Truck just stopped and won't start. it turns over but won't start. is this afuel pump problem?
You'll have to figure out if it is a fuel or ignition problem to proceed.
Check for spark at the plugs, and fuel pressure at the injectors.
You might want to check the computer for trouble codes too.

ok... there are a couple of things you can do. i must have miss typed on the cap,rotor . in the back of the motor where the plug wires conect that is the cap that is bolted to the distributor with two torques bits that i believe are t15 in size. there may lie your problem. the posts inside are made of aluminum and they get coroded and dont alow the proper spark. the other commen problem is the exhaust the catalitic converter becomes pluged up. something you can try is remove one of the oxigen sensors and try to start it up if it runs the cat needs replaced. the o2 sensor is a 7/8 nut to remove it. give it a try

Check the Ground wire which runs from the fuel pump to the back of the truck. Had this very prob myself.

Does it have a trailer hitch and wiring? If so, check to make sure connector is not shorted out and double check your fuses and/or replace fuse. It may look good but I've seen some that were burned out of inspection view. You might also want to trace wiring back to brake lights, just in case snow or build up pull connectors apart.
