OOPS! Sorry, wrong forum. <BLUSH> Moderators, please delete.
Hi folks,
I would like to toss this out, because I'm new to owning a PSD. But I do have a long and experienced background as an ASE Master working in large multi-line GM dealerships.
I just purchased a 2007 F350 XLT SC 4x4 DRW Auto. The truck has 148,500 miles, is completely stock except for a B&W gooseneck hitch, headache rack and toolbox. It seems to be in excellent "mechanical" condition. No leaks (other than some minor seepage from the back of the engine pan and both rear axle seals), fluids look and smell good, belt and hoses look good, starts perfect, runs smooth, has good power (boost seems normal), no smoke, shifts normal, drives like new. Hour meter says 3128 hours. No evidence of any (shoddy) work being done anywhere, especially under the hood (no obviously misrouted wires, lines or broken connectors etc).
So, I test drove it about 10 miles and it was perfect. Close visual inspection was good. Price was $14,999, so I bought it (traded in a 2001 Jeep WJ for $4,500) and left $11,335 lighter in the wallet.
Drove about 50 miles the first day/night. Next morning drove to work (25 miles) and everything was perfect. Left work and about 1 mile from work the CEL lit up (steady on). I didn't notice *any* driveability related symptoms. Still running smooth, shifting normal, good power, no smoke etc. Got home and swung by AutoZone and pulled 12 codes (4 were duplicates). The codes were:
P0261 - injector 1 circuit low
P0264 - injector 2 circuit low
P0267 - injector 3 circuit low
P0270 - injector 4 circuit low
P0273 - injector 5 circuit low
P0276 - injector 6 circuit low
P0279 - injector 7 circuit low
P0282 - injector 8 circuit low
Hmmm.... OK... I go home, do a close visual inspection under the hood again and find nothing. So I disconnect both batteries for about a minute, reconnect them and fire the truck up. Same as before, all systems go and no CEL.
Wife I and go out and drive around for about 20 miles and everything is perfect.
I drive to work this morning and about 11 miles in, the CEL lights up (steady on) again. A co-worker just happened to have a Actron code reader (same one the AutoZone guy used), so I go out and plug it in and low and behold, it says 12 codes (again 4 duplicates) and lists the same thing.
Right now my thoughts are:
1 - No way all 8 injectors are having the same issue
2 - Some of the codes are "history" and I did not really "clear" them when I disconnected the battery, even though it did reset (turn off) the CEL.
3 - The CEL lighting up is probably one (or possibly more) of the "injector circuit low" codes.
4 - This is, likely and electrical problem in which all 8 injectors share a common relationship such as a loose or poor ground connection, loose or poor harness connection etc.
Now, I am pretty good at diagnosing electrical issues, but at this time, I do not yet have a FSM (I was surprised how EXPENSIVE they are for this truck!!!), so no wiring diagram or idea of specs to check (resistance, voltage etc).
Ideas, suggestions? Smart remarks? Funny one are appreciated too.
Thanks!
