Have you checked the fuse to your PCM to see if it's getting power?

You should always post the year of your truck (some will show cranking on the tach, some won't...)


WTS Light? - do you get it when you first roll-on the key?

Fuel - pump runs? Fuel refilling filter housing? Tank below 1/4?

Is your truck "chipped"? If so, remove it as a Test.

Under the "kick panel" of the passenger side there is what's called an "Inertia Sw", it kills power to the pump in the even of an accident. I would check that first (the plug sometimes falls off)

Next, you might need a pump if it's really not running (it only runs for like 15seconds after you roll-on the key so, check quickly by putting your hand on it). If you have one, try pulling the rubber off the power lead and connecting it to a Jumper Pak to supply 12v directly to it. If it doesn't run then you probably need one. If it does, go over the fuses again, in an '02 the relay that controls that is in the fusebox itself and considered Non-Serviceable Otherwise it's controlled by the PCM, via that Inertia Sw.

Well, then, "glow plug light comes on and stays on for about 8 seconds" doesn't happen with that fuse blown though....
