Hi everyone, I've got a '99 Mustang with a V6 and this morning it will not start. Plenty of battery juice, it just turns over without a hint of starting. Don't know if it's fuel related or ignition. It did this about 2 weeks ago but then I came back about 5 minutes later and it started right up like there was nothing ever wrong with it.

Any suggestions on what to look for, test, anything other than taking it to a shop?

I need to get this car running since it's my wife's car and if I can't get it running, she'll want to take my 2001 GT that I keep garaged all the time with only 6K miles on it! HELP!!!!

Well, it finally started without doing anything. Maybe have it checked on a computer to see if there are any errors.

Fuel or fire.

Fuel - fuel pump, filter, hoses, fuel rail pressure
Fire - spark, fuses, plugs, battery, alternator, wiring short or battery connection or ground

Similar problem ,but my exhaust pipe had cracked about a foot from the headers drove like that for about a month then started feeling some resistance in what felt somewhat like air assist brakes on a big rig , a week ago it started missing when accelerating then yesterday on the way to work it finally gave out ,will crank but no start I sprayed starter fluid through the throttle plate .. nothing replaced the coil pack .. nothing ,any assistance is appreciated

Fuel, the engine just started like there was no problem. I'm thinking it's a fuel pump maybe going.

I did check the fuel rail valve and when I pushed the pin in no gas was present. I did the same thing afterwards when the engine started and there was fuel there so something is not getting fuel there when it happens.

BTW, how do you edit a post or can you? I don't see anywhere to do so.

You can edit your post after so many post. Im thinking its 10 posts but not sure.

Ahh, OK.

Might be worth replacing the fuel pump relay.

It may be the problem and that would be an easy fix.....Do you know where it is?
