hi, i have a 92 s10 with the 700 tbi throttle body and i can't get the motor to start. i loosened the gas connector at the inlet and turned the ignition on and i got plenty of gas coming out of the line, and i removed one of the spark plugs, put it to ground and i got spark. could it be the fuel injector causing the problem. there seems to be alot of gas dumping into the throttle body when i try to start it. thanks in advance
