The Diagnostic Checklist:
Please fill out to best of your knowledge.
1. Describe the problem you are having in detail:
February 25, 2010
After changing the PMD module to a remote FSD Stanadyne ‘GREY’ 36976 with a resistor number 6, 7, 8, or 9 the vehicle was running rough when started... a miss type of feeling which left shortly after some acceleration. The vehicle was shut down after 3 to 5 minutes of running
Two days later the truck was started again and it seemed to run fairly well, plowed at a speed slightly above idle for about 5 minutes when it was losing power and died.
The first attempt at restart was not successful, wait about a minute retry and it restarted after about 35-45 seconds of cranking.
Then she plowed another 200 feet with the throttle to the floor and the engine barely… running like fuel starved.
She stalled again and restarted after a short wait. The throttle seemed to have little or no effect on engine rpm. The power band from the throttle seems to be nothing, hesitation – long- or full acceleration.
Went about 2 miles at about 15-25 mph and going down a long grade put it into low gear the engine rpm was varying between an engine braking and an accelerating type of noise. (A FUEL –NO FUEL delivery sense of feel.) Towards the end of the downhill grade rapid actuation of the throttle showed little or no difference.
Stopped and began a slow, 3-8 MPH uphill drive way with some power at the bottom and wondering if it would stall before getting to the top.
More stalling on flat with the engine barely running, in reverse gear, automatic, the throttle to the floor … after 15-30 seconds the RPM’s increased the vehicle moved a few feet, and then stalled again……
The throttle seems to have no correlation to engine speed at some times.
2. Year of truck/engine. Truck 1997 .. engine replaced @ 40,000 ?
3. Odometer reading (indicate miles or kilometers). 75,000 miles
4. Indicate the model number on the Injection pump (starts DS4 or DB2......). ?____
5. Indicate if you know if it’s a K 3500HD.
6. Do you have an EGR on the engine? (An F engine code 8th VIN digit)
7. Air Filter condition (visual check). Clean
8. Fuel filter condition freshly changed.. less than 200 miles.
9. Location of PMD/FSD? Fresh mount less than a week old behind bumper).
9a. If remote mounted, six foot wiring harness Purchased from Southeast Power Systems new Grey Stanadyne 36976 with # 6 or 9 resistor.
9b. Indicate the location and condition of the FSD/IP grounding wire. On the pump / I did not remove check or clean it.10. Outside Temperature (C or F). __30F °
11. Service Engine Light while running?- usually off
11a. Service Engine light does glow during start/cranking/bulb check: Yes
12.Have you scanned for engine codes? No
12a. List exact results on engine codes.
13. Condition of Battery terminals (yes removed, cleaned and tightened).
14. Known condition and age of Batteries. Charged and pass a load test
14a. Are batteries a matched set of same age? Same age
15. Condition of Major Grounds (removed, cleaned and tightened)
16. Does engine crank, or "turn over"? yes
16a. Does engine start and run? Yes most of the time when not stalling
17. If engine does not start- Crack injector line: do you have fuel? n/a
18. Does your Wait To Start light come on?YES
18a.Number of seconds WTS light is lit. about 20 to 30 to cycle before cranking19. Engine Cranking speed (if you have an accurate tachometer). XX
20. Are you experiencing Stalling? WOW yep
20a. Describe the event (upon startup only, down the road, hit a bump, etc...)Please note above.
20b. Do you notice loss of dash or instruments? At times the dash/ gauges are not functioning correctly21. Check turbo inlet and air filter for obstructions. No obstruction
22. In a no-hot start, pour a bottle of room-temp water on the injection pump. Does it start now? Not applicable at this temp or time
23. Lift pump test - Describe results. Fuel at “T” ... new lift pump
24. Upon cold start, does the radiator hose get hard quickly? Have not checked25. Upon cold start, do you have excessive white smoke?No
26. Do you have excessive cranking time before the engine starts? Not usually - only on a stall situation 27. Have you used the block heater? Does it affect engine starting? (only try for starting problems). Have a block heater and do not need it to start at this time
28. Are all glow plugs in proper working order? NEW glow plugs
29. During hard acceleration, do you have excessive black smoke? Not lately
30. Do you have any unusual exhaust smoke issues? Not at this time
31. Turbo check out - Pass/Fail Not completed
32. Indicate fuel that you are using: , #2 Diesel,
32a. If running Veggie Oil fuel setup, indicate details of your conversion (homemade or packaged system). n/a
33. Are you using any fuel additives? If so, please list. Some two stroke oil was added to the last tank of diesel34. Upon unscrewing fuel cap, do you have a large vacuum formed in the tank? No
35. Do you have any service history available that might pertain to the problem you are having? NO
36. Please indicate any modifications to the vehicle that might help us diagnose better. Led to indicate power to lift pump
