Back to your question about the 5068 pump: it was a 1 year special breed. It was a higher output pump than the 5521 pumps. It had a special EPROM to run it. If you mixed up the EPROM or the pump that was not compatable with the other, all sorts of fun would erupt with funky idle, and...
High ambient temp... with a/c running? How's the condition of between the radiator and the a/c condenser? Bug cemetary?
If that proves out ok... an HO pump would be nice.... but you didn't seem to be pushing it to get those kind of results.
I did see a guy once who had issues... and he...
Generating or consuming 38A? Generating read off of the alt lead itself. 38A steady from start up for a straight 22 minutes?
Anything blowing a lot of heat toward that alternator like some sort of exhaust leak like a blow torch on the alternator? Just grasping at wild crazy ideas....
This is an old one where the dealer sells you a tank cleaning with IP install. The old original design of the DS pump had steel rollers. They changed to low sulfur (the prelude to the ULTRA-low sulfur of today). The steel rollers would fail and contaminate the tank via the return line. Since...
Man, EGR was something I never had to contend with. OBD-II systems are a bit more fickle that the OBD-I systems.
Vacuum system ok? Seems to me there is three solenoids on an "S" engine. Solenoids very similar to the wastegate solenoid setup. Could it be the solenoid is stuck at max vacuum...
I think you're gonna need a DC amp clamp to check to see if you have a load, or a generation issue.
Too many things checkout... unless did I see that you said "Autozone Gold" like their in house reman brand? Maybe a bad run of those alternators... but that many in a row is toooooo odd...
Once it codes, it goes into backup timing. You'll notice your cruise will not work. The service engine won't light until next key cycle sometimes.
My first IP would sputter and do all sorts of stupid stuff at higher RPM's. If the computer is guessing at timing because it thinks it's inputs...
If during that engine running cycle, the computer pops another code, cruise will be disabled. Next key start, cruise will return until next code event.
Improper fuel flow, bubbles in fuel etc will throw the IP in fits and give you codes. Unless everything is running properly, I would not...
Drive with fuel cap loose. May have a problem with leaks in fuel lines too (rusting and getting pin holes) It's probably a locking GAS cap, not a diesel cap... different animal.
Scanning for engine codes would help too. Just because you don't have a service on, doesn't mean that code...
Is it a slow drop in voltage, or just drops off suddenly?
The regulator is inside the alternator. As the alternator gets hotter, the voltage tends to go lower in mine. Cold winter morning 15+ volts/Hot summer day 14 or just under if you are lucky on the dash.
Got an DC amprobe/amp...
I just got the email in my box that this thread has come back to life.... howdy folks! Thought of you all often.... I just don't get a whole lot of time in front of the computer except for research, work, and a quick check of facebook... Hope to come back around...
I think of you everytime...
I think the OPS is just an "in the ballpark" reading. Several have posted over the years vast pressure readings on dash when OPS was changed. I guess to really be sure of what you have, use a mechanical oil pressure gauge....
How's your voltage drop on the dashboard during wait to start? Both Turbine Doc and I had glow plug relay meltdowns. This is where the plastic would melt on either side of the posts, and not allow contact internally (thus no power during the wait to start). Mine was an OBD-II system, so it...
Well, I haven't defected to Ford sites... I just haven't been on any sites at all... demands of life have just taken over. I still want to stop by here every so often and chip in where I can.
Doing well... took trip to NC (about 7 hrs away in January) ran great.... Now that my teaching job is winding down, I hope to pop in every now and again.
Very interesting thing... I would lean toward ignition switch issue... but the WTS should still come up. WTS fails to come up on ECM inital power up from battery. Ignition switch failure only cuts ignition signal to ECM, not all power to it (like cutting battery power)....
Very very...
