The coil packs have power and the injectors are firing but the car just cranks and cranks and wont start. It acts like it wants to but wont. It ran a while back and I even had it going half *** last night. What should I check next? It has fuel pressure. It barely even fires on starter fluid, it use to crank up with it. Only thing I can think if is maybe the harness ground came off, I just thought about that.

I would pull out a spark plug and see what it looks like.

The plugs were pure black. I swapped them out and she fired right up! Thanks! I'll post a pic of how bad they were in a second.

The car is still kind of a pain in the *** to start and requires starter fluid. But after it's running a little bit it cranks up fine. What's causing this?

How old is your gas? try replacing the spark plug wires.

Nice! Can you tell us more about your setup? Your tune could be way off or one of your sensors could be bad.

Get it on a scanner and have it checked out... any Codes ? O2, A/F ratio and other reading of the sensors.

Check all of the sensor connectors (Cam, Cranks, etc), Check for a vacuum leak, weak coil, bad injector, etc

What fuel pressure is at the rail ?

Just a few things to check, Good luck.
