hey i just got my first rx-7, it is a 87 n/a with 95000 miles on it..the car turns over but will not fire...i have checked for spark and it is good, but the fuel lines are not pushing fuel,the gauge says E even tho i put fule in the tank could this be a wireing prob,bad fule pump,a fuse,ecu or some thing like that?? any advise will be helpful
