I replaced fuel pump and a couple of relays. We have spark and air. It will run for a few seconds on starting fluid. I can't think of any thing else. Please help!

Good afternoon,

I would start by doing a fuel pressure test. if you can start with priming, you have spark and compression.

Did you use a new fuel pump?

Beyond that you need to get a noid light and check the injectors to see if the PCM is commanding them to flow fuel.

Okay, then you need to check the fuel pressure and the noid light.

The TIPM or the fuse box controls the fuel pump. Check the fuse listed in the diagram for power on both sides when cranking.
