ok..we need to know a few things,,

does it have a spark on the plug wires?

will it fire with a prime?with starting fluid or a little fuel poured into the throttle body?

how much fuel pressure does i have?

thanks

Customer: replied 1 year ago.
has spark on plugs not sure about pressure and no will start but it putts putts then shuts down
Expert:  Tim's Auto Repair replied 1 year ago.

ok

sense it did start with the prime,we know it isnt getting fuel.

you need to test that fuel pressure,these must have no less than 55psi at all times.

i would think the fuel pressure is low from a bad fuel pump
