Bulletin:
Recently replaced the fuel pump and at present the fuel system is non staying preasurized. Start the truck and the fuel preasure is normal, but when y'all shut the truck off, there is absolutely no preasure in the system. Besides since replacing the pump the cheque engine calorie-free comes on, flashes code for O2 sensor stuck in the rich position. Replaced the O2 sensor but however have the aforementioned trouble with the check engine light. The truck runs great, but information technology is hard to kickoff after it has been sitting for a while. Is there a check valve in the pump that may not be working? Or could I accept been givin the wrong pump? Other than that, at 221,000 miles she runs like a summit. Any help would be greatly appreciated guys. Thanks

If the system is not staying pressurized and you are having trouble starting information technology one or more injectors are probably leaking down. Pinch off the fuel line between the fuel rail and the pump, if yous are still losing force per unit area you know the problem is probably with the injectors. If yous are confident you know what yous are doing you could pull the fuel rails and all the injectors out to see if they baste with the system pressurized and the truck off. If a injector is bad your best bet is to supersede them all because the others are close behind.

Thanks guys for responding to my question. I idea virtually leaking injectors, but I had to save the pressure off the system before I removed the old pump. Since replacing the pump the organisation will not concur any pressure when the truck is not running. I mean immediately after yous plow the primal off, all of the force per unit area is gone to zero. For it to lose that much pressure level that speedily, all of the injectors would have to be stuck open don't you think? And if the injectors were leaking wouldn't it run rough when yous started information technology from excess gas in the cylinders? It is hard to beginning after it sits, only when it fires up information technology runs very smooth. Something tells me that there is something not right with the fuel pump. Somewhere in the arrangement there must exist a check valve to continue the fuel from running back into the tank. Could it be in the pump itself and not closing? Just some thoughts.

Then information technology is a bad pump and I bet it is not a Chrysler pump.
The valve is in the pump.
The Chrysler ones are the all-time, in this case, to use.

Thanks guys, I'll take the pump back and get some other one. No it's non a Chrysler pump. I got it from Pep Boys. It's a carter pump so I assumed information technology was a quality part. Maybe not. I'll bandy it out and let you know. Cheers so much for your help.

could the problem exist? i was told maybe the fuel

The cheque valve for the fuel system is in the filter regulator on top of the pump. Did you go a new one with your new pump? you should have. and a new sender for your fuel approximate too. I just got a new pump from NAPA for my 94 V6, same brand as origional inculded the complete assy. pump, sender unit and filter/regulaotr

Aught incorrect with a Carter pump, have installed many with no problems. Before you get too excited about carrying the pump back to get another 1, you might want to double check the pressure side fuel line inside the tank to make sure clamps are tight and the hose is not damaged. Could have a pressure leak in the tank.

i accept 1993 dakota sport v6 3.9. when the temp
simply not getting gas. if i wiggle the primal sometimes information technology starts. likewise if i put a heat lamp
near the sensor or injectors it'll first. the
fuel pressure is good. it isn't getting power to the pump. once it starts no problem starting
it after that till the adjacent twenty-four hours. what could my
trouble be. could it exist the fuel pump. some people
say no. hope to hear what you thibk...tks...

These pumps are commonly only sold as assemblies. The force per unit area regualtor should have come with information technology, only it can exist purchased seperately from Dodge for most 55 bucks. Don't simply get a pump and effort to adhere it...the pocket-size nylon line require special clamps and tools, and they can not leak! If you try to accept the thing autonomously and put in a new pump only, y'all probably won't get it together correct. I've seen people effort to utilise hose clamps on these! Be gentle with the sender unit as well, they are easily damaged.

I'thousand looking for "Colts Fan" to meet if he ever resolved his upshot

Thanks guys for responding to my question. I thought about
leaking injectors, simply I had to relieve the pressure off the organisation
before I removed the old pump. Since replacing the pump the
organisation will not hold any pressure when the truck is not running.
I mean immediately subsequently you plough the key off, all of the pressure
is gone to cypher. For it to lose that much pressure that chop-chop, all
of the injectors would have to exist stuck open don't you think?
And if the injectors were leaking wouldn't information technology run rough when you
started it from excess gas in the cylinders? It is hard to start
after information technology sits, but when it fires upwardly it runs very smoothen. Something
tells me that there is something non right with the fuel pump.
Somewhere in the system in that location must be a cheque valve to keep
the fuel from running back into the tank. Could it be in the
pump itself and not closing? But some thoughts.
