Good evening,

Does the engine turn when you try to start or does it do nothing?

If it cranks over, you need fuel pressure, compression and spark. I attached some guides for you to follow.

I attached a wiring diagram of the starter system as well.

Okay, you need to have the fuel pressure tested and see if there is any spark.

You can rent a tester at a parts store for the testing.

FUEL PRESSURE:

Ignition "ON" Engine "OFF" .................... 40.5 to 47.0 psi

With Regulator Vacuum Applied [1] ..... 3.0 to 10.0 psi Less than Ignition "ON" Engine "OFF"

REMARKS:

[1] May be checked with either of the following methods.

With Pressure Regulator Vacuum Line Attached at normal idle speed.
Ignition "ON" Engine "OFF" with 10 Inches Of Vacuum Applied To The Pressure Regulator.
