Intermittent fuel pressure drop, to 5 psi, on a stratus 2.4l 1996

your showing 18 drop in fuel pressure and probably drops more ----suggestion would be test and check fuel pump and filter for failing or power drop [module] to pump

Fuel pump intermittent, check for fuel pressure before dropping the tank to renew pump.
Otherwise check electrical connection at battery, and make sure you do not have an open circuit.
Loss of connectivity could cause this issue, failed fuel pump sometimes work, but are not reliable.
You should see 30-45 psi at fuel rail, and the regulator should bump pressure 5 psi when reving the motor. Higher pressure indicates failed regulator.

This could have several problems. #1 Fuel pressure due freezing water in fuel lines add thermal aid or rubbing alcohol . If you have access to a pressure gauge there is a service fitting on fuel rail that you can test pressure while driving and see if the pressure is gone when car dies this could lead to fuel pump electrical or more restricted lines. #2 intermittent sensor failure Mopar uses 2 sensors to control spark and fuel lose one could lose spark lose the other lose injection with a scanner they call it C/C sync ok (cam/crank) if no then check for each parameters for display.# 3 relay controls ASD and FUEL pump for voltage drops.

sounds like you need to replace your fuel pressure regulator.

2004 Ford 150 5 4L Stall No Start P0191 Fuel Rail Psi Sensor P1233 Fuel...

have a fuel pressure gauge hooked up to it to see if the fuel pump is going bad..sometimes when fuel pumps start to fail the pressure will drop intermittently...this test willl find out if that is the cause

check for 12v constant at your fuel pump if you are not getting that replace your relay.
if you are getting 12 volts at your fuel pump the fuel pump is possible to run tuel it gets warm then shut down to a lower rpm I would then replace the fuel pump

Don't have access to actual pressure required at this moment but I will tell you that 12-20 psi is definitely not enough. Your probably looking at a minimum of 50-60, and as much as 90-100 depending on what engine. A replacement for a 3.3.L at autozone is rated at 90-100 psi. I'd spend the money on new pump & filter at same time.

Once a filter plugs its pluged. You drop that much pressure its time for a new fuel pump.

No it is a fail safe. When your oil pressure drops below (on most cars) 30 psi your computer will shut your fuel pump down until you either let it sit for a while and it resets or until oil pressure builds again. Sorry!
