larry-56 No problem, Hopefully it might help somebody with the same problem figure it out.
Thanks klhanson for your post on just replacing the solenoid,never thought about doing that.

Thanks again Larry

klhansen Glad you got it figured out. And thanks for letting us know what the problem was.

larry-56 Well I finally got a chance to work on my truck again today. I ordered a solenoid from pensacola fuel injection. I replaced the solenoid on #7 injector cleared the codes and fired it up check engine light off finally. Thanks to everybody for all the help.

Thanks again Larry

Thanks again, Larry
Ford Motor Company Driving Cycle

Check the above link. It tells you how to complete the Ford Drive Cycle and clear the P1000.

Absolute Potential causes of a P1000 include:

The battery or PCM has been disconnected .
The diagnostic trouble codes have been cleared .
An OBD monitor concern occured before completion of the drive cycle

Possible Solutions Although this may be considered a common Ford DTC, it's very minor. You in fact can safely ignore this code and it should go away as part of normal driving, you do not need to clear this code (as it may not actually turn off the MIL). If you want to the code to clear itself, faster, run through the Ford Drive Cycle.

larry-56 Hi fellas,
So I finally got a chance to do some more troubleshooting and checked the circuits from idm to valve cover harness all show within specs checked 42 pin connector to valve cover harness looks lik itís good. So I cleared rather codes ran it for a little while and noticed like I said before Iím getting a little fluctuation in rpms at idle-not much that being said I checked the codes again and the p1316 and p0475 are gone but faulted another code p1000 Iíve been driving the truck for about a week hoping it would go away haha but check engine light is still on checked it again today and same code p1000 any ideas what to do next.
Thanks for any help. Larry

larry-56 Hey guys I havenít had a chance to do anymore troubleshooting on the wiring the weather has been really crappy and I have to work outside. So that being said I drove the truck today ran fine as usual but I did notice a little fluctuation in the rpms at idle looks like it was fluctuating about 50 rpms up and down just wondering if this has to do with idm code or something else.

Thanks again Larry

larry-56 klhanson thanks for all your help. I will check the wires at the 42 pin plug again,but not today Iím going to give it a break today cause itís driving me crazy haha also thanks to all replies.
02-14-2019 09:10 PM
klhansen The circuits all come together at the 42 pin connector over the driver's side valve cover. You said you had repaired some chafed wires over that valve cover, so that might be a place to start.

Good Luck.

larry-56 Yeah i know what you mean, not sure which way to go now the really weird thing is the engine is still running strong . thanks for your help if you can think of anything else let me know iím going to unplug the ebpv and go from there. Iím going to see if I can trace the ebpv wires and see if possibley they are in the same wire loom as the injector circuits wish me luck.

Thanks again Larry
02-14-2019 07:07 PM
klhansen That's strange. The EBPV circuits should have no affect on the injector circuits. You might have a short between circuits somewhere. Probably going to be real hard to find.

larry-56 Hey guys,
Iím still trying to figure out what is going on with this truck. So this morning I checked all the wires on the drivers side harness above and the valve cover no chafing that I could see.
So yesterday afternoon I checked the codes again and got new code p0475 and still had the p1316. Ive had the ebpv unplugged for years with no check engine light so i thought I would plug it back up and maybe the p0475 would go away but it did not but the p1316 did wit it unplugged I get both, plugged up i just get the p0475. Iím really confused now it doesnít make any sense to me.

Thanks Larry

larry-56 Thanks for the replyís. The truck ran about the same but I do have a little miss at cold start not plugged in but after it warms up it runs fine itís been doing that for a while with no check engine light. I checked the resistance and all were 3.3 ohms
I will check the wiring on the drivers side valve cover for chafing. I had an issue with chafing wires on the valve cover about 10 years ago and it affected all 4 cylinders on drivers side taped the wires and put some insulation around the wires and no issues since.
There is no corrosion on the plug or valve cover pins but I cleaned those with some electrical cleaner just to be safe side. I will also check the wiring from the IDM to the valve cover

Thanks Larry

You could also check resistance with a multimeter on the injector coil on the other injector coils and compare to 7 be for you swap them.
I agree completely. First check the resistance across each injector. Should be around 2-5 ohms, IIRC. You can do that from outside the VC. The pin to Injector 7 will be two pins back from the center pin on the connector. The center pin is common, and the location to each injector corresponds with it's position on the engine.

Solenoid coils don't go out that frequently, but it happens. If you find that #7 solenoid coil bad, you can just swap the solenoid with a core injector or order a coil from an injector rebuilder. No real need to pull the whole injector.

Also check where the harness runs across the driver's side valve cover for chafing. That's easily fixed with some electrical tape.

Another thing to do before condemning the IDM (assuming you find everything OK at the injectors and valve covers) is to run a continuity check between the valve cover connectors back to the IDM. The open circuit can be anywhere between the two. IDMs don't go bad that often.

The pins at the valve cover gasket where the wiring connects can also be corroded.
