I've developed a circuit board designed specifically to fix saddle tank fuel inaccuracy on older Mitsubishi cars. This video hits home! Mitsubishi ran their sensors in *SERIES* which was insane. They did this purely so they could use the same fuel gauge on all the cars whether AWD or FWD. And of course the senders are not the same; one has a longer range of travel than the other. This is pre OBD, which was common on non-US Mitsubishi cars until the mid 2000s!

Even the oem pump has a wiring correction on the updated replacement. I have a 2010 dodge challenger and that was the case when that pump was failing.

@mikeafa19 ай бұрын
@@PineHollowAutoDiagnosticsI would say that it was @115,000 miles. The pump was still working fine but the fuel level sender was worn away at the electrical sweeper contacts. Or at least very loose, not contacting firmly. In addition to that I have to have the instrument cluster repaired by United Radio in Syracuse NY because that was faulty as well. Some kind of electrical components were burned up or failing?? This didn't report to a BCM module like the 2013 and up models as I see in your video. Lastly, as a preventative measure I also replaced the passenger side fuel module and it was the same issue and amount of wear, so for about $800 bucks and with oem parts I have peace of mind and it has been trouble free for a couple years now.

Those level sender signals just looks like the ECU has a voltage divider. 12 volt feed but the sense pin in the ECU uses a voltage divider circuit which caps the voltage seen at 5 volts even if there is (almost) no resistance from the sender. Somethling like 180 ohms as the fixed resistor in the ECU would do it if the sender also topped out at 180 ohms, but your fixed resistor value is always based off the resistance range of the sender.

Paused at 13:14. Replacement fuel pumps on most Chrysler products come with a replacement plug. This is an update to try to fix a potential plug/socket melting issue. After watching the video all the way through, sure enough. Someone didn't read the manual when replacing the connector. smh. The factory connector has both fuel pump power wires next to each other on one side. The replacement connector separates the fuel pump power wires by moving one wire over one pin. This also changes the order of the fuel level sense wires.

I had an 1989 Pontiac 6000 All Wheel Drive that had this same set up. The tank was saddle style to accommodate the drive shaft going to the rear diff. The driver's side pump was conventional electric and the passenger side was driven off of return fuel pressure that would pump fuel to the drivers saddle. 0-90 ohms each sender was 45 ohms. Never had any problems with the senders or the siphon pump, but i did have to replace the electric pump. Had over 200K, dont really know because the Odometer on 80s GM digital dashboards would only count to 199,999. Pump was a real PITA to replace. Had to remove prop shaft, and exhaust from cat back and it was a northern car to boot.

Shot in the dark here, but I don't understand how that pump is even running also. Could it be that the rewired pump is spinning backwards, cavitating, but the crossover pump is enough to keep the car alive and draw some fuel from the otherside of the tank? The BCM and ICM do dumb down real world fuel levels to avoid the gauge from bouncing around like an 80s GM and do update only periodically while on long trips. KOEO will reset real world levels, and that sometimes can shock a driver who thought they had XYZ fuel in the tank, shut the car off, then upon a restart finds they have less! My 09 Challenger does this and Ma Mopar says it's normal...

Nice info. Love how you’re thinking out loud and showing the step by step process. I got question if you can answer. I installed a fuel pump exactly like this on my wife’s 2010 charger. I had to reorder the wires. They are in the exact order that you’re showing them to be in at 13:38. Is that the correct order? The fuel pump works and the car is running fine and the check engine light is gone now but the needle moves all over the place. I was confused by the order of those two small blue/white wires. On my first attempt, the needle was going back to E and staying there as if it wasn’t reading at all. I swapped the two blue/white wires around and now the needle goes anywhere from half a tank to 3/4 full or full then back to half. Would you wager that the wiring may still be incorrect or could it be something with the cluster?

This is just a knee jerk reaction, but I'm thinking the BCM sends a signal to the fuel gauge that averages voltages from the two sensing units. If the voltage never changes on one sensor (due to mis-wiring or a stuck sensor) it would result in the fuel guage only moving from full to half full.
