Several months before my fuel pump developed a crack, my gas gauge light began the 8 flash blink code once the the gauge hit about 1/2 tank - which is the point it switches from the main tank sending unit and begins estimating remaining fuel based on mileage. I lived with it that way and was looking forward to having normal gauge/light operation restored once I replaced the fuel pump. Unfortunately, replacing the fuel pump has not cleared the 8 flash blink code at 1/2 a tank. So I thought it must be a wiring issue - probably a lose connector. So when I replaced my air filter and added the intake shim and needed to disconnect and reconnect all wiring near the the tank/console/filter - I thought surely my gas gauge/light will work once again. Not so either!!! So now I am even more puzzled as to what the issue could be. I don't think I have disconnected the battery since the problem showed up (although I have never had that actually fix anything for me on any vehicle in my life). Actually, if I remember correctly, the gas light issue started several weeks or maybe a month or so after replacing the battery. But I will try disconnecting it tonight just in case. Has anyone actually had the light problem disappear after disconnecting the battery? By the way, I did have the console gauges disconnected while I installed the air kit/filter. While the ECU didn't have power removed, from what I can read from the schematic in the manual, the fuel sending unit goes directly to the gauge console and not to the ECU at all. Not sure if the console does the interpretation of fuel level and the calculations, or it if works with the ECU to do so (in which case, possibly an ECU reset could help).
