Q: Car oftentimes doesn't start, when it finally starts it doesn't stay running.
ok, my car has trouble starting, and when it does start, it doesnt like to stay running. at first i thought it was a no fuel issue, so i replaced my fuel pump and filter. still wouldnt start so i replaced my ignition module and replaced the crank sensor. im getting fuel, getting spark. when the car would finally start, it would stall at around 25 mph and not start again. so i replaced ecu, now it wont start again, i have no clue what to do next. what do you think that could be causing this issue
