Swapped in a new DE. I tried starting it and it cranks over but does not start. checked spark and there is none. Checked the crank and cam sensors and they are plugged in. any suggestions?

A little back ground: The car is an 03 and the motor came off an 04.5. Im still using my 03 wiring harness since the one the motor came with was cut up. Is my ecu maybe not compatible with the new motor?

ran engine codes and got P1031 and P1065. P1031 is for the 02 sensors and P1065 is the ECM Power Supply Heater

 

oh btw think its odd but not sure if its related but i don't have to press in the clutch pedal to try to start it.

 

That's what happened to me when I swapped wives at the party....oh wait. You meant swapping engines!

IIRC, your issue may have something to do with the harness. I'm not sure, though. My memory sucks sometimes.

 

the coil plug grounds are just a looped metal connector that is just mid harness. It used to be terminated on the front timing cover.

See the black wires on the top right of this pic, check for them

 

I would fix the clutch pedal thing too...thats not a good sign.

 

Mine has something like that but not completely the same looking as that one. Heres a pic of mine

 

any suggestions?? i think this weekend i may just fix whats chopped on the new harness and put in the new one
