If he hears the fuel pump run, that means the inertia sw or relay isnt
the problem.. still might be no pressure, however.
Assuming 5.0 here as he says he 'replaced coil'
- dont worry... the coil replacement wasnt totally wasting money, open
frame coils have a definite 'lifetime'.
(get this in your heads kiddies!)
What does your tach do when you switch key on?
- tach bounce with key on means coil has power through it, DOES NOT mean
coil is GOOD, could still be shorted or arcing internally but it's
What does it do while cranking?
- Tach bounce while cranking means there is a switching signal from the
distributor. Could still be 'off' time but there should be some
indication of firing.

Stored how long? Gas ages, you know.. esp if you havent used sta-bil or

Adjust cranking gas flow.

With no luck there.. wait a half hour or so and try with your foot to the

Check a plug, if wet, suspect Fuel press reg, or ECT sensor.
