Preliminary Checks

WARNING: This page does not describe the selected car, but rather 24 other vehicles, including the 1997 Ford RV Cutaway, 1997 Ford Pickup, 1997 Ford F-Super Duty, 1997 Ford Econoline, and 1997 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

Visual engine and chassis inspection.
- Loose or leaking fuel supply lines.
- Kinked or blocked fuel supply lines.
- Massive fuel or oil leaks.
- Coolant leaks.
- Electronic connectors and wiring (particularly camshaft position and injection pressure regulator).
- Pinched or open MAP sensor hose.
- Pinched or open intercooler hose.
Check engine oil level.
Check for intake or exhaust restriction.
Check for sufficient and clean fuel.
Check electric fuel pump pressure. See FUEL PRESSURE .
Perform KOEO on demand self-test. See appropriate SELF-DIAGNOSTICS - DIESEL.
Retrieve Continuous Memory DTCs. See appropriate SELF-DIAGNOSTICS - DIESEL.
KOEO injector electrical self-test. See FUEL INJECTORS .
Using scan tool, monitor:
- V-PWR
  
  Check system voltage. If system voltage is low, check battery, charging system, and powers and grounds at PCM.
- RPM
  
  Low RPM could indicate a starting/charging system problem. No RPM with engine cranking could indicate a faulty CMP circuit.
- ICP
  
  A minimum of 500 PSI is required before injectors are enabled. No or low oil in reservoir, system leakage, injector "O" rings or faulty IPR could cause pressure loss.
- Fuel PW
  
  Even though a 1-6 millisecond fuel pulse width is shown on scan tool to be sent to IDM, it is possible that IDM did not get signal, due to a fault on CID or FDCS circuits or a faulty IDM.
Check glow plug system operation. See appropriate SYSTEM & COMPONENT TESTING - EEC-V - DIESEL.
