i have a 99' 2500 pickup k style and i started it yesterday and went about a block and it died. cant get it to start since. fuel pump is good filter is clean and i still can't seem to get it to fire. changed my coil and module and still won't. i heard or passlock sensonr, but the security light goes off like it should after 5 seconds when the key is turned on. If anybody has any ideas please let me know.

 

could it be the crank position sensor

 

Just has this problem and it was the cap and rotor.
But it can be a number of things.
Cam sensor, crank sensor,maybe loss of spark or not enough spark,fuel pressure could be low. Check fuel press. Then spark
Honestly on something like that check for spark then check for fuel if you have no spark then route it to electrical(distributor/cap/rotor)

 

Pm me if you have any more ?'s
