What's the list of parts you have replaced new so far?

Could be fuel pump?  Check its pressure.

Thanks, Ill check those in the morning and report back.

Plug wires

I plan on testing Coils tomorrow and I've got a good ICM laying around. I also plan on pulling the uim and checking the vacuum lines. But first Ill check fuel pressure and compression. My SES light is not on.

There are two grounds for the ecm on the back of the motor. When I reassembled, I put both of those grounds on the same bolt. Would that be my problem?

no, a ground is a ground.  and just because the SES light isnt currently on, doesnt mean it doesnt have codes that are stored.

Problem Solved!!!    :icon_mrgreen:

I tested the car with the wastegate not connected and got plenty of boost.

So I removed the boostcontroller and took it apart, put it back together and now it works!

Get consistently 8psi.

Thanks Everybody for your Help!!

I think beecher is about 2.5 hours away.  We'll meet up sometime. I go to the 1/4mile in Morocco IN a couple times a year. You ever been there?
