DELPHI EFI Function Test Fault Codes Example of Diagnostic Display (0) One second pause (1) Fault Code 0107 One second pause (0) )XQFWLRQRIIXHOV\VWHPLVWRSURYLGHVXIїFLHQWGHOLYHU\ of fuel at system operating pressure of 39 psi ± 3. If an engine starts hard, or turns over but will not start, it may indicate a problem with EFI fuel system. A quick test will verify if system is operating. 1. Disconnect and ground spark plug leads. 2. Complete all safety interlock requirements and crank engine for approximately 3 seconds. 3. Remove spark plugs and check for fuel at tips. a. If there is fuel at tips of spark plugs fuel pump and injectors are operating. b.
If there is no fuel at tips of spark plugs, check following: 1. Make sure fuel tank contains clean, fresh, proper fuel. 2. Make sure that vent in fuel tank is open. 3. Make sure fuel tank valve (if equipped) is fully opened. 4. Make sure battery is supplying proper voltage. 5. Check that fuses are good, and that no electrical or fuel line connections are damaged or broken. 6. Test fuel pump module operation as described earlier under Fuel Pump.
