Has a new fuel pump and filter. I am getting fuel and spark. It will run on starting fluid but not fire up. Just wondering what else it could be.

Hi,

If it runs with starting fluid and the fuel pressure is within the manufacturer's pressure specifications, it sounds like it is an injector issue. The fuel isn't getting into the engine.

First, check the ECM1 fuse in the under-hood fuse box. In addition to checking the fuse, confirm there is power to and from it. Here is a link to help.

If the fuse is good, we need to confirm power at the injectors. Each injector will have a pink wire to it. The pink wire should have power at all times when the key is on. Confirm they are getting power and let me know what you find.

Take care,

Joe
