97 Trans am...just replaced the waterpump and front seals,and removed air pump stuff, re-assembly seemed smooth but now it turns over but chugs then dies...would the air not tuned out do thid or do i have something out of whack??? Any help would be great.

 

Your waterpump is above your optispark. Make sure you didnt disturb any wires or if you dumped masive amounts of coolant onto it and it got inside it could mess with the ignition. Any codes popping up?

Wow got confused between the engines? well if you have stock lt1 then these suggestions may help.

Deleting the AIR system will not prevent it from starting. You did plug up the AIR connections on the manifold, correct?

In replacing the front seals, did you remove and reinstall the Otpispark distributor? If so, are you sure you indexed the Opti correctly to the cam dowel pin?

 

Yep the exhaust manifold got plugged, I thought I lined the Opti back up properly as it monted flush with the block(or timing cover).... can the Opti also be flush if the dowl was located into the other 2 holes in the back of the Opti??

 

Yes, although most people only manage to do that by pulling the Opti down flush with the bolts.

 

Seems like I will be tearing this back down to do some investigating....what kills me is that I thought I did it without issues as everything fell into place just fine....maybe have something loose or mis aligned....I will let you guys know later today as I tear it back down....Thanks in advance

 

Just one possibility. Are you sure all the wires to the ICM/coil are intact and in good condition? Have you scanned it for codes? Problems with the Opti (excluding indexing) and ICM will set codes during cranking, and not turn on the SES light.

 

Turns out the opti was NOT oriented right with the dowl....once that was right ...fired right up

Thanks for the help folks,,,,I am sure I will be on here again as I plan on doing multiple things to this TA
