Startig Issues R32 Gtr

[Zardos]

I have been have starting issues where when I start my car it takes about two goes before it will start.

This has only happen after I had a new fuel pump, 700cc injectors and adjustable cam gears fitted.

Is this something I can fix myself using the hand controller (PFC) or will I need to take the car back to where I got all the work/tune done?

At a guess, the fuel may be draining back to the tank while its switched off. Next time you start it try giving it plenty of time to prime the fuel system before you crank it and see if this makes any difference. Could be a check valve fault, or a split hose, or loose hose, really any number of things. However if it has only been doing it since the new parts were added i would look at them first Check you have good fuel pressure during pump operation and after the ignition is switched off. It should hold pressure for quite awhile.

Good luck,

I have an aftermarket adj fuel presser valve fitted with gauge and as soon as I turn it off the pressure drops to 0 really quickly.

Since Mine was modded, I have a second crank start, never fails to be the same, but the tuner can sort it if you tell them, but am ok with mine, I know it will start.

My bet is on the fuel system. If there were no changes made to the mapping in the computer its about the only thing that could cause that. If that gauge reads like a master gauge would (it should) then thats most likely going to be the problem. Just make sure it does that even after you just switch the ignition on and the pump primes then you turn it off without starting..
