Hey guys- I've been trying to get the Pseudo-Coupe started since the weekend after the motor swap, but still no luck. here's what I got:
-83 Tbird (ex 5.0l/AOD car)
-85 TC harness
-LA3
-255 hp pump
-all the appropriate other bits
I've got spark and the ECM is getting power (VREF is 5V and it spits out codes...all codes were for "cold" sensors and lack of BCS..so it's working). Timing is right (checked it 4 times...). After fixing a couple power wiring issues I could get the car to start by priming it with some starting fluid and it would run..just not very well and very rich. It would not however start w/out the initial priming. Now it won't start w/ the starting fluid. The plugs are REALLY fouled, but how fouled do they have to be before they will cause a no-start? Am I dealing with a case of fouled plugs and a "green" ECM that hasn't learned to play with the "big" fuel pump yet?
This is the motor out of the XR7 and aside from the LA3 swap, the only big change was to swap on a fresh head. I've got fuel pressure and what seems to be power in the appropriate places. I'm running out of ideas..
Anyone?
