At first it would start up and run fine but the tachometer would dip down when I was slowing and sometimes cut the car off. I changed the fuel filter and that didn't change anything but now the car won't start at all unless it has sat for a couple of days. I believe I might have to change the fuel pump, but I'm not for sure. If it does sound like the fuel pump, can anybody direct me to a tutorial or video on how to do it? I'm not a grease monkey but I learn fast so I have a feeling I might be able to do this with the proper guidance. Any help would greatly appreciated and thanks.
Well buddy if I were you I would start out by Seafoaming the car once you get it running. If you don't know what that is, you can search for it. Basically its a can of cleaner stuff you buy at NAPA and run through your brake booster line, and it cleans everything out. After that, your plugs (and O2 sensor) are going to be covered in all the crap you just blew out. You WILL need to replace them.
IIRC, if you buy a Walbro fuel pump (which you probably don't need), it comes with directions on how to put it in. To see if your fuel pump is working, make sure your radio and everything is turned down. You should be able to briefly hear a "hummmm" when you turn your key to the ON position (without cranking).
If you do that stuff, and stuff still doesn't work right, come back and explain whats going on, we will help you further.
