Need HELP!!!!!
 

Here's what's going on. #1 i had to replace my fuel pump relay under the seat...Done...#2 the pump will prime some times and some times it will keep running even after the car is cut off and the key is out of the ignition . I have good fuel pressure going to the injectors but the car does not crank.. Can any one help with this????? Any ideas will help.

i would say that it would be an ignition switch problem, im not sure what year your car is but there were ignition switch recalls on the 89-93 stangs, possibly other years too.

Help
 

My mustang is a 1990. I have the same feeling about it. I tought about it all night and all I could come up with is the ignition switch. I hope this is it..I've never changed it since the recall.
