check the main fuse.... i had the same problem last week and the car just kept turning and yeah, check for spark

 

DO NOT ATF YOUR BRAND NEW MOTOR. ATF is what you use for OLD motors. TRUST ME. I normally use a ton of vasoline/oil to assembly my motors(especially this last one) and they always start on the first try.



Like everybody said. only 2 things you need...spark and fuel.

 

yeah definitely no atf...



make sure she's not flooding, crank iwth the plugs out and see if theres any mist



although if you've been cranking a bunch and no fire, it should be flooded. If you don't find mist when you pull the plugs and crank, your injectors are not injecting fuel IMO.



confirm fuel

confirm spark

confirm roughly correct timing

confirm compression (make sure it's not flooded...)

confirm air (no rags or animals in intake..)

with all of the above present, you have a running motor.



if you require more lube in the chambers because fuel has washed all the oil away, use a bit of MMO leave the ATF on the shelf.

 

Yeah... I'm getting a little frustrated. Not sure what the hell is up. I have fuel. But it's not making pressure at the regulator. At least the regulator isn't showing any on the gauge. I know there's pressure because I took off the empty port on one side of the reg and got wet... literally



I don't think the injectors are firing. I'm running a wide open DP and I see no signs of fuel. Don't even smell it.. Not sure if it's related to the regulator or not.. I'm not even sure if there is spark but at this point I guess it really doesn't matter as there isn't fuel to burn anyway.



I KNOW the pumps and lines are right. 2 Walboro 255s at 12V is hard to miss.. I just don't get what the hell is going on at the regulator.. To be honest, I'm not sure WHY the injectors wouldn't be firing... UNLESS it's ECU related. Like I said, I know **** about the PFC, only that there are base maps (I checked) in it.. I looked at the ignition maps and they seem reasonable. (Compared them to a map I found here). Nothing that would render the car un startable..



Would the 1680's have something to do with it? I haven't hooked up the datalogit yet, so the secondaries are incorrect.



This sucks because there is a ~800HP GT40 Supra at my shop right now that I could.... buy..

 

Regulator should be showing pressure. You went into the rails and out to the regulator side port?



Have you got a multimeter? Check for voltage at your injectors.



Secondaries shouldn't be firing while cranking anyway.

 

Justin,

I dont think the secondaries would have anything to do with it at idle as they wouldnt be on...but it could possibly be one of those codes where the ECU freaks out and wont let anything happen. The Regulator seems fishy...is there anyway to take it off and test it (run air through it with a compressor and see if it registers/comes out the other side)?

 

if the pumps are running, and you don't see pressure, and your FPR is plumbed properly, I'm going to have to say your fuel pumps are wired wrong, reversed polarity.... they're trying to pump into the tank rather than out (it's just a dc motor..)

 

Not sure what you're asking (or that you are sure what I meant LOL)



Goes Feed to Primary, primary to secondary, secondary to port on the right of the regulator, then out the bottom to the tank. I opened up the spare port on the left side of the regulator and it was full of fuel.



I gotta take a break now, as I popped the big inline fuse to the battery (Cheapo)

 

Double checked them. Positive they are right.



However, if they were wrong.... Fuel would still travel to the rails right? It's showing on both sides of the regulator..

 

Did you adjust the FPR to allow some pressure? it might be all the way open or something?



Did you make any adjustments to it?
