New to Supra's had a few Q's

turbot11 · 10-19-2011, 11:23 PM

Ok back form the dead! It took months but he took it all apart, had the head planed (per the recommendations here and thankfully against the advice of his dipshit friend) put it all back together and has it running! My only gripe is he used an MLS gasket when a composite would have been in order but so far so good and no leaks. However he is having a few troubles with the car, from what I've been told it acts as if its hitting fuel cutout. I set the turbo up so that there is NO controller, no solenoid or anything between the boost/vacuum nipple and the wastegate. So maybe it hits 4-5 psi max, no way it makes nearly enough to trip any comptuer programmed shutdown. He says that when it does this the check engine light flashes and shuts off. He thinks it may be fuel related, Im not sure but I want to check a few things including fuel pressure. My questions are what is static pressure supposed to be? Where do you connect a pressure tester? How do you retrieve codes from this car, and where can I find a list of fault code discriptions? Is the fuel pressure adjustable with stock components? He says there appears to be a knob on what he says is the regulator on the rail that hes played with. Any ideas are greatly appreciated
Thanks in Advance

Oh goodie.... There's always someone who just KNOWS they're going to be the exception to the rule. The 7M wasn't smooth enough for a MLS NEW from the factory! Why do people think it somehow must've gotten both smoother and flatter after 20 YEARS or service?! Good luck with that one. ROFL. Maybe you'll get lucky, but you're really probably going to be screwed in a year or less.

See the MKIII FAQ section for a thread on diagnostic/error codes. The problem sounds like either a bad airflow meter or serious boost leak. I hope he didn't try to clean the AFM.

There is NOTHING on the stock fuel rail that is adjustable... The Fuel Pulsation Damper (FPD, looks like a second FPR with a plastic cover) has a screw which is preset at the factory or a certain response time and pressure but it isn't to be touched under any circumstances (it's even covered in certain Toyota publications)... Touch it and trash it is the jist of it (really there are worse things to screw up with but you'll never know what it should be set to or how to do it Toyota doesn't publish that info that I've ever found).

Yeah I was real disappointed when I head an MLS went on, especially after I STRESSED that a composite be used. I saw the damper on the end of the rail but he was stating this was towards the middle of the rail, it's been a while since I had my hands on the car and I dont remember what was there. Thanks for the tip Ilook there and see what I can find

Nah, there's nothing in the middle of the rail really.... The cold start injector is in the manifold beneath it...

Do you know which brand and which type of MLS was installed? (If you say HKS stopper, forgive my laughter... and start saving to replace it in a couple weeks.)
