97 3500 DUALLY MOSTLY STOCK
 

I have put a new lift pump in, replaced the shutdown solinoid and made shore the fuel was primed, but the truck starts up runs for awhile then starts dieing. Can someone help?

Pinch off the return line from the injection pump and that will test the overflow valve. Check the lines and fittings to see if it sucking air. Will it run with throttle or dies no matter what?

HELP
 

I WILL TRY THAT PINCHING THE RETURN LINE WHEN I GET HOME, THANKS TO ANYONE WHO CAN HELP
