My first post here, been reading and enjoying the info for quite awhile and now I need help

On the way home yesterday I noticed my fuel pressure dipped down to 4 (gage + red idiot light less than 5 psig) going around a corner then came back up to 14. I thought that was odd. My tank was low but still well above an 1/8th and no light. Today on the way to fuel it up down went the fuel pressure and it died. Got fuel and fired back up and now I notice no buzz when I turn the key on. It fires right up but takes what I think is a long time to build pressure, 2-3 seconds instead of popping right up to 14.

Weak LP and time to replace and/or do I have more issues. No check engine light

Thanks Scott

Welcome to DTR.

Dodge Fuel Level Senders are notorious for leaving folks stranded with no fuel when the gauge still reads over 1/8 tank.

Try adding keeping the fuel level closer to 1/2 tank.

You might have air trapped in the gauge line.
It should work it's way out.

Keep an eye on the fuel pressure, the lift pumps have a baaaaaad reputation also.

Thanks. I know better to let the tank get that low but it was circumstance driven. I do not hear the fuel pump when I turn on the ignition and that is part of my question

do you have a factory lift pump or have you changed to a frame mounted? does the fuel pressure gage move at all when you turn the key on? have you tried just bumping the starter without starting to let the pump run ?

If you're seeing above zero pressure, then your lift pump is working.

Do you have a mechanical, or electrical FP gauge?
