Ok I know this is a old thread but I am having the same problem with my 02 AV. My Ecmb fuse keeps blowing and I cannot figure out what is wrong. I think I checked all the wires none of them are corroded, I replaced the fuel pump relay, and checked the 2 grounds coming off the battery and 2 that are on the frame rail going to the fuel tank. If anyone knows what might be causing this PLEASE let me know I've been reading that this is happening to other AV's but no one has put the solution to the problem? I don't know what else to look at it reads no codes and I can't afford to take it to the dealer right now cause they want it for 2 full days at $90.00/Hr just to diagnose it which is just crazy! At first it was happening at every 1/4 of a gas tank, then at 1/2 tank I don't know if this is just a coincidence or not, and it happens within 5 minutes of driving. I REALLY appreciate any help, Thanks in advance!!!!
