fuel pump problems
I have a 96 ram 4x4 with a 5.9 in it, today i put a new fuel pump in it and still no crank, I have ohmed out the fuses and relays they all seem good. What else could be wrong. I feel like its not getting power bc i changed the tank slap full of gas and when i turn the key the fuel level should go all the way up, but it doesnt PLEASE HELP thanx

i have tried swapping the relays to no prevail, Also the last time the dodge ran i was jumping off my wifes vehicle i wonder if i might have gotten a problem from that like maybe through the dist., but that still doesnt explain the gas gauge, which has never worked, tomorrow i will check to see if i have fire

yes the other gauges work, when changing the old pump i noticed that the board for the float looked burnt, or worn out over time so i thought the new pump assembly should work, another thing i cant hear the pump come on, can you usually hear the pumps or are they usually quiet, i have never paid attention to it before, I can however hear the relay click on after i turn the key

at ignition on, the pump should come on for 3 seconds? or so, then turn off if there is no engine-rrunning signal from the crank position sensor. it should make a whining noise that you can hear. the right way to check the fuel pump is to check pressure at the rail with a gauge. should be about 49 psi. a low tech way is to depress the schrader valve and if fuel squirts out at 49 psi and hits you in the eyeball, then its good. cover the port with a rag, catch any spill, do not smoke!!!
there is a MAIN fuse in there somewhere. might be called fusible link. also an IOD that's important.
