The fuel pump normally only comes on for a second unless the car starts and is running, if the car starts and the pump only runs for a few seconds, then there is a problem with the engine signal to the ecm, ie its not telling the computer that it is running. I dont believe there is a schrader valve on those fuel lines, if there is, chrysler probably put it underneath the intake plenum. If the car will not start, but you hear the fuel pump kick on and off, it could have a clogged fuel filter, or injectors, or even bad connections going to the injectors. They normally are all switched via the ground wire for each injector, so if they are not cycling it could be a bad ecm, or bad connection somewhere in the wiring harness
the ecm controls the initial prime for the fuel pump.make sure the relay is getting the signal from the ecm.the wires near the ecm should be checked for broken,damaged or corroded wires as if the ecm doesn`t get the proper voltage or ground it will not prime the fuel pump for the 2 seconds.
You may want to try to see if the car will start while you spray starting fluid down the throttle body. If it doesn't, the problem may not be the fuel pump at all. There is an idle air control valve bolted to the front of the throttle body that can keep the car from starting as well.
If the car starts with the starting fluid, you might want to change your fuel filter. It's mounted under the car near the passenger rear door.
It helps if you tell what year,model, engine you are working on. Is power at the Inertia Switch? The power comes from the FUEL PUMP RELAY, the ECM only grounds the relay to turn it on. but not knowing what you are working on, thats all the info I have .
are you sure lack of petrol was the reason the car stoped. try leaving the ignition on for a whlie and also turning the ignition on and off and leaving it for 10 second before turning of.this will get the fuel pump working, pumping fuel to the fual rail. and building up fuel pressure again.hope this helps
