I have an 87 Supra Turbo with a no start issue. There is quite a story behind this car. It has been to 4 different shops, the engine was rebuilt by one shop that didnt finish the install, a couple other shops tried to get it all back together. It came to me and I got it all back together, got it running, the fuel pump needed to be replaced and the tank had to be drained and rinsed because the fuel in it had crystallized and varnished. We put in a walbro 255, which gave us too high of fuel pressure, and we did the return line mod to help that issue.

It ran well for awhile, but would stall out during driving, started running rough, and now just wont start. There are no codes, everything is put together correctly, we have spark, fuel pressure, injector pulse, timing is correct, no boost leaks, everything is peachy... except that it doesn't run. It will crank and sputter a little like it wants to start, but nothing. The MAF tested a bit out of range, so we replaced it with a NEW unit, no change. With the MAF unplugged it still cranks and sputters the same.

We have been though SO much with this car that it is just very frustrating. Any help is appreciated.
Thanks

Check engine error codes, make sure the ECU ground in the engine bay is nice and snug, double and triple check all of the connectors in the engine bay to make sure they are snugly attached to each other, verify the plug wires and injector wires are in the correct order.
