I have a 2000 chevy 2500 van 4.3 liter, it dies then it wont start agian, will be ok for one week then it does it again. Dealer said ecm was ok that it was the fuel pump, I replaced it but it didnt solve the problem, it has no codes, fuses ecm1 and engine 1 seemed to be shorted together. You can pull either one out leaving other and it will still run. When its running cigarette lighter works. When it doesnt cigarette lighter doesnt either, all other acesories work.I am lost now can anyone help?
