I got a 93 dodge dakota with the v6 3.9 swiched bodys on it and now fuel pump wont come on and engine wont even roll over any ideas to what is goin on

Did you keep the old BCM and ECM with the rolling chassis or did you use one or both computers from the new body?

Are you sure you have all of the grounds attached firmly and with good clean contact?

Used the old ecm and every thing and ground are good body to block block the frame rite?

Did you use the old BCM(body control module)? Not sure what you mean "ground are good body to block block the frame rite?" There are more than one ground points.

Yes used old bcm

I ran a ground wire to the body to the block and to the frame cause i took them off when i swiched the bodys

Ahh ok I understand now. There are more than one ground points though

Yup got all the grounds hooked up and made sure im just stuck with the fuel pump not coming on and the motor wont roll over when i rurn the key

Is the fuel pump any good? Can you hot wire it to hear it run to make sure its not bad? Does the starter have power to it when the key is turned to the run/start position?

Fuel pump is good and starter is good just checked it

Then its going to be in your wiring (broken/pinched/grounded/not hooked up) to them both, the ignition has a problem or the grounds. Are you using a volt meter?

Thank ya man And no volt meter

No problem. Get or borrow one or at least a test light.

Will do thank you again man
