This procedure diagnoses a No Start engine problem. The procedure is based on information from the Ford Service Manual and my personal experience. The numbered steps should be performed in the order listed.
1. Does "THEFT" blink rapidly with ignition key in Off, On or Start?
Yes: Verify key validity
Check Passive Anti-Theft System (PATS)
No: Go to next numbered step
2. Check fuel tank gauge reading. If fuel possibly contains water or condensation from cold add treatment to the tank.
3. Turn ignition key from Off to On. Does fuel pump run for a few seconds?
Yes: Go to next numbered step
No: Perform Fuel Pump Electrical Procedure
4. Does "CHECK ENGINE" illuminate?
Yes: Go to next numbered step
No: Perform the PCM Power Procedure
5. Turn ignition key to Start
Does starter motor crank engine?
Yes: Go to next numbered step
No: Perform Starter No crank procedure
6. Does "CHECK ENGINE" illuminate while engine cranks?
Yes: Check crankshaft position (CKP) sensor
One way to check the CKP sensor is to determine if the fuel pump runs when the starter is cranking. This can be done simply by listening to the pump.
No: Go to next numbered step
7. Check battery voltage
8. Perform TPS Test Procedure
9. Check ignition coils, plugs and wires. Some members have experienced ignition faults with Bosch platinum plugs.
10. Perform Fuel pressure test procedure
11. Check fuel injectors
12. Check compression
13. Check EGR system
14. Check engine coolant temperature (ECT) sensor if not a cold start
