Check the compresion in all cylinders 100 psi (compression good) check the spark -check the fuel pressure.30 psi at gauge with switch on.(if no keep pressure with switch off injectors or fuel pressure regulator are bad
check the signal to the injectors (get little injectors tester at autoparts) if no signal check the ground to the injectors black wire
or the other wire (computer)= good signal to injectors and good fuel pressure and good spark (defective injectors)

does your alarm system go off, and result in it not starting???
SOURCE: 98 dode ram wont crank no spark
May have no spark due to a bad crank sensor, which is responsible for spark when it gets a pulse through the cars' computer.

YOU NEED TO CHECK DARK GREEN/ORANGE WIRE AT IGNITION COIL WHEN CRANKING ENGINE FOR POWER..IF NO POWER,SHUTDOWN RELAY IS NOT BEING ENERGIZED..THIS ENGINE ALSO HAS CAMSHAFT POSITION SENSOR ON END OF CYLINDER HEAD..ENGINE CONTROLLER NEEDS CAM AND CRANK SIGNALS TO ENERGIZE THE SHUTDOWN RELAY..UNPLUG CRANK SENSOR AND CHECK VOLTAGE ON ORANGE WIRE..SHOULD HAVE APPROX 8V..IF NOT..UNPLUG CAM SENSOR AND SEE IF 8V SUPPLY RETURNS..IF NO POWER TRY UNPLUGGING VEHICLE SPEED SENSOR LOCATED IN TRANS HOUSING WHERE RIGHT SIDE AXLE COMES OUT OF TRANS..IF 8V RETURNS..THE SPEED SENSOR IS SHORTED INTERNALLY..THESE 3 SENSORS SHARE THE SAME 8V SUPPLY CIRCUIT..WITH SPEED SENSOR UNPLUGGED,PLUG CRANK SENSOR BACK IN AND TRY TO START ENGINE..HAVE SEEN THIS SAME PROBLEM AT WORK RECENTLY
