Fuel issues

[swettysblazer]

So my brother drove to school on Friday, parked his truck for like five minutes to pick up his g/f and went out to start it and it wouldn't fire up. Kept trying for about 20 minutes, nothing so he got a ride to school. Came back to the place it was parked, and it fired right up. Jumped in drove it home fine. Parked it in the driveway and tried to start it up again. Nothing. Didn't drive it over the weekend, and it pulled the same thing today, except he got to school and went to start it after school and it wouldn't start. Me and my dad thought it might be the fuel pump was too hot or something, but now that doesnt seem to be the case because it sat all day and wouldn't start. Any ideaas??

Ignition module, VERY COMMON failure point of all GM vehicles with electronic ignition.

If it's fuel injected the module sends a signal to the ECM so that can affect the fuel delivery.

We put in a new ignition module this morning, still nothing. All the wiring is correct, everything went back the way it was supposed to. Any more ideas?

What kind of truck/year/ are we talking about? Is it the one in your sig or something else? A little info would really help.

The next common failure point is the pick-up coil. Don't confuse this with the ignition coil. The pick-up coil is located within the distributor and the distributor has to come out and all the way apart to change this piece. At this point I would do a little testing before replacing anymore parts. On a side note, throw the old ignition module into the glovebox as a back-up.
