New Fuel Pump Issues *gauge not working* I recently dropped my axle , and put in a new tank and fuel pump. (from rock auto) After putting it all back together and putting $10 of gas in , i noticed the gauge didn't move. Concerned, i drove to the gas station and got another $30 gas. The needle went up but barely at all. What could be the problem? Do i have to return the fuel pump? |
Re: New Fuel Pump Issues *gauge not working* Maybe the float got caught up on the tank wall or something. I just replaced pump also on my 88 2.8 but I went with the trap door method. Gauge still works fine. Naaa its not the fuel pump that's the problem it's the sending unit or float. This is exactly why the trap door method is the best, If there's a problem you can get in there quick and fix it. But when you drop the tank you have to make sure everything is good to go before you put everything back together. Now........ I know you don't wanna drop the tank again.:lmao: |

Re: New Fuel Pump Issues *gauge not working* Before you pull anything again unplug the connector between the body and the fuel tank. Take a resistance reading from the negative wire and the sending unit wire. Should be between 0 and 90 ohms. Your measuring the fuel tank side BTW. See if that reading matches the fuel gauge. 0 is empty, 90 is full and infinite is an open |

Re: New Fuel Pump Issues *gauge not working* bad sending unit wire grounding |

I put in about $30Canadian in and then another $10 today and it went up. Just a bit though . When tank was empty gauge said below empty. When there was $30 in it said empty. And another $10 made it go up a hair. So it’s reading. If I fill it up and it says say example “half tank” and I know it’s full.. what do u think the problem would be |
