Question
i have a 86 300e gas engine it was running then it quit altogether.we did a tuneup checked for compression its good. we are getting fuel and sparkand it still wont start

Answer
did you check your ovp relay 10 amp fuse I would start there your airflow sensor may be misadjusted check for all your connections on your airflow sensor a good way to check is have someone crank on your car while you watch your airflow sensor.chances are it is gummed up it goes to your throttle body youll see it bounce up and down then start chances are you are running too much air around there check your hoses going to the airflow one may have come loose
