I'd really appreciate some help here, as I'm banging my head against a wall and have wasted a ton of time trying to figure this out.
Yesterday I warmed up my car in the garage. It started right up, idled for about 30 minutes until the fan kicked on, and then I shut it off. I tried to restart it a few hours later, and it wouldn't start.
It cranks great. Voltage is good. Fuel pressure (at test port in engine bay) is great. Spark plugs are firing, but plugs are dry. (It will run briefly when gas is put in plug hole)
So I figure the injectors aren't working. Why won't the injectors work?
The injector fuse is fine. The "main relay" seems to make contact when turning over, but I'm going to replace it tomorrow anyway. I have cleaned all 3 grounds that I can find in the engine bay. I've reconnected every sensor. The crankshaft sensor seems ok, as I can get the EGR valve to click when I hand crank the motor. I swapped cam position sensor.
I switched ECUs...and that didn't help.
I'd love to hear some new ideas?
