I have a 2003 dodge durango. It takes a few seconds to crank and once it does, it immediately shuts off. If I do get it to start, I have to keep my foot on the accelerator to keep it running. If I take my foot off the gas, it stops running. It was sugessted that my battery was bad, which it was, so I replaced it. The problem still occurs. Does anyone know what else I can do? Thank you.

Re: 4urango will not stay running
Check your IAC (Idle Air Control Valve). Also inspect your EGR valve. Check your fuel pressure should be in the range of 25-35PSI. Make sure your fuel filter is not clogged. Check spark plugs and wires

The power to the ignition coil comes from the Auto shut down relay. It also runs the fuel pump relay. When you turn the key on it will read 12 volts, but only for about 5 seconds. The auto shut down relay is controlled by the ecm. Check the power on the coil while cranking the engine. When cranking the ecm will lock on the ASD relay.
It sounds like the fuel pump has failed, I'd start by checking the fuel pressure. Turn everything off so you hear whether on not the fuel pump runs when you turn the key to "on". The pump should run for 3-5 seconds and the stop and it won't start running again, until you turn the key to "start".
hello po442 ,po455,po456 is leak detected possible, check the gas cap , basicaly you have a leak that is larger than 0.020' and smaller than 0.040' in the gas evaporative system use your nose to find this one thanks
how old is your battery? because if it is weak the idle air control solenoid will not sit in the right location thus the vehicle will stall and wont stay running .replacing a weak battery will fix this problem .
