Well the car wont' stay running after I changed the Radiator (to F-body Rad) and to a 160* T-stat. The funny thing is that I had it running right after I did the swap for about 15 mins and the temps never got about 175* when it was sitting idle. I checked the coolant, rad and overflow tank is filled properly. No Air is in the lines that I can see or feel. I squeezed the lines to try and push the air to the Rad. Now after a couple days later the car wont even stay running. I thought it was getting hot or something. I get no symptoms that it starving for fuel. It just cuts off (no bucking or stuttering, nothing) after about 5 mins every time IF I get it running, then I can't get it started unless I wait for about 30 - 40 mins. These are the things that I checked:
Battery is good, constant 13.6v
Alt is good, Its charging good also.
Plugs are good, I'm getting spark (I can get it running, when its first started)
Wires are brand new stock version,
Coil pack is good,
Ignition Module is good, no grounding inside where the wires are at.
I check the ground and their right (near the battery) none are broken (both on the side of the vehicle and behind the engine)
No Vac leak as I replaced most of them.
Check Fuel pressure and the regulator (41 with line on. 38 line off) both good.
I thought it was fuel but the pump is still pushing good fuel.
Replace LT1 maf with stock maf and TT chip back to stock chip, then resetting the ecm. ECM was getting warm tho.
Checked wires ( starter, grounds...)
Fan comes on like it should.
I haven't changed the ECM to another one yet...still looking for one.
I doubt its the crank sensor (since I can get it running) but how do I tell its bad or not. Guess I'll keep looking.
Could I have knocked or moved (cam sensor) something, just wanted to get some info on where to look or if someone has similar problems where I could look to get more info at before I send it to a shop to have it checked out. I know I'm missing something to check but I can't think of it for the past 2 days.
