1987 Cougar 5.0 no start
i have read all the threads and still could not find an answer.
i have an 87 cougar with an 89 mustang gt H.O.
last week i replaced the heater core ( lots of fun) got it all back together and got it running . let it run for 15-20 everything looked good . turned it off tried to restart and battery was dead, charged battery and car never started again.
Car cranks and when ignition is done quick enough it will start ( with miss fire) then die quickly.
Will not idle.
When the gas is pressed the car cuts out , when i quickly press and let the gas go it gets a shot of gas and keeps running as i pump, but only when i release the peddle.
alt light on dash is also not lit up or on
got spark , got fuel
any guess's would be a help, i would like to say i did all the work on it instead if taking it into a shop and paying
