Water in fuel? Starts and then dies.

Although my water in fuel light didn't come on in this video it has been coming on when doing this same thing. I had this happen about a month ago, put some sea foam in the tank and it worked itself out, so not sure if there was actually some moisture in the fuel. This time I have drained the fuel bowl and put sea foam in it, and it's still doing it. Could my water in fuel sensor be bad or I have heard there is a fuse to it as well. What else could it be? Only thing different is I have been adding 2 stroke oil to my fuel instead of optilube. Going camping Thursday and need to have it remedied ASAP.

Re: Water in fuel? Starts and then dies.

Well I unhooked the water in fuel sensor and fuel heater that plug into the back of the fuel bowl and ran it for a few minutes then hooked it back up and seems to be running fine. We will see how it goes. Would still like any advice if you have any.

Re: Water in fuel? Starts and then dies.

I would not be putting seafoam theough my injectors... they're just too damn expensive, and seafoam isn't gonna do anything good for them. Secondly, your problem is doubtful to be from water in the fuel. I'd scan for codes. There's such a number of things that can cause the truck to die like that. You can do a few checks though, like unplug the icp sensor, see if there's oil in the connector. If there is, you need to replace the sensor. Check the stamped tin nut on the back of the ipr to see if its tight. Check the harness going to the ipr too. But like I said, you will probably need to put a scanner on it.

Re: Water in fuel? Starts and then dies.

And I see you have a chip also. If everything I mentioned checks out, unplug the batteries, keys out of ignition, and check the chip to see if it has worked itself loose.

Re: Water in fuel? Starts and then dies.

I did the sea foam in the tank, not the bowl if that's how it seemed, as it pulls moisture out of the fuel. Not something I really like doing either. I will look into your other suggestions as well. Thanks for the replies.

Re: Water in fuel? Starts and then dies.

Where/ how would it "pull moisture" out of fuel? Its snake oil. The seafoam doesn't just magically evaporate, nor does the water, and it doesn't matter if you poured it in the bowl or the tank, its still running through your injectors. But again, I HIGHLY doubt water in fuel is your issue, and you need a scanner on the truck.

Re: Water in fuel? Starts and then dies.

From seafoam. I'm not pushing it, but it's helped me in two scenarios so I'm not complaining.
Moisture: Fuel can absorb moisture from the atmosphere and from condensation – even more so with the addition of ethanol. Sea Foam fully emulsifies the water in the fuel. Allowing the moisture to burn through the engine and be harmless.
I'm no expert and not claiming to be. Do you use fuel additives or are those all snake oil as well? Just curious as to your thoughts on them.
I have the torque app so will run a scan and see tomorrow.

Re: Water in fuel? Starts and then dies.

I'm not saying every product out there is a "snake oil" but a lot of them are. Every so often ill add some ashless two stroke oil to the fuel, and a bottle of power service, but not too often. Let me know what codes you find

Re: Water in fuel? Starts and then dies.

Adding an emulsifier to the fuel will prevent the water separator in the fuel filter from doing it's job.

If the video posted is your truck...(or it's acting identically as yours)...I would look directly at the IPR wiring and/or ICP sensor.

a truck with lots of water/gas or no fuel pressure won't run smooth like the video...it'll run with ridiculously high ICP pressure and make a very very sharp, crackly (engine) sound.
