I replaced the rear bumper and pass. tail light assy. After that the truck would turn over but not start. I
removed a pigtail assy. that was welded to the old bumper. I thought perhaps a ground wire may be the
problem and reconnected the pigtail ground wire to the frame but this did not solve the problem. I put 2
more gallons of gas in the tank, I swapped the Auto Shutdown Relay with one of the other ones in the
Power Distribution Box (those relays are all the same), I checked the notorious "splice" 3 into 1 wire
potential. I have spark at No. 1 plug wire, put gas in the throttle body and the truck fired up and ran and
then died again,
Is this just a coincidental fuel pump going bad at the same time I replaced the bumper. Is there an
automatic fuel shutoff switch that engages when the bumper gets moved in case of collision?
Any ideas????????????????????????????/
