Rear subframe grounds??
 

I just swapped my rear subframe and now the car won't start. It cranks but won't idle.

I left the PPF attached and already check the one grounded right at the rear of the PPF.

Is there any other grounds that I may have missed??

Thanks

Fuel related?

Has spark?
Has fuel?
Has time?
Has compression?

I'll double check everything. I started and idled the car on thursday. I haven't touched anything on the car other then what was need to swap the rear frame. So logic would say it has to do with the swap.

Fuel and spark.

The motor starts to start. I can hear it fire but it feels as if the ecu isn't taken over and contolling the motor. Everything turns on fine and no new check engine lights. Same unhooked O2 and evop codes.

While it could be true your logic is off.

Correlation != causation
