Even Bank Not Firing!!!

[7.3 Trever]

Hey guys i have a 97 f-250 7.3 and the even bank is not firing-the whole driver side of the engine. i scanned it and it through some codes but no major ones. Any ideas? im sure its something electrical considering its the whole even bank. Id appreciate some advice. i can list the codes if you want me too. Thanks alot

I assume you mean one side of the engine is not firing. There are plugs that plug into your valve cover gaskets that can go bad or even unplug.

yeah i have the valve cover off and made sure everything was good and tight. i wouldnt think it is the gasket harness because all of them are not firing. are there any relays or fuses i can check?

I have the same problem, except my odd bank is not firing. It's intermittent. It can be running fine at idle and I can race it up, then when the rpm's fall it starts missing badly and the CEL comes on. I can disconnect both left side valve cover harnesses while it's missing and there is no change, so I'm assuming the whole left (odd) bank is dead. I pulled the valve cover and everything looks good and tight. If you find a solution please post it.

If all the pigtails, valve cover gasket connector and Gp /Injector harness's are good....
IDM....................................B4 I'd replace it, I'd swap it out with a known good one from a friends truck, if possible.

I HAVE THE SAME PROBLEM ON THE PASSENGER SIDE. ALL I DID WAS CHANGE THE TENSION PULLY AND NEW BELT. WHEN I WENT TO START IT WAS MISSING BADLY AND THE CEL WAS ON. TRIED TO PULL CODE BUT CRAFTSMAN OB 2 DIDN'T WORK ON PSD. ANY HELP WOULD BE APPRECIATED

The valve cover harness' can get burnt or loose overtime. They do make little retainer clips to help keep them plugged in correctly. Check over basically everything chuck mentioned really well.

had this happen to me. drivers side went dead, check engine light, no codes, would randomly pic the side back up. the tech that i took the truck to while i was in school changed the IDM, thought he fixed it but then i did it again. turns out there was a burnt wire inside the valve cover gasket that was not visible. fixed it and been good ever since. valve cover gaskets are a lot cheaper than the IDM and it sure sounds like my issue, so i would start with the gasket.
