Hi Digger,
Sorry, 92 Sunrunner. Would start on the propane and then continue running without additional propane.
I only got the call after one of them had pulled the disty out without marking anything and was assuming it was running before that. Now, that I know it was dead before the "tune-up," this is another whole kettle of fish and I am not getting signed on for any more.
After I couldn't get a response from the ECM, they called a guy in with a reader. He was really surprised that he couldn't get a response with his equipment and then proceeded to the jumper test.
This is the first time I have seen behaviour like this where it runs fine once started but otherwise dead. I agree it could be a short and am willing to pass it on but the only person I have to pass it on to is the one who pulled the distributor without any regard to timing. Frankly, I would say that they have bitten off more than I can chew again.
I will tell him to check the main harness connector and listen for the pump but I was hoping the reader being unable to raise the ECM was fairly smoking gun. I don't want to advise them to buy parts that may not fix the problem but they have been leading me on a bit (by not telling me the truth in the first place - I know that he is sheepish about having done the wrong thing) but I really don't have time for this and don't really want to extend my involvement by having them call me back for more directions.
This post is even turning into a book ...
Thanks,
Aaron
