1999 Yukon Start Issue - I have replaced the octopuse, battery, fuel filter, fuel pump, still having problems starting in cold weather, sometimes after a heavy rain.
Any suggestions?
Thanks
Check the condition of the wiring coming off of the ECM. at the fender. I've seen the wiring insulation rub off causing no starts.

Sounds like same problem I'm going thru right now. After setting for hours, starts hard. Eventually just stopped starting altogether. At shop now.
Had replaced fuel filter, checked fuel pressure (58lbs) held steady after shut down for over 5 minutes with little decrease in pressure.
I have the same issue. Over the past few months I have replaced the Fuel Pump, fuel filer, EGR valave, PCV Valve, and just recently the ignition coil. It ran fine for a day and then back to having hard starting problems and misfiring at speed. I'm heading to the store right right to pick up and change the crankshaft position sensor. It the only thing I can think of that it might be. If this doesn't work, I may change the camshaft position sensor.
More to follow....
Good luck
i just change my fuel pressure regulator and now the truck wont start did i do anything wrong is there a restart bottom.
1989 Toyota with 3.0 it starts an runs for 3 to 4 seconds then dies I put in new fuel pump an fuel pressure regulator an new plugs an wires an cap it loses spark when I try to start it again I also had a different coil an a different computer an tried that still nothing
