So i posted something about this a while back and i got some ideas leading to the igniter but thte part is sooo expensive and with rent coming up i dont see me doing anything. I took my car to school and for 2 phases we tried to figure out what the problem was, we hooked the car up to all the scanners and scopes available, when the car was running the spark line and kv was normal and it just stalled out of nowere. We checked for fuel, (going back to the for basics-spark fuel and compression) when we went to go chek for the spark after everything the teacher just pulled the spark plug wire out to see if the spark jumped and shure enough we had spark, so we left it running like that to see if we lost spark before the engine died again and we left it there for about an 1hr and it ran just fine. i ran the car for 2 more phases and here we are with the same problem again. ANy body have any ideas what it might be? thanks..

no i eventually ran out of gas from testing it 6 weeks. I used gas from the clip cars in school to give me some fuel. I checked the fuel pump, checked regulated pressure dead head and the pump was fine. so that was ruled out as well. yea im not quite a mechanic either, they like to refer to us as technitians..lol. when we cant even fix our own cars. But anywasy cant be the fuel because i havent been back in vegas with the celi in quite some time, im currently living in phoenix for school. Have fun in vegas by the way
