    As many of you may know my '72 had a slight wiring problem, and it acted as if possessed on the second day of the y2k run. In the course of being towed down from the top the mountain it decided to run without the ignition fuse. ?? After paying some of my dues with my wife, and waiting for a new fuel filter, I was able to finally perform a little diagnostics tonight.

    As for why it was able to run with the main fuse removed, I do not know, I can't duplicate it. I did however find that the wiring harness to the back of the blazer had been crushed by a rock. It also appears that the voltage to the fuel pump was dropped dramatically because of this. At this point I have restored the voltage, and I have replaced the wiring. Everything seems to check okay. I will try to restart tomorrow. I'm still going to cut the hole to access the fuel pump without dropping the tank, as the it is mounted in the tank. I'd like to thank everyone for thier help Sunday evening. Special thanks to Steve Fox, Steve and James Watson, Steve Frisbee, Lane Oberto and to those others who I regretibly do not remember the names.

    Glad to hear she's almost ready for the trail again, hey if you get a chance, take a few pics when you cut your access hole, I am thinking about doing the same thing and would like to know how it turns out.

    Well I did not get the hole cut but it is marked out! And the wiring is repaired very nicely now. If only I could find the way to remove Chistine!!!

    What kind of problem did you have with the computer? Do you have a TPI or TBI unit grafted into your rig? I kinda want to know cause I have a TPI on my 79 and always want to hear about any computer issues. THanks.

    The problem was out side of the ECM it worked fine, once I truned on the autocomp for alt. No the problem stems from the shorting of the fuel pump lead and the rear brake lock along with the brake lites!!! I replaced the wires from the bulkhead fitting (backside of the fuse block) back and ever thing seems fine. I would like to trade thought on fuel injection with anyone, and yes it TPI after market unit.
