Need help with Diagnosing Hard Cold Start
I have a 2001 F250 w/ 7.3 Powerstroke. It's also a California truck, although I live in Colorado now. About 3 months ago, I had a new cam sensor installed by the dealer. About 2 months ago I installed a Quadzilla 4 bank chip (plugs into the computer) with the Commander and a 4 inch exhaust. About 1 month ago, I experienced the 1st cold start problem I've ever had.
When the water temp is below about 45 degrees, it won't fire. We've installed new batteries and a new glow plug module to no avail. Mechanic has checked the glow plug relay and the glow plugs and he says all are fine. If I plug it in, it starts right up. Problem is, I cannot plug it in at work, or when I'm on the road.
I removed the chip, but that did not help either.
All roads lead to the glow plug system, but cannot find anything wrong with it. Ideas? I'm about $550 into this so far with no answers.
