So, just to add to the conversation... I have this issue with my FX50. Replaced both sending units and fuel pump at the dealership. No change. Took my cluster to ezelectronics in NJ to get it repaired, still doesn't work, although I'm quite dissatisfied with their work. Not only is my fuel gauge still not working, now my exterior temperature is blank, and I've lost the ablilty to reset the milage in the center cluster. Button does nothing. I know the button is good, as it works for other functions.

I'm in Jersey, so I'm going to take it back to them to get it repaired correctly. (Luckily they didn't give me the black electrical tape fix like someone else on the forum) I guess they learned you didn't need to drill the cluster.....

Honestly, this car is a giant nightmare. After more than $1500 at the dealer throwing parts at the problem, nothing was fixed. When they told me to replace the IP, I balked, since I didn't want to spend another couple grand when I felt they were just throwing parts at the problem.

I've had 2 FX45's, and a G37 Sedan with no issues whatsoever. This whole ordeal has completely soured me on Infininti.

Just thought I'd vent. I'll let you know if the second IP fix works.

Cheers

Nah it's still a cluster issue. Poked through the ebay listing and you send them the cluster. They're in Austin, Tx, they've been in business 22 years and have 100% feedback with over 1000 transactions so they seem legit. What made me laugh a bit is in the description they state this: "We understand the importance of quality service and the need to get your repaired part to you yesterday or sooner." Then if you look at the estimated delivery date it says this ummkay.

"Estimated between Tue. Jan. 15 and Fri. Jan. 18
This item has an extended handling time and a delivery estimate greater than 15 business days."

Let us know how your experience is with them.

Hey guys. I know this isnít exactly on the topic. Iím hoping someone can shed some light on this situation. I am trying to figure out the fuel level sender situation myself, but only to run a aftermarket dash. (Racepak) does anyone actually know exactly how the signal from both senders is read? Apparently it takes both ohm readings puts them together and determines what level the tank is at. My questions is where is it Taking them two values and converting them? Is it the cluster doing it? Or is it already done and the ohm reading is at pin7 on combination meter plug? Iíve tried getting the reading at pin 7 and Iím. It having the best luck. Does anyone know exactly how this works? This car is a complete sealed car. 2j with a Haltech elite 2500 with a racepak. Factory ecu is no longer with the car. Thanks

Based on the rough schematic in the fsm for the combination meter, it looks like all the sensing is in the combo meter. The schematic shows the two variable resistors in the sending units in series with the resistors in the combo meter that need to be touched up to fix the measurement issue. This would mean to me that the combo meter provides a voltage reference across the whole divider circuit and the voltage is sensed somewhere along that divider to indicate the fuel level. The logical place for this measurement would be in the combo meter. It's certainly not happening in the sending units.

I quickly browsed the haltech website forum and guys are talking about how to do this. They provide some kind of application guidance.
