done compression tests before bringing it home. all came back great.

i got it home and cleaned fuel tank, gave it fresh tank of fuel, new spark plugs, new fuel filter etc.

i borrowed an injector test light, i have got injector pulse. i cleaned the injectors and they spray perfectly and pulsate fine.

the spark is poor in my opinion. it has splitfire coils,

it cranks and turnsover fine but will not fire and start.

does anyone have any ideas?

iv also tried new battery etc.

thanks in advance for anyones tech help.

Have you checked the ignition timing with a timing light?? Ignitor or cam angle sensor could be faulty???

Is it running factory ecu or aftermarket??

[MYP16]

naa i havent

i tried a new crank angle sensor today, i tried another ignitor today aswell.

it has a mines ecu.

I had a similar issue.

Check to see if you can find any wires that look like they have made contact.

Mine shorted out on the power steering tank.

Failing that get it to a Auto sparky.

The ignitors are a common problem but I have only replaced 1 in the year I have had my GTR.

If its the CAS sensor you can just unplug the old 1 and plug in the new 1.... disconnect the coil pack whilst you do it and just turn you should hear the injectors ticking.

Try that and the Ignitor then start looking for a Auto sparky.

EFI got mine all sorted and wired up my new Wolf V500 Ecu.

Pull out 1 of the 6 coils and spark plug, rest it on the cam cover and tell someone to crank the car, see if there is any spark. If there is, replace and undo one of the fuel lines and see if there is fuel coming out when you crank it, if so replace. Then unplug both AFMs and try start the car see if that works.

Sounds exactly like an issue i had long time ago...

All the electronics/crank/spark/injectors fine etc just wouldnt start...

Booked my mechanic to come by my house and try and fixit and pay a/h's fees

Eventually found out i had mixed the fuel lines up... (Very common mistake)

Had the feed from pump going to the bottom of the reg and the return going to the rail...

Oops...

No Fuel = No Combustion...

Swapped em over & cancelled the mechanic home visit...

***simple test for this is spraying abit of degreaser in your plenum, if it starts or fires up then you know its a fuel supply issue...

You can start a car with a few coilpacks or afms disconnected, or a seized injector or 2, it'll still turn over... Itll just be rough/hunting, wont idle correctly and I do not advise driving it like so...***

Lesson...

Check every last thing you can yourself before handing over hard earned cash...
