Quoted From dreamer2355:
Does the vehicle run fine once started? Usually, if you have an issue with a plugged fuel filter, it would hesitate under WOT.
You may also have an issue with the FPR and im under the assumption you have a return-less fuel system, hence the FPR is apart of the fuel pump assembly.
You should see a drop in fuel pressure if you hook up a fuel pressure regulator if that check valve was bad.
You don’t always get a hesitation with a plugged fuel filter. I have seen them hide pretty darn good but cause and extended crank or multi prime.
Just because the service number is right does not mean the software is right.
The service number is like a class identification for certain bodies.
If you are in over your head you need to take it to a shop to be at least diagnosed for the problem, then you can focus in on the correction path.
If you are trying save some money on a repair by doing it yourself you need at least a basic understanding and some basic but special tools to get through it.
Not everyone can do the DIY thing no matter how many videos Eric makes. The knowledge and experience doesn’t get transfer by just watching a video.The service number is like a cross fit ability reference for software drivers, kind of like trying to run a printer on your home computer without running the disk.
The computer sees the component but hasn’t a clue what it is or how to use it.
The ECM is no different so long as the internal software supports whatever hardware your car has. In your case your vehicle may have three 02 sensors where the one it came off had 4.
Don’t concentrate on if the wiring is there or not, doesn’t matter. The only thing that matters is if the pin is there to utilize a driver for that component.
Not all pins are used and not all wires are used.As easy as it sounds it is not. You must have a vision from an engineers standpoint to understand where the underlying problem is and is why the DIY crap goes to the way side sooner than later.
It could be as simple as a severely clogged fuel filter.
There are a few things you can do without touching the fuel filter to confirm if you have a DSO.
You can simply see how many amps the fuel pump is drawing to start and then look for a lean condition at a wide open throttle through a 1 – 2 shift while monitoring the LTFT to confirm.
The LTFT should remain in the high digit positive and both up streams should stay +800 mv.
The fuel pump amp draw should be respective 6-9 amps or so. 10 amps and higher would raise concern and I would suspect the fuel filter.Or you could just crawl under it, remove it, and then try to blow through it to confirm.
I prefer hooking up a good DSO and scan tool to make a diagnostic decision then make some other grunt change it. Makes em real happy and wonder how the hell I did that without ever racking the vehicle or screwing a pressure gauge on itW;)
It is most likely to be in the auxiliary heater system running to the rear of the van. Look to the bottom side in the middle area and trace them with your eye and you will see they are rusted and possibly find the leak without pressure testing.

my friends car screeches, even when she drives it please please please help me out
Step 1. Lift the radiator cap
step 2. Replace the car under it.Problem solved!
Seriously? Dude! You got to give more info than that or refer to my first two steps.
I will usually not advise anything outside the scopes of manufacturer testing. The reason for this is because the maker of the vehicle is the one who knows best and is absolute.
What that actually means is in the event that an issue would have to go to the American courtrooms the Judge will only take consideration within the engineered testing provided by the manufacturers and that information is perfected even if it is the wrong path or the long way to to a conclusion.
You need to do some checking to see if it is getting fuel and spark, then focus in the direction of which one is absent.
These carburated models don’t take much to run so it should be simple to diagnose.
FYI that Scannerdanner guy has a great book for any advance performance wannabe guys out there. Think it is like forty bucks or something but it is only available online and not paperback.
If you have an ear to hear, this guy is your instructor…
