Question about 2006 Isuzu i-350

1 Answer

Refueling problem I am recently finding that my Isuzu's fuel tank does not fill to the top (short of about 5 liters). I own a 2005 3.5 l V6 "double-cab" pickup. This also indicated on the fuel gauge, which only gets to a mark midway between 3/4 and full. Any ideas?

The fuel sending unit could be bad or siezing up once the float gets near the top. The way they work is the higher the float the or lower the float the resistance changes and the information is sent back to the fuel guage. It could either be the sending unit which is located in the tank or it could be a bad fuel guage. The chances of the issue being the fuel guage is a lot more rare though. Good luck and keep me posted. If you found this solution helpful please rate it when you get a chance.

Thanks - Tech101

    If you have any other questions please let me know. One other idea to verify that the issue is with the guage or sending unit is when you fill the tank up at the pump make sure it is full by checking the amount at the pump. Was there an issue with my last solution? I thought I provided you with a helpful solution and ask that you please reconsider the rating of thanks for trying.

    Thanks again - Tech101

What is wrong with my 2006 V6 Cadillac hesitates to start after refueling

Hesitates after refueling, have someone check the FPR, Fuel Pump and Filter.
If you have junk in the tank, it will circulate when you add fuel to the system.

Hope this helps

I have a 2003 Hyundai Santa Fe, lately everytime i fill up it takes a long while to get it started again.Once it's started, it's fine until the next fill up. any suggestions??

Sounds like the purge control valve on your evaporative system is stuck open. In this case, what happens during fill-up is that fuel vapors are forced from the fuel tank into the intake manifold, effectively flooding the engine.
Todays fuel tanks are vented back into the engine. A "Carbon Canister" is supposed to absorb the vapors and then feed them into the engine in a controlled manner. If your canister is saturated or the purge valve stuck open, the fumes can "flood" the engine while refueling. Try holding the throttle wide open when you start after refueling to clear the vapor quickly.

Also next time you go to fill up, don't fill it all the way, maybe half or so, since the evap lines are at the top of the tank this should solve your problem, and give you at least some good information to take to your mechanic

Fuel comes back out when refueling

EITHER your filling to fast or the breather pipe on the side of filler pipe
which lets the air and fumes out as you fill the tank .
Or the fuel in the tank is very hot which will also cause the same problem as you only use less than 1/3 of fuel the pump pumps up and the other is returned to the tank and after a run its warm fuel in there.

Refueling problem with my Isuzu

Does the pump at the gas station just stop when you try and fill it up? There is a charcoal canister up towards the front engine compartment that the vent line runs to from the gas tank. You can check it and make sure it is not clogged but nothing can really cause a gas tank from not filling it up all of the way. I think you have a defective sending unit. You would have to take it to a certified mechanic to take a look at the gas tank if you feel it isnt filling up all of the way. They may have a special tool to check it. Hope this helps. Good luck. - Tech101
