So I have gotten it started a couple times and gotten it to idle, but very rarely. When it does start and idle it idles smooth though. Give it any throttle and it dies instantly.

I suspected bad gas, so I drained the tank, put 3 fresh gallons of 91 in it along with a bottle of fuel injector cleaner. No dice.

Hooked up a fuel pressure tester to the rail, about 55psi priming and jumping between 55 and 65psi while cranking. Seems pretty good to me.

This thing is pissing me off now, these are supposed to be easy.

Edit: and coil wiring is good.

Did you get your problem figured out? I'm having the same issue. I have not tried the starting fluid spray yet but that is my next option. My car ran fine right after I completed my conversion last week but now it just stumbles and dies while trying to start it.

Yes, SpareECM had loaded a corrupt file on the ECU I bought from them.
