1987 Lincoln Town car no-start!!.

Hey guys, i have a 1987 lincoln town car with a 5.0. the other day i noticed it was idling weird like up and down, then after that, it started stalling. i would start it go 5 mi with it, it would stall and not start back up for bout an hour, then it would start and stall again. Now it wont start at all it wont fire. we put gas in the intake and still wont fire, there is also a faint spark once in a while. Any help.

Maybe a bad coil pack? You could try using a test light on the harness (not the spark plug wires) of the coil pack to see if there is any spark signal. Also maybe a bad MAP sensor, here's a procedure to know if your MAP is working fine.

Best regards,

Oscar.
