Early 944 Starts then dies
Just replaced the engine in my 944, starts, runs at idle briefly and then cuts out.
Things ive checked-
-Grounds all look good
-No vacuum leaks
-Fuel pressure good
-ref/speed sensors are okay I think
-All fuses okay
I am running out of ideas to try... I think the DME is cutting the engine when it does its self check after startup. Does anyone know what sensors it goes through?? If i unplug the DME Coolant temperature sensor the engine will run roughly, but as soon as i plug that back in the engine dies. I tried replacing that sensor with 2 different used ones that i believe are good with no success.
My AFM and TPS should be good because they worked with my last motor, but since a have all kinds of spare used parts laying around, I am going to try swapping those out individually tomorrow.
Let me know any ideas you have, I am running out of even wild guesses lol
