wldstng from Arkansas ,1999 Mustang

I am the owner of a 1999 White convertible. It's not perfect and that's why I'm here. I will look in the forum for my car's problem - it will not start. It cranks; no fuel pressure -- if you shoot starter fluid in it the car will sputter as if it is getting fuel but will not start. This has happened about three times in this month. After it sits for a couple of hours it cranks and starts as it normally did when I first got it years ago.

I have replaced the starter relays and the fuel filter and purchased a fuel pump but do not believe the pump is the problem as it nevers fails (or stumbles) after it starts.

I do not know anything about the ignition module that someone has indicated may be the problem. What are your Soluations that I might investigate.

Thanks from the newbee.
