96 7.3 powerstroke won't start

This truck has ALWAYS struggled to start in cooler weather. Even at 50 degrees it needs the block heater plugged in. The other day it was borderline and I tried to start it without the block heater. To me it sounded like one side of the motor was firing but the other wasn't. The whole truck sort of rocked side to side. Lots of white smoke. Now it won't start at all (neither side firing). Any ideas? I am in the boonies and do not want to tow this to a dealership.

Check the relay for the GPs...causes alot of the hard starting issues. But @ 50*, she should start with no issues.

As far as 1 side not firing, check your UVCH. I had to replace an IDM a cple months back on a 96 f350...only 1 bank was firing. This was after replacing the UVCH onthe right bank.

you getting any smoke from the exhaust? neither side....check the UVCH. I'd say the IDM is shot. You got anyone you can swap one out with, for testing purposes? The IDm is costly, and I'd hate to see anyone buyone without knowing for sure it's the problem....

no warning lights of any kind...

UVCH is the wiring harness under the valve cover, right?

Thanks chuck.

no luck

Okay, in response to user's advice, I tried a different IDM in the truck and it made no difference. Still not firing at all. Where should I go next? I am lost here...

i have a 96er myself, the only 2 suggestion that i can offer are the ones that have been suggested: Under valve cover harness & the IDM. i've had problems with problems w/ both.

wait.............as i was typing, i thought of something. high pressure oil pump could be going out or the HPOP reservoir is getting low.

if you see a light at the end of the tunnel, it's probably just a photon torpedo

okay, Here is a newbie question. I have no problem removing the valve covers to check the UVCH and plugs, but if that doesn't work, I am at a loss and will need to take this in to get a professional opinion. Can the valve cover gaskets be re-used if they take them off again in the shop? I would hate to pay for them twice. They aren't cheap.
