Fuel

HI
Check for power at an injector on dark green/orange wire. Have you tried checking power at fuel pump relay? Also dose ASD relay click when key is on?Do you have a way to check pressure?

Bad pump. You already made the observations that provide the clues. Has spark means the circuit that cause 90 percent of the problems is working properly. No hum for one second after turning on the ignition switch clinches it. Sometimes banging on the tank will get it going. That works most effectively when a helper is cranking the engine at the same time so there will be power to the pump motor.

It is REAL common for GM pumps to quit while driving, but Chrysler pumps rarely do that. They usually fail to start up due to worn brushes in the motor.
