Recently changed fuel pump and filter 3 months later car quit at intersection. I pushed it to lot and sat for a while. Then it started and was able to drive home 3-4 miles while noticing I am not getting much power or fuel to the engine. Did it a couple times. Added HEET to gas and now it wont start at all. No fuel making it to engine.

Check for applicable trouble codes? When you first turn the key on, no crank, can you hear the pump run for a few seconds? If you can't hear it, check applicable fuses.

I just wanted to add, if you have that spider fuel system, it is noted for problems.

Hello, I'm Danny.

Yes, Its nickname is the "spider". It's the fuel injection control unit that is mounted in between the upper and lower intake manifold. You have to separate the intake manifold to gain access. I've attached a picture below and circled the "spider" in red. Hope this helps and thanks for using 2CarPros.

Thanks, Danny, I appreciate the answer and can see where the nickname came from. Always trying to increase my knowledge about these systems as I own 3 of them! Thanks again!
