truck runs for 30 sec then dies help!!!!!!

yes the green wire goes out before the it dies

If you hook 12 volt power up to the test/prime terminal and it runs? Then it would have to be the ECM? If wiring is correct. Is it consistent 30 seconds each time? Will it start after the stall?

Here's a link to diagram.

Do you have one of these on your harness?

[lilhupper]

yes its a consistant 30 sec and will fire after stall. no i dont have that.

[lilhupper]

puting a constant power to the test wire doesnt help motor still runs for 30 sec then dies. does anyone know what the fuel mod does. im going to go over the wire harness to night and make sure all wires and hooked up correctly and none of them are pinched.

What fuel mod? The Fuel module that came on some HD trucks? It runs the fuel pump for 20 seconds after key off.

I think you have some wires wrong and it's tripping the relay? Or wrong relay? You said it was from a 2.5L?

[lilhupper]

yes fuel pump relay are off the 2.5 tbi the wiring diagram has a hot fuel mod that i dont have. the fuel pump is tripping ill try puting the 350 relay on too

Might have lost the B2 signal when removing the Fuel module? Something is wrong with wiring?
