okay...i posted this awhile ago, but now i now whats going on a little better. About a month ago, my dad was driving my car and it died on him. So i posted a topic and the bestt suggestion was the fuel pump. The whole reason I posted was cause he took it to a mechanic who could find absolutely nothing wrong with the car. So after a brief description someone said it was an overheating fuel pump.after driving it around for a month without a single problem, it died many times today. I was leaving school and it died. so i start it back up and it dies again. so i let it sit for a minute or two and crank it up and it works...for a minute. I get to the next level of the parking structure and it dies again. i restart it and it dies on starting again. so i get out and pop the hood. I noticed that the fuel pressure gauge was bouncin around a bit. then i waited and started it up and got to the stop sign before it dies again!!! so i try to start it and it dies again. After a few minutes it fires up and i made it home. After the few deaths at the stop sign, it ran home (which is pretty close- couple of blocks) perfectly. Also, it was early and i was not driving the car alot, so i dont think the fuel pump is overheating, although i am not saying that the pump is good either. description of how it died. It started when i was attempting to leave the parkining garage. when i gave it a little gas to go around a corner(not mashing the pedal, pretty normal driving) it seemed to cut out for a second, then jump forward. next thing i know check engine light comes on and the car starts to rev itself down. once the light comes on, it is going to die -> i tried to keep it from dying by revving it, but as son as i stop, the revs dropped real fast and the car dies. and like i said before, i had to wait a few minutes to restart it or it would die again. Also, the check engine light does not stay on, it only comes on when it is going to die, once it is restarted, the light is off....until it is about to die again. This is a 96 cobra with a few basic bolt-ons. i do have o/r bbk h-pipe and there is an exhaust leak where the driver side header meets the pipe. it is not a huge leak...and i dont think a leak would do this. I could be wrong, but does this sound like anything to you guys.> i am gonna fix the leak soon and maybe get a new fuel pump, although i am not sure that is the problem cause i only drove it for 5-10 minuutes I then parked it for an hour and i get back in to leave and thats when the shit started. thanks foor any help.

hm, could be several things.. when i had my leak.. it was throwing the 02 readings off... and was killing the car.. if your fuel pressure is dropping.. it's probably the pump

If it's the pump and you make it to San Jose I can help you replace it. It's pretty easy. Just make sure that you have like 1 gallon of gas in the tank. Otherwise it's a bitch to hoist it back up. I put in a Walbro 190 lph and it didn't take long. I have to replace mine with a 255 lph next friday. If you want to meet me at my friend's shop, we can use the pit or maybe the lift if it's not in use, to do yours. Let me know.(408-590-8919)-Aaron

This may sound a bit weird...but check your brake booster/master cyl/ABS pump set-up. I was having the SAME exact problem with my 97 Cobra about a year ago; car would die coming up to stop lights, run like sh!t in general, acted like a bad fuel pump. Car only had 27,xxx miles on it. The DEALER went through the car, from head to toe...ended up being my ABS pump. Talk about a goat rope from the dealer- anyway, THEY changed the fuel pump, regulator, fuel pump again...then finally got smart and checked out the brake system. It was starving air off the engine, in turn...making it run like crap. I bet each and every time this began to happen..your check engine light never came on.

For the 100 dollars that a pump cost I say it is worth a shot.
