Turns over one time and stalls. Ran fine last time it was driven, a day ago. Changed batteries, same starting issue. Is this a crank sensor issue? Truck has 450k miles on it. It is a five speed. Thanks!

Does it have spark while cranking? Try a spritz of carb solvent (or equivalent) into the throttle body, does it fire-up briefly?

Check to see if your truck has an Ignition Ballast Resistor. Its is a ceramic piece with two or four wires connected to it. usually on the firewall. Costs about $10. When these go out, the engine will crank and start briefly and then die. I always carried a spare.

Those were long gone by 1998.

Not a key skim issue? Not trying with a non-oem key? Also not applicable if not equipped. It was quite the learning curve to figure out the skim system in a 02 Jeep WJ when it failed. I thought it was fuel pump, battery, etc.

A SKIM key problem should light the security dot on the cluster (#25):

Always check fault codes first:

1998 is too old for a SKIM key. But it could have an anti-theft system.

An engine needs 3 things to run. Spark, fuel & mechanical (compression/timing).
It may be important to use OEM parts. A sensor specified for your application shouldn't have the wrong terminals(!)
Crank sensor does spark. Cam sensor (distributor) times fuel injector sync to #1 TDC.
Are the spark plugs wet with fuel or black with carbon? Any fault codes?

While I have the utmost respect for Walt, I THINK he meant 4 components. Air, you gotta have air, man! LOL Just busting your chops a little bit, Walt.

You make a valid point, chuzz. I've always assumed air as a 'given'. I suppose that it doesn't have to be the case.

Not if you have rodents like mice and chipmunks around. For some reason, they like to build nests in air filter housings. I've looked at a lot of old cars that have been sitting for years and found a LOT of acorns and hickory nuts inside the breathers, along with leaves and grass.
