Stall while driving. Replaced fuel pump and filter. Now it won't start at all. Just turns over.

Hi,

Based on the symptoms, it sounds like either we lost fuel or ignition spark to the engine. What I will recommend first is this. See if the engine starts for a couple of seconds using starting fluid. If it starts and then stalls, we know it's a fuel-related issue. If there is no change, then I need you to check for spark to the plugs. Here is a link that explains how that is done:

Also, I strongly recommend checking to see if there are diagnostic trouble codes stored in the computer. This vehicle has an OBD1 system. It doesn't require a scan tool to retrieve codes. All you will need is a short jumper wire or even a paper clip.

Here is a link that explains how to check for codes:

This is where I suggest starting. If we do these things, it will narrow down the circuit the issue is coming from.

One last link. Here is one that explains the most common causes of a crank no start condition:

Let me know what you find or if you have other questions.

Take care,
