RE: Car will not start or crank.
Start with basics.....

What's the battery voltage at rest? (should be 12.5) If you are not sure then substitute a known good battery from another vehicle.

What's the battery voltage while attempting to crank? If the voltage doesn't change then you need to look at all connections including ground wires. If it does change then how much and note anything you can hear on this board so we can go further.

RE: Car will not start or crank.
If it won’t even crank, what all have you checked? It may sound really dumb, but I used to make at least one wrecker call a month to put the transmission in “Park.” That said I would start by making sure that the battery is good & that the battery terminal connections are clean. From there a lot of Fords use a remote starter solenoid. If it has one, that would be my next stop. Good clean connections and test to see if you get power at the ignition wire when the key is turned to the start position. If the solenoid is on the starter the same holds true. If you don’t get power to the ignition wire you will need to check to see if the wire is ok, check the fuses, and make sure that the ignition switch is working. There could also be a problem with the “neutral safety switch.” If all of that checks out the starter is the next spot to check. Is it getting power when the key is activated? Is the connection good and clean? Does it have a good ground?

Those are some things that you can check if you haven’t already. I didn’t go into a lot of detail on “HOW” to check them since you may already know how and/or this may already be done. If you need any details, let us know.

If you find the problem, please let us know what it was!

RE: Car will not start or crank.
Sorry I'm posting for someone that does not have internet. I miss understood what he said at first. He is stating that the car is cranking but not starting. He said it is getting fuel but not fire.

RE: Car will not start or crank.
OK, that makes a world of difference but we are still talking about a 26 year old car.

I need to ask where you checked for spark because that's got an old fashion distributor and the cap or the rotor can fail. I suggest you double check for spark at the coil wire and if that's good at least you are narrowed down to cap, rotor, or wires.

If there's still no spark do a close inspection of the small wires to the pick up coil inside the distributor as they are prone to breaking with old age. While you are in there look closely at side play of the dist shaft and possible damage to any moving parts. (fly weights, reluctor, etc) The pick up coil should have a few hundred ohms resistance. If that checks good you are probably needing the ignition module, which is a potted / sealed unit with aluminum on the outside. It's usually mounted on the inside fender well with a round connector on a pig tail.
