1996 mustang gt immediately dies?

I'm looking to buy this gt 5speed but when we go to start it up it just dies. We can rev it a little but it won't idle. We disconnected the alternator thinking maybe a short but no luck. The original catetaker is nolonger around so we can't ask him. Does anyone else have this problem? If so help me out because i'm going to get this car for pretty cheap if it's a quick fix

Most times when you have a Ford that won't idle right it is the air by pass valve, they carbon up and need to be removed and cleaned. It could be a vacuum leak also.

Its a ford. Thats what's wrong with it.

Bad air idle motor look it up on the internet simple fix

Well it looks like you have no frickin clue about cars. You never disconnect a battery cable on a car with a computer. It puts the alternator into maximum output which can be over 17 volts. With out the battery as a ballast the higher voltage spikes can burn out the ECU. How do the timing marks look? Did the belt jump? You need a mechanic to check it over before you waste your money. You get what you pay for and sounds like you're about to pay for someone else's problem.

Might be the ignition coil or fuel pump, possibly it might be the crankshaft position sensor
