venomstreetmachine · 06-25-2009, 03:20 AM

I have been working on my 90 supra Turbo for a year now.

I changed the head and gasket ! decided to upgrade the exhaust manifold and turbo.
I also installed a fuel pressure regulator....
I need help !
Got everything mounted the car turns over but wont start !

1, the intercooler piping gets really hot just cranking the engine over !
2,Fuel Pressure only builds up when cranking
3,The car will start half arsed when I spray starter fluid pops and backfires!

Im dying to get this car going can someone help me or give me a hint

Any codes? Have you checked the mechanical timing as well as your CPS alignment?

Yep, Timing is spot on ! But I will check it again !
I have great compression !

Would you happen to know what the fuel Pressure should be? and if the EFI system should pressure up when the ignition is turned on? or when I turn it over?
Thanks for any help !

Fuel pressure for the GTE is supposed to be 33-40 lbs with the key in the ON position without the engine running. There are different procedures of checking the fuel pressure at idle, here's a link...

I appreciate the help ! But whats happening is... when I turn on the key nothing happens, the dash lights up but no fuel pressure ! I only get pressure when i am cranking.

Have you checked the EFI fuse? Is the fuel pump getting power?
