OK, wrote down some actual values versus going off my Pendleton compromised mind (last nights New Years Eve party was good! :) )
Staring into the PMD connector, tab up, left to right. Left two pins being the Fuel Solenoid wires.
95 K2500, runs great, using it as the "control" 95 K3500 is the...
OK, tested some more, probably going to pull the intake to inspect wiring, putting the multimeter across the two pins I get a relatively low reading (0.9 on the 200K scale) but going from battery ground to pin i get like 30 on the 200K scale. would this be more likely a wiring issue?
I am...
OK, pinout helps immensely, thanks guys!
I checked with the multi-meter set on the 200K Ohm scale, and got a reading of 30 or 300 on the main fuel solenoid (left two pins on end, red and black), and zero on a known running pickup
Pretty safe to say main fuel solenoid is shot and IP needs...
OK, cleaned most of the grounds today, got the one unhooked from the bellhousing bolt and back up on the intake where it belongs. Got the frame grounds. need to clean the firewall ground.
Changed fuel filter, looked OK. last ditch screen gone, put a good used one in. Possible the IP inlet...
Nice find! On your tach not matching the supposed ratio, double check the glovebox codes to see if axle tag and original build match, and if so, check alternator pulley. if it has gasser pulley, that could be why its off.
On the diff oil, 80w90 is supposedly 3,000 mile change intervals, 75w140...
OK, back at it since farming is about done for the year.
I put a new positive cable (pass batt to starter) in, that helped a bunch. along with better batteries.
Now I am getting fuel to the injectors, seems to go in cycles, some times it smokes good, other times not so much.
Spraying a little...
sorry, yes, the metering solenoid. Not shutoff.
The burning up due to incorrect depth might explain his current situation, lol.
I assume anyone that is eating PMDs could be caused by a improper depth FSO?
Nothing yet. :) back burner project ever since wheat harvest hit, I did get the 95 GMC K2500 back on the road (Genuine Bosch new injectors and AC Delco 60G glow plugs, new valley hoses, FTB, low mile GM8, and new batteries and ALL battery cables with the bolt mod, cranks sooo much better.
Then...
I picked up a GM set for 80 bucks off Amazon, I threw my back out earlier and am still recovering, so no door man-handling for now, hopefully can get them installed before too long.
I would definitely send them back if you have the option to.
Normally I am a big GM/ Delco OE parts fan, but it seems they take the cheap route on suppliers for alot of the 6.5L fuel system. Much better off to get a set of new Bosch from Leroy.
Is the EGR system still intact, even though the vac pump is gone? If so, need to delete that crap, I "think" but dont know, that the EGR valve needs vac to hold shut, so if there is no vac its always sucking exhaust.
Advice: Stay calm, dont get stressed, sounds like the previous owner did some...
Any more input on this? Looking at a 5521S and its was a no-go from the start for the owner. He paid 1200 and is accepting offers. I am debating about offering 200 bucks. I think he will take it if I do...
I dont always use 4wd, but when I do, Its once a year or so, and it usually ends up in me being frame deep with false trust in the abilities of a transfer case equipped vehicle... :)
the (2) 3/4 tons (93 and 95) are open diff, and are a huge disappointment in 4wd. my 06 Duramax with highway...
