99 PSD Starting Problems

I am still having problems getting my 99 F350 4x4 to start; it has new glowplugs, relays, fuel filter, K&N FIPK, valve cover gaskets, oil, and oil filter. It has been to two mechanics; a performance shop and a certified Ford diesel mechanic; both of them said the same thing; they plugged in their computers and all the levels were where they needed to be and all the sensors, voltage, and everything else checked out fine; it just won't start unless you have the heater plugged in, and this has been at 64 degrees outside! The one explanation (from the Ford mechanic) is that the powertrain computer may have developed a habit because the company that owned it previously had a policy that all their trucks had to have their heaters plugged in if it was going to be 60 or below outside. Anyone ever hear of this? Also, they don't have an explanation as to why the "Service Engine Soon" light comes on when the turbo starts to spool up. Any ideas? Would having the Ford Dealership flash the computer help fix these two problems?

Sheesh! If that SES light is coming on then something is going on. Ford, and many other places, have scanners that can connect to the data port and capture live data while the truck is being driven. Nobody is digging deep enough to solve the problem.

I agree, if the SES light is coming on when the turbo spools up then they should take a ride with you. A month or so ago mine acted up(not exactly, but similar to yours) and I found that the ICP plug had backed off just a little bit. I had the wires going to the 10k mod under there which was forcing the plug off. This may not have anything at all to do with what yours is doing. I hope it turns out to be something simple. Good luck.
