Car will not start after replacing fuel pump

Hi and thanks for using 2CarPros.com.

If the check engine light was flashing, that indicates a misfire. First, scan the computer to determine what codes are stored in the computer.

Next, confirm the new fuel pump is producing the proper amount of fuel pressure. Here is a link showing how it is done:

https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator

With the key on and engine off, the pressure should be 48-55 psi

If that checks okay, next you need to check if there is spark to the spark plugs. Here is a link that shows how:

If there is no spark, suspect a bad crankshaft position sensor. Picture 1 indicates its location.

I realize you indicated little knowledge, but here are the directions for sensor replacement if you decide you would like to do it. Starting with picture 2, all pictures correlate with these directions.

Hi again. There is a good chance the engine was flooded when you were trying to start it prior to finding the wire issue. See if it cleans up and starts running better. If it does not, you may have to replace the spark plugs.

Here is a link that shows in general how it is done:

One other thought, make sure no engine vacuum lines are disconnected, damaged, or pinched shut.

Let me know what happens.

Take care,
Joe

Honestly, fuel would have gone to all cylinders. Therefore, it could have fouled any of them. Again, make sure there are no vacuum leaks. Also, if the engine has a misfire, the check engine light should have come on. If you scan the computer, it should indicate which cylinder has the misfire.

Let me know.
