    I just replaced the hall effect pick-up and at least the truck seems
to start and run. Because it was an intermittent problem I guess I'll
have to wait a few days and see. I only have about a 3 to 4 mile drive to work,
so I will test it out and see what happens. I will report back on my progress.

     Hopefully I can get it resolved before it goes in to get the body
fixed (new door, club cab panel and headlight bezel) and have the whole
truck re-painted. Damn deer or make that dead deer!
One way to help pay for a full paint job.

Thanks everyone for your help and suggestions!
