hi all....

I have no idea now... hoping some1 can help me,

I have just finished my 100k service (everything their is ok it turns no problem)

Installed a GT3540 on the stock manifold with external wastegate

and a greddy style plenum....

it will turn like it wants to start but it wont fire.... it has fuel and spark.

it kinda feels like an earth or vacuum leak, but i can't find anything.

what else could it be???

Thanks in advance

Josh

lol I didn't know installing a GT3540 was a part of the 100,000km service?

Not sure about you problem though? Sorry.

Maybe IAC valve? What happens if you pump the throttle a little while starting?

So I'm asuming you did timing belt?

Timing marks could be off.

Nothing much... sounds like it wants to start but just doesn't go...

The GT35 is the most important part of the 100K service... LOL

No i don't think it would be, I triple checked everything when i put it back together....

just double checking man. by its got fuel...u mean injector pulse?

i installed a 3540 and a greddy plenum.

when i went to start it I HAD THE EXACT SAME PROBLEM

what u have to do is. reverse the fuel hoses. so switch the hoses coming from the fpr with the feed hose to the rail. so swap them around

i had that problem.

very easy to overlook. make sure the hose from the fuel filter goes to the inlet for the rail NOT to the fpr

symptons were....it would crank and crank, and want to start. but it wouldnt run.

I'll give it a go when i get hame from work... i'm pretty sure they are the wrong way around:)

the fuel line with the fuel filter should go to the rear of the motor, the return line should come out of the reg at the front rail..

the easiest way to distinguish these........

the fuel pressure reg is always the highest point of the fuel system as not to air lock the fuel rail. this is where your return line should go.

sounds like basic stuff i know but it never hurts to check the cooler piping again, i checked mine four times before i found the leak cause my engine to hunt.

Is the CAS mounted correctly? Does the exhaust cam still have the half-moon key that correctly aligns the CAS?

Got it going

Ended up being the fuel lines lol...

Now it's hard to get to idle properly been playing with the aac and the computer idle control and slowly getting their

Thanks heaps for all your help and being so quick guys,

haha yea i paid 400 for a mobile mechanic to tell me my fuel lines are reversed .

yer man mine was running rich too. but just run the stock ecu. it runs fine.

atleast for a little while.

shud be able to putt you to the tuners, install pfc or wateva and off u go.

btw enjoy the 3540. they freaking PULL!!!

Yeh i think i have it under control now... i'll finish the exhaust and diff then i'll put the Power FC in and get it tuned...

Cant wait to feel her kick now... going to be so much fun...
