ok for all my fellow mustang lovers iv got this car and its got me puzzled pretty good right now ok lets start. Iv got a 84 notch back 5.0 car. when i bought the car it had a early 70's 302 motor in it. well its a 4 bbl motor. the car had a painless kit in it when i bought it and the wiring was done like crap so it burnt up. so now this car has no wiring at all. ok now heres the fun part. i started putting the car back together i put a new water pump ,new gaskets,new coil,wires,plugs,cap,rotor,intake gaskets,rebuilt to carb, i adjusted the valves,its in time have a new coil and for a temp fix until iv got the new wiring iv got it wired to a toggle and push button set up. iv only got this car to fire once and it ran for 2-3 mins. now when your cranking it seems to try and fire but getting nothing. im starting to worry about the motor now. so i figured id ask if anyone knew anything else to check before replacing this motor completly?? if anyone can help id appreciate it.
