There is a fuel shut off switch (inertia fuel shut off-opens on impact) in the wiring between the fuel pump relay (in the under-hood fuse/relay box) and the gas tank. It may have opened. I don't know where it is located, it may be behind a kick panel under the dash. You may have to ask someone where it is.
The fuel pump fuse is a 20amp fuse, also in the engine compartment fuse/relay box. This fuse and it's wire is the power feed for the fuel pump relay.
This should be in the owner's manual. I found the below on autozone.com, their repair help location:
An inertia switch is used as a safety device in the fuel system. The inertia switch is located in the cab, generally under the dashboard on the right side. It is designed to open the fuel pump power circuit in the event of a collision. The switch is reset by pushing each of 2 buttons on the switch simultaneously (some models use switches with only one reset button). The inertia switch should not be reset until the fuel system has been inspected for damage or leaks.
When the ignition switch is ON , it turns the EEC power relay ON . The EEC power relay provides power to the powertrain control module (PCM) and the control side of the fuel pump relay. Power for the fuel pump(s) is supplied through a fuse link or high current fuse attached to the starter solenoid (battery side). From the fuse link or high current fuse, current flows through the fuel pump relay and inertia switch to the fuel pump(s). The fuel pump relay is controlled by the PCM.
When the ignition switch is turned ON , the fuel pump(s) will operate. If the ignition switch is not turned to the START position the PCM will shut the fuel pump(s) OFF after 1 second. The PCM will operate the fuel pump(s) operate the fuel pump(s) when the ignition switch is turn to START position to provide fuel while cranking.
After the engine starts, the PCM will continue to operate the fuel pump(s) unless the engine stops, drops below 120 rpm or the inertia switch is tripped.
Inertia switch is located Under right side of dash, on heater plenum. Do you hear the fuel pump turn on when turning ignition on? you can hear pump by opening fuel door and put ear against while having someone turn ignition on, another test would be to install a fuel pressure gauge on scradder valve and reading fuel pressure - recommended
Your inertia switch is located in the right hand kick panel at the top, hard to reach with panel on, you can check it to see that it is in fact pushed in, but they sometimes burn out in this position, try using a jumper wire across the connections of the inertia switch and see if your pump runs, if so replace the switch, try the same for your ranger. Hope this helps, let me know
In the fuse box, (under the hood), lower right corner. C1051....if you think its bad, there are others like it in the fuse box you can swap with. If the fuel pump doesnt work, be sure to check the INERTIA SWITCH. I cant tell you how many fuel pumps are replaced because no one checked that switch. If the Inertia Switch is good, have someone rap on the bottom of the fuel tank while you are cranking the engine over, if it starts then, the fuel pump is bad.
Dodge dosent have a inertia switch the relay should have battery voltage on one wire with key on, ground on one wire,and when cranking the car another wire should get power but only while cranking and teh last wire will be power going out to you're fuel pump
