Hello All,
I have posted this @ TDP forum and have not had too much success. One of the members had mentioned that I should try posting it here i might get better luck.
I have been racking my head on this one. The truck was running just fine and I got the normal symptoms that the PMD was going so I went to the dealer and bought a new one. Hooked it up and this time it did not run like it should. So I went back to the dealer and they exchanged it for another one. Again no improvement.
Here is what she does starts with all kids of white smoke “when cold” then after give it about ¼ throttle the smoke goes away and she runs real rough “all the time” and the rpm’s are all over the place. No SES Lamp.
Sometimes she will start and the SES light will come on and the idle is perfect a bit high though, drives fine! Then I turn it off and re-start right away and back to the rough stuff again. Unless I fuss with trying to rev her and then she’ll fish bite and the SES lamp will come on and bang runs smooth again. I read the and I get the following: in this order 18,35 and 54 but I don’t always get the 54 code I did get 19 a couple of times, however I think that that was due to low batteries. After I cleared the DTC's and charged the batts it has never came back.
I have replaced the batteries and the cables and the checked all the grounds.

1h] Does the Service Engine Light Glow during Start/bulb check? Yes unitl truck starts.
2] Fuel Issues (if not running):
2a] Can you hear your lift pump working? Yes
2b] Do you get a steady flow of fuel from the water drain (T-handle) ? yes about 4+ PSI when trying to keep it at an idle.
2c] Loosen the inlet line from the IP – is fuel coming out (Lift Pump on)? Yes
2d] Loosen an injector line and crank the engine - does fuel come out? Yes
2e] Do you hear a vacuum (hiss) when you remove the fuel cap? No
3] PMD / IP Issues
3a] Location of PMD (on pump, on intake, remote mounted) Remote mounted
3b] Condition of Extension harness (if used) Vendor or Homemade? Great, Homemade, retested 0 resistance and no cold solder joints.
3c] Condition of grounds / ground wires to IP / PMD. Check Harness. Re-cleaned and bonded.
3d] PMD Make: Stanadyne Part #35976 No. 9 resistor.
3e] PMD Age: New 0 miles
4] Stalling Issues
4a] Do you experience stalling only when hot? No
4b] Does it stall under particular circumstances? (ie hit bump, or on accel) When under 1500 RPMs or 0 throttle.
4c] Does pouring cool water over the IP seem to help with restarting? NA
4d] Is stalling momentary (engine recovers)? no
4e] Does SES light come on when engine hiccups? Sometimes and when it does the truck runs fine when the SES lamp is illuminated.
4f] Does cruise control quit working when engine hiccups? The CC has not worked since this issue began.
4g] Does re-starting seem to reset engine, restoring cruise and power? No
4h] Changes to dash lights or instruments during stalling events? No
5] Running Issues
5a] On cold start, does upper rad hose get hard before engine warms up? Yes
5b] Any bubbles or oil film in coolant overflow tank? No
5c] Any white slime on oil surfaces (dipstick, CDR, oil Fill cap)? No
5d] Excessive white smoke from exhaust on cold start? No

6] Performance Issues
6a] Do you have gauges (boost, EGT) ? No
6b] Maximum boost under load? NA
6c] Have you added a performance PCM (reflash) or Chip? No it’s Stock
6d] Have you changed exhaust / downpipe / crossover? No it’s Stock
6e] Wastegate – mechanical or vacuum (OEM)? OEM vacuum I think.
7] Temperature-related Issues:
7a] Single or dual thermostats? Single
7b] Have you replaced them lately? Manufacturer of replacements? 10,000 or more
7c] Have you pulled and cleaned Radiator and coolers lately? 10,000 or more
7d] Have you replaced the fan clutch? Manufacturer of replacement? Yes new model chevy upgrade with 12 blade fan.
7e] (winter) Have you tested your antifreeze? Good to what temp? Tip top
7f] (winter) Are you using a winter grille cover? NA
I have some screen shots from GMTDScan basic that I will put in my next post.
Thanks in advance.
