This chart identifies only problems pertaining to the fuel injection system. However, before looking for the problem in the fuel injection system, make sure that it is not possibly in another part of the engine, such as in the ignition system. Trouble Cause Correction Engine does not start, fuel pump is not running. Defective pump connections, pump relay or connections.
Check pump connector for good condition.
If necessary, use voltmeter. Check with voltmeter. Repair open circuit. Pump relay shows 12 volts at terminal 86, but terminal 85 has no ground. Do not connect terminal 85 to ground without first disconnecting wire 19 leading to the control unit, otherwise the control unit will be damaged.
