Truck ran great with no problems until the other day. Got an oil change (I did go from 15w oil to 5w) and drove home between 5 and 10 miles now it won't start. Glow plug lights comes on batteries have been charged and the fuel pump sounds like its working. Did a little research and it sounded like I had a bad cps well 27 dollars later truck still won't start. Also all the fuses look good.
Any ideas I'm stumped???
I've heard of people in really cold climates using 5W. Try unplugging your ICP then starting. Also drain the fuel bowl and see if it fills back up. Are you getting white smoke while cranking? You may need to get a hold of a scanner to see what's going on.

I live in Michigan been a pretty cold winter and hasn't been a really easy start so I tried thinner oil in my quest for easy starts, it is rotella synthetic 5w 40. No smoke when cranking I will drain the fuel today and see if it fills back up. I'm also running up to the store for a scanner hopefully there will be some codes. Will let you know
Not only should the fuel bowl fill up, but with the drain valve open and the key turned on you should have a 40-50+ psi stream of fuel out the bottom of the engine(where the fuel drain line goes) every time you turn the key on for 20 seconds or so. The fuel pump will turn off after that if the engine doesn't start.
Also make sure the battery voltage doesn't drop below 10.5vdc while cranking.

Well here's some codes:
Let me know what you guys think I killed the batteries cranking it (they weren't great to start) so I'm thinking some of these codes might relate to that. Anyway trucks getting a charge any ideas on where to go from here?
P198-EOT sensor circuit high input
P1280- ICP circuit out of range low
P1670- EF signal feedback
Normally, the 1280 code would be the issue, but you unplugged the ICP. The EF malfunction could be an issue, but is normally just a ghost issue. EBPV, no problem, as well as the KAM error. The 0605 code could be your killer. Try unhooking your batteries for a few minutes (or clear codes if your scanner will do it) and crank again. If the 0605 code comes back, it means an internal failure of the pcm. Are you running a chip? If yes, remove it first.

Well I took the truck into the dealer looks like they are trying to tell me all 8 injectors have failed possibliy because of the oil is this possible? What the cost I'm looking at this this from a ford dealer I'm a little nervous here.
Well dealer wants $3900 for 8 new injectors. Having said that I'm getting a second opinion from a small shop. Owners son is a powerstroke guy and seems to think the IPR might be the cause but hasn't seen it yet. Anyway he's going to diagnose it tomorrow hopefully ill keep everyone posted.
