No spark and i can only get 5V at the coil.

Did you do the "grounding wire" test on the ECU? See the post above I made. If it sparks grounding the one distributor wire, it's not the ECU. Normally auto stores will NOT take back "tried out" electrics.

EDIT Why, in your photo above, does it "appear" that there is a spark present?

I haven't done the grounding wire test yet. The picture above I snapped while touching the grounding cable to show that it did in fact fire when grounded like you instructed.

I'm a frequent shopper in the advance near me I used the TRT30 coupon code online a lot to pick things up for 30% for friends when doing work on their cars for them. I can just say they found it while I was on the way to the store and they will take it back. But I'm gonna re read your post and run the test then Ill post the results. If it is the ecu then advance has one and napa has one too.
