Will start with either, will run won't start without either. Fuel pump works, getting spark, new battery. Cranks won't start.

Good afternoon,

If the car runs with starting fluid, and the fuel pump runs, you either have a bad fuel pump, ECM or wiring issue.

You need a noid light to hook on 1 injector to see if the ECM is commanding the injectors to fire.

Chances are, you may need a fuel pump.

Does the check engine light work with the key on?

I attached a wiring diagram for you to view of the fuel pump.
