History: (Describe how the problem first appeared.)
- What were you doing when it happened? motor swap
- How was the truck running fine before this problem appeared? Fuel System- YES Started right up and ran fine.
- Has this problem ever happened before? Umm- no, 1st engine swap
- Describe any related factors that might be part of the problem. ______________
- Have you checked for DTC (Diagnostic Trouble Codes)? (Y.N) ____ And? ________ NO CODES
Diagnostics:
1] Starting:
1a] Does the engine start? _________NO
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- few sec
1f] Does your glow plug light come on? _________ For how long? _________
1g] Do you see smoke from the exhaust while cranking? What color? BLACK
1h] Does the Service Engine Light Glow during Start/bulb check? YES
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
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? ___________Not now, but I did before the engine swap- hasn't run yet.
3] PMD / IP Issues
3a] Location of PMD (on pump, on intake, remote mounted) remote
3b] Condition of Extension harness (if used) Vendor or Homemade? PMD Cable
3c] Condition of grounds / ground wires to IP / PMD. Check Harness. 0.9 Ohms
3d] PMD Make: D-Tech___________
3e] PMD Age: June 2009
I just changed out the engine and used the existing LP and injectors as they were known running fine. Block was cracked- engined changed for that reason. Engine cranks fine, fires a few and then dies. Cracked every injector and cranked until fuel came out. Scanned repeatedly. Only codes that showed up was when I tried to start after unplugging Optical Sensor and Crank Sensor. Neither allowed to start. Tried both and independently. After those codes cleared, no new codes. Place clear hose on injector return line. Air noted, but does not seem to be replaced by new fuel. I have no known "GOOD" PMD to swap, but I am wondering why a remoted PMD would fail immediately after engine swap when it is a few months old. Truck drove into shop. It seems like there is a "starting" mode that works and a "running" mode that doesn't. Don't know if that makes any sense. Have been cranking with cooling breaks from 5-11 PM with no change. I'm obviously not familiar with the electronic controls of this injection system and seem to think that's a problem. Last thing I checked was pump solenoid and it clicked. I'm baffled. Before I buy another PMD to hope and see I'd like to pick some of your brains.
