Engine NO START Troubleshooting Tips

Troubleshooting tips: ROUGH DRAFT
1991-93 12v V6
Check engine services fuse in main fuse box.
Check fuel pressure with fuel injection pressure gauge (rent free from Autozone).
Be sure "red stripe" ECU relay with diode plugged into correct relay holder with RED wires near coil.
Fuel pump relay is one next to it plugged into holder with pink and pink-white wires.
You can test fuel pump by pulling fuel pump relay and test for power with key on at socket 30. Now jumper socket 30 pink wire to socket 87a pink-white wire and turn key on pump should run.

Check distributor cap and rotor
Check spark with spark tester and or inductive or direct hook up timing light (tester and timing light will flash if spark going through sparkplug wire.
