    endless fuel issue.

    so a few months back my car started running like crap.
    knew it fuel or air so I started with fuel, then air.
    at this point this is what I've changed in the last few months.
    -injectors
    -both fuel pumps
    -fuel filter
    -AFM
    -ignition coil

    after a while I finally gave in and took my car to my local shop, he diagnosed it and told me it was my external fuel pump and my ignition coil (coil was for a starting issue).
    so I changed both, and nothing changed. I go back and explain and I get "well, it might be the other pump". I payed him to diagnose the issue and I'm getting guesses and maybes. I CAN DO THAT FOR FREE. this is why I just do stuff myself. anyways, I changed the other pump today, and still nothing.

    when I give it gas the RPMs will go up, then start to drop. if I don't start to give it gas again it will just cut out and die. the shop said the pressure from the FPR was fine but when I went back and started getting guesses and maybes he mentioned the FPR. so I'm going to check the pressure myself and probably change it.

    SOOOOO, assuming I change the FPR and it doesn't change anything. is there anything else it could be? I truly don't know what to change next. I've gone through hundreds of threads at this point and I'm so stuck and frustrated. all I want to do is drive my damn car places but instead it sits in my driveway and I change stuff on the weekends hoping I'll solve the issue.

    last thing, it go to where it is out of nowhere. it was running not so great, but I was still able to daily it to work and stuff. then one day I was driving and it turned off when I came to a stop. wouldn't start so I towed it home. it was a blown fuse, I think 10 or 11? one that controls the starter and fuel delivery. I got it to start but now it runs terrible. It was really low on gas so some said I blew the in-tank fuel pump. but that has been changed and here we are. what happened all of a sudden when my car died that day?
    please. please help me.

    link to how it runs.

    You mentioned two out of three components for running well. The third and equally important is air. You need to check for vacuum leaks and a functional AFM.

      I got a rebuilt AFM from the guy on here that does them. popped it in and I noticed a difference but I had already started running into other problems so it didn't help too much. a vacuum leak would only cause minor issues though right? If you listen to the video its really bad. If you watched the video and hear how bad it is and still think that could be it thats what I'll do next. thanks for your input man.

        I suggest going over things for now

        Swap back in old AFM
        Check Spark plugs for fouling/ proper gap
        See if your distributor / rotor isn't on its way out
        Check coolant temp and o2 sensor
        Check injectors just in case, you never know
        The usual vac leaks
        See if the fuel filter was installed in the right direction lol
        Make sure the IG coil was wired properly
        try swapping DME's
        Check compression #
        Fuel pump relays, fueses etc

        I know thats not much help, but doesn't hurt to double check things.

          Find a friend and start swapping known good parts like the DME, TPS, CPS, and such.
          At least cross those off the list.
          Check the things mentioned above me as well.

              thanks guys, thats a lot of stuff I didn't know to check! I've never messed with most of what was mentioned so it might take me a while. but hopefully I can find a resolution during the process.
              thanks again r3v.

                Have a shop run a proper smoke test before you do anything else.
                The car makes it possible, but the driver makes it happen.

                  Very wrong! A smoke test will save you a lot of headache.
