General maintenance: inspect and evaluate the condition of each. When were they last changed?
- Air filter __Replaced_______
- Fuel filter _No idea on last replacement date________
- CDR Valve? __No idea on last replacement date_______
- Coolant – last flushed/replaced at __Never done since I owned it___________
- Oil – synthetic/regular, changed at __10k ago_________
- Batteries – state of charge, (matched set) replaced at ___Good__________
- Battery cables and grounds (removed, cleaned and tightened): ____Couple days ago__________
- Glow Plugs - how many miles on them? __No idea_______ What type? _____________
- Injectors - last changed at ___No idea____________
History: (Describe how the problem first appeared.)
- What were you doing when it happened? ___60 mph on the highway it just stalled out coasted off exit ramp waited a couple minutes and it drove home fine___________
- How was the truck running fine before this problem appeared? ___Fine__________
- Has this problem ever happened before? ___Yes____________________
- Describe any related factors that might be part of the problem. ____Accelerator pedal seems to not work, if I am driving down the road and let off the pedal then get back on the pedal I have to push a lot further on the pedal to get any acceleration or I have to completely let of the pedal and hit it again, sometime I have to push on it a couple times to get it to react__________
- Have you checked for DTC (Diagnostic Trouble Codes)? (Y.N) __N__ And? __No check engine showing______
Diagnostics:
1] Starting:
1a] Does the engine start? __Yes_______
1b] Does the engine crank over? ___Yes_____
1c] Are your batteries fully charged? __Yes_______
1d] Have you removed, cleaned, and tightened all battery connections? ___Yes_____
1e] Does your Wait to Start light come on for a time? How long? __Yes Normal time 30 seconds I guess_______
1f] Does your glow plug light come on? _________ For how long? _________
1g] Do you see smoke from the exhaust while cranking? What color? __No______
2] Fuel Issues (if not running):
2a] Can you hear your lift pump working? __Not sure________
2b] Do you get a steady flow of fuel from the water drain (T-handle) ? __Haven't checked_______
2c] Loosen the inlet line from the IP – is fuel coming out (Lift Pump on)? __Haven't checked_________
2d] Loosen an injector line and crank the engine - does fuel come out? ___Haven't checked______
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) __On intake (FSD heatsink)_________
3b] Condition of Extension harness (if used) Vendor or Homemade? ___Looks ok I greased the connections______
3c] Condition of grounds / ground wires to IP / PMD. Check Harness. __Haven't checked these_______
3d] PMD Make: __FSD_________
3e] PMD Age: ____No Idea_________
4] Stalling Issues
4a] Do you experience stalling only when hot? _Yes___________
4b] Does it stall under particular circumstances? (ie hit bump, or on accel) __No____
4c] Does pouring cool water over the IP seem to help with restarting? ___Haven't tried this maybe after a half minute of it sitting it starts back up______
4d] Is stalling momentary (engine recovers)? __No_______
4e] Does SES light come on when engine hiccups? __No_______
4f] Does cruise control quit working when engine hiccups? __Haven't tried the cruise_________
4g] Does re-starting seem to reset engine, restoring cruise and power? ___Yes______
4h] Changes to dash lights or instruments during stalling events? __Yes_________
5] Running Issues
5a] On cold start, does upper rad hose get hard before engine warms up? __Haven't checked this_____
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_______
5e] Excessive black smoke from exhaust under hard acceleration? __No________
6] Performance Issues
6a] Do you have gauges? ___Boost gauge________
6b] Maximum boost under load? __7lbs__________
6c] Have you added a performance PCM (reflash) or Chip? __No____________
6d] Have you changed exhaust / downpipe / crossover? __Yes______________
6e] Wastegate – mechanical or vacuum? ___Mechanical___________
7] Temperature-related Issues:
7a] Single or dual thermostats? Not sure___________
7b] Have you replaced them lately? Manufacturer of replacements? ___No______
7c] Have you pulled and cleaned Radiator and coolers lately? __No__________
7d] Have you replaced the fan clutch? Manufacturer of replacement? __No______
7e] (winter) Have you tested your antifreeze? Good to what temp? __No________
7f] (winter) Are you using a winter grille cover? ___No________
List and describe any other factors which are not addressed in this checklist. We can’t see, hear, smell, or touch your truck, so the more descriptive information you can give, the more likely it is that somebody can assist you.
Trying to figure out if maybe my PMD or Accelerator pedal is bad or possibly both given the mileage that is on the truck.
Thanks all for your help.:thumbsup:
