cold starting help
i have a 2001 f350 7.3, had problems last fall with cold starting wouldn't start with temp. aroud 40, found out that the glow plug solenoid was bad, replaced it and day or two later the new one stuck on and drained batteries, got new solenoid from ford and two new batteries it was better but didn't want to start now around 32-34 degrees so i figured a couple glow plugs were bad cause with it plugged in it fires no matter what. So i just finally got around to changing glow plugs, solenoid (again just to be safe), valve cover gaskets and harness under the cover and still same problem. Now if i go out in the morning when its cold i crank it for 3 or 4 seconds then turn key off and do the routine a second time (key on, wait for light, crank engine) it fires immediately. I checked all new glow plugs and they have readings of around .9 ohms. I also checked to make sure that the solenoid is staying on long enough for the glow plugs to get hot and it is. The only other thing i have to check tomorrow is to make sure there is voltage going to the glow plug harness and to make sure that when the solenoid stuck that time that it didn't burn up one of the fuseable wires going to it. Just want to make sure im going in the right direction. Any help would be greatly appreciated.
