02 grand caravan 3.3l flex fuel. fuel gauge drops 1/4 tank
Im stumped.I had 02 caravan come in.Crank no start.the fuel gauge read just under 1/2 tank,it almost started when first tried,but sputtered out.I could hear the fuel pump but had no pressure.Went to install new oe pump and found the tank was empty.Put pump in added 5 gal,went for a test drive.As Im going along I notice the fuel level on the gauge is dropping,low fuel lite came on.gauge continued to drop to empty. I find there is a TSB for this exact issue,a resricted vent hose to the LDP filter,I look at all vapor hoses and see no issues.I drive with the gas cap loose,same issue. From Google I see this is not uncommon but I have found no solutions. The one thing I see in data is fuel level in BCM shows approx. 6 volts while the PCM pid shows closer to 3.35 volts. Should these values be closer?
