fuel gauge problems
Question:
With these new computer controlled cars, God only knows why they need so many wires. It used to be just one but now it’s probably on the computer bus and that means a power, ground and 4 signalling wires. The worst part is that you can’t figure out which end is the problem because the connection between them is digital and you will need the good sniffer box in order to see if the transmitter is sending the right message. — Bob May Access1 has gone Chapter 7 so I don’t know how long my website is going to last.

Follow up: I now know what all the wires are coming from the fuel tank. When GM redesigned the Astro/Safari they moved the fuel pump into the tank. From the cluster of wires that leave the tank, does anyone know which ones are for the fuel positioning sensor? What is the resistance of the sensor? I need to know before dropping the tank and the $87.00 for the positioner. I’d hate to put in a positioner to find that the gauge is shot. – Hide quoted text — Show quoted text – > The fuel gauge on my 97 GMC Safari is erratic.

The fuel gauge on my 97 GMC Safari is erratic. When the engine is first started the gauge can go anywhere from full to empty. It usually settles down after a few minutes but has been known to jump for no reason. Any ideas on the problem or how I can eliminate if the problem is in the gauge or tank? The sending unit has several wires running to it (about 6). What area ll these wires? My 94 Safari had only 3 wires running to the tank. Mark
