A code would not come up unless check engine light is on is the truck getting fuel at the injecters check the shreader valve if it is than check spark.

    really? why would someone make a comment/solution, when they have no idea what they are talking about? stay out of it all, and let someone with experience and knowledge handle it.

The O/2 senser will not make it qit but the fuel pump and the ingition module will. does it start right back up? Fuel pumps heat up and quit sometimes opened the relay and it cools and or is cycled as you try to restart and it reclosesand you drive on. an amp test on the pump draw or even a scope test of the pump may isolate it as the bad boy. Pumps build up pressure and heat if the fuel filter is partly clogged. Change the filter as preventale maintanance and try to blow though the old one if it blows though hard it may be too late for the pump and you may have to change it too as the stuff that went thohg the pump that stopped up the filter. You only can heat the pump so much before its bad if you find it is change the relay also and check the ground wire where it connectes to the frame. The hanger unit that the pump is in fails too and it has to be changed on most models as you can't buy the pump any other way because it fails as often as the pump or is damaged as the pump fails. The ingtion ciol can fail, but not likly to start right back up you gota wait. The ECM cando it too but is not a common problem. Their may be engine control codes in the computer to help you determine the problem

2001 chevy silverado 2500 hd, 6.0, replaced fuel pump and it will not start. Put a light tester to the wire harness and it is not getting power. cheked the relay and it works. is there anything else that...


If you are sure the fuel pump relay is working, check continuity from the pump to the relay socket. These wires love to corrode. When you turn your ignition on, the fuel pump will only run for a couple seconds before it shuts off via the automatic shutdown relay. Make sure you are checking power within this window. The PCM (powertrain control module) is what completes the ground in order for the relay to send power to the pump. If the PCM does not recieve a signal from several sensors (mainly the Crank Sensor) it will not turn on the pump. You may want to check these sensors, is the check engine light on? You can scan it to see if any sensors have thrown a code. Be sure all applicable fuses are ok, the PCM may have its own fuse, check that even if the fuel pump fuse is ok. Your Truck may also have an inertia switch for the fuel pump which shuts it off during an accident. Check that as well.
