You're sure that there's fuel getting to the injectors?

IIRC there are 3 grounds at the back of the motor - one on the passenger side head, one on the back of the block towards the top above the trans bellhousing, and one on the actual top surface of the block back by where the oil pressure sender and cam sensor are (the ones that are pictured above). Make sure you have all three connected. I think the one that goes to the rear of the passenger side head is the ground for the coil packs.

I think that the one on the back of the motor, went to a non-bell housing bolt?

I know it's getting fuel. The plugs are wet and the fuel pressure is up there!

Tootall, that first pic, the ground in that pic, does it have an allignment tab on the side of it there?

I'm thinking I missed a ground now.

If the grounds check out Ok, what about the crank and cam sensors, are they all plugged in? PCM connectors OK?

well, it's gotta be electrical then... can you get somebody with a fresh set of eyes to look it over? Sometimes that'll do it.

Another vote for checking the ground wires.

I broke off the one shown in Tootall's first picture when changing my transmission. I don't think it would even turn over with this one wire disconnected.

No kill switch. Plugs are wet, so fuel is there.

Need to check grounds.

Anyone got anything else they wanna throw out there?
