hello, im hoping somebody has run across this before. i have a 91 daytona na that i use for circle track racing. my problem is when i go to start the car, it will start up and run for about 5 seconds and cut off like its only running off of the fuel that gets pumped into the throttle body when you first turn the key on. so ive messed with it for quite a while and figured out it is not getting fuel after the initial prime. i am getting fire all the way to the injector, i can see the injector is working until it runs out of fuel in the tb, ive tried a different injector, fuel pressure regulator, and even the little wiring harness for the injector in the tb. ive also notices that once the car starts, the fuel pump does come on as well. this has completely confused me and i have no other ideas to try and i have a race coming up next weekend. has anyone ever come across this problem before? thanks
