I just dropped a used 302 from a ltd in the f150 and it won't start! i narrowed it down to a prior command start in the ltd, is there anything from the ecu or any other electricals i need to remove? or if anyone has a installation manual? also they are both efi.

 

sorry the command start is a cs3000

 

Are you using the LTD's ECU?

 

no i'm using the f150s. phoning a command start installer today cause i'm sure they will have a manual or something

 

Run the LTD's! The harnesses & ECU should go w/ the engine.

 

Can someone tell me quick where the ecu is located on this truck!!

 

Usually behind the left or right side kick panels. Start w/ drivers side next to the E-brake.

 

Okay replaced the Ecu, still no luck, truck will turn over all day, it seems there is no power getting to the fuel pump? could it have something to do with the command start? I'm not getting any power to the inertia switch anyone have any other solutions?

 

Run a KOEO (key on engine off) Error Code scan. The PCM relay actuates the F/P relay. And you know what the F/P relay does!
