Yes, truck ran perfectly all day. Drove @250 miles, loaded the wagon, drove @100 miles and that was it.

Unknown brand, could have been the stock ones. Truck has 300k+ miles. The only sign was blowing lots of gray smoke and a miss and a slight knock at idle. I didn't pick up on the smoke right away as it was dark and foggy weather. Babied it to a truck stop and elected to tow to a nearby shop, but the damage was done.

#5 injector cracked and was dumping fuel. Hashed up the #5 hole and beat up the head. The cylinder is just past the limit for boring. Messaged you....

Looks like I hashed my engine. I'm not finding many good used ones, so considering a reman unit. Are there any decent reman companies out there? Checked Jasper and their prices are pretty high. I really can't justify $10k to put an engine in a 20 year old truck that's only worth about $10k......

Thanks guys. I ended up ordering from High Impact. Their remans have all the updates, price was about the same as everyone else, with a 2yr warranty. Seemed the best value for the money.

Looks like my NV4500 trans hashed itself. Looked online, saw Midwestern and SP Precision. SPP has them on sale + a lower core charge. Anyone use either of these places?Any other rebuilder recommendations?

Updating the thread....... Looks like I need an alternator AND an ECM. Sometimes I wonder why we keep these old trucks. Fix one problem and find two more............ Thanks for all the input guys!

AC noise test is on the agenda for tomorrow, I'll update the post after. Thanks for the info guys!

No, left it unplugged to be sure.........no WTS light. Okay, in the event I need a new ECM, where is a good source for one?

No WTS light. Waited @2 minutes, no light, and no grid heaters. Possible solutions short of replacing the ECM? I'll replace it if needed, but I'd rather cover all the bases before doing that........ I've seen a lot of posts ( here and other sites ) where folks with this issue are not able to start the engine at all, and mine starts and runs normally. Any idea why? Also saw some posts that say that 1693 code cannot be seen by itself.......but it's the only code showing on my truck.

I really can't say, didn't see it, but the truck had been plugged in and it was actually very warm outside. I left it unplugged for tonight, and will check in the morning when I know it'll be cold enough to run the grids........

Truck in my sig...... This truck has had a FASS 150 on it for @10 years, has and still does work correctly. Up until yesterday, key "on", pump ran a couple of seconds, or bump the starter and pump ran for @20 seconds. Yesterday, key "on", no pump, bump the starter, pump runs a few seconds and shuts off. The FASS is run with a relay plugged into the factory lift pump harness. The truck starts and runs, and maintains @14 psi constant after being started. I unplugged the FASS harness, tested the relay and the harness, checked out ok, and the pump runs with 12v direct to it. Key "on", the factory lift pump harness shows 7v, bump the starter it goes to 9v-10v for a few seconds, then back to 7v ( I neglected to check voltage there with the engine running). The factory pump harness appears to be intact. The CEL is not on, though my scanner picked up a companion code P1693, but it didn't specify what the problem is. Also, I cannot clear this code. Any ideas on what has failed?

Might work. Dynamat and Boom Mat are two products made for this purpose. I haven't checked prices. If you don't want to piecemeal your own setup, Quietride Solutions makes various kits for our trucks. More expensive, for sure, but everything comes in one box and away you go. www.quietridesolutions.com

Bringing this back up...... Did the diagnostic, everything checked out okay. Still getting the intermittent P0222. The code only seems to come up when I have the truck under load (4th gear, heavy throttle, pulling maybe 10k load). Could the Timbo APPS be causing this? It is an older unit, installed 8 or possibly 10 years ago.......

Hello all, My '99 is throwing the P0222 code. It can be cleared, but recurs intermittently. The engine does not derate, seems to run normally. Possible causes? Solutions? Truck is mostly stock, but does have a Van Aaken timing box, and a Timbo APPS.

Took me a while, but I got it. The o-ring wasn't the problem, there was a ring of corrosion at the edge of the hole that was preventing removal of the sensor. Ended up drilling it into pieces and removing it that way. Thanks for all the advice!

I attempted to change out the crank sensor today. And of course, it broke off. I screwed in a long screw and pried with a pry bar, it moved a short distance, but is wedged in there pretty tight and won't move any further. I'm considering drilling it and removing it in pieces. Input? Any other ideas?

Kind of an odd issue........ Went to start the truck, was kind of cold, ran the grids and truck started no problem. Drove a short distance (@1 mile), the engine stumbled just a bit (maybe 1/2 second), and check engine light lit, then it ran normally. Ran a couple miles, stopped and scanned it, threw a code for the crank sensor (I think it was 0336). Erased it and restarted the truck, drove @6 hours with no issues. Couple days later, another cold start, moved the truck maybe 150 feet and shut it off to load up. Restarted it (no grids this time), a short stumble and got a check engine light. Moved it maybe 200 feet, shut it off, fueled up. Scanned it, same code, cleared, then tried to start, no start condition. No check engine light, just no start. Waited a minute or two, restarted, and got a check engine light. Ran it for @2 or so hours, stopped, scanned, same code, cleared, restarted, and ran for 2-3 hours with no issues. Stopped for fuel, restarted, ran 2 hours, no problems. I did order a new crank sensor, but I've never had one act up like that. Any ideas on this?

Okay, I did the diagnostics, everything checked good. Reconnected everything and scanned and erased the codes......and they stayed erased this time. I don't know why they appeared at all, but I'll take it as a win. I'll drive it to work tonight and see if everything remains okay.......

I'll check it and update the post......

I did the checks in the article.......got 4.6 volts at both IVS#1 and #2, which would be correct according to that info. Still have the recurring code though. Any ideas?

Thanks guys. I'll update the post when I resolve it.

I just replaced my intake manifold gasket, checked/adjusted the valves, and swapped in some injectors (on the truck in my sig....). The truck starts, runs, and drives, but I have a check engine light with the P0222 code (APPS low input voltage). When scanned, it actually shows two P0222 codes. I erase the codes, but they immediately come back. Any ideas on where to start looking?
