Question about 2003 Dodge Caravan
03 Grand Caravan 3.3L. Will not start. Starter does not engage, fuel pump doesn't prime...nothing. Battery is good and has been verified as such. Thought possibly ECM, installed a used one (our key is black so we were told it didn't need to be reprogrammed by a dealer) - no change whatsoever after installing new ECM. All fuses/relays look/test good... Any ideas??

There is not fuse for pump but a relay in the relay block. I do suggest jumping to see if pump turns on. Test voltage from ECM if needed. If voltage is to pump, then pump is shot. If not voltage, relay may be bad

Its normal for the pump to run for three seconds then shut off if the car engine is off. . This indicates that the fuel pump turned on and the pressure did reach specifications. If the pump did not reach pressure the pump would continue to run, You need to check for proper pressure with a gauge. If tthe pressure is ok then you have another issue like an ignition module or crank sensor if applicable. You may have to drive the car with the fuel gauge hooked up to see if you still have pressure when it dies.. I know you said you replaced the pump already but do you have the same issues as before you replaced it. This would indicate which direction you need to go now. If the same then its prabably not the pump.
