Ok so my explorers pcm fuse blows every time I try to drive it I can drive 5 feet and it blows I have put many fuses in it the only thing I could do to move it long distance was put a 60 amp fuse in it instead of the regular amperage, I checked for shortages but I did not find any. THIS IS URGENT

How is the mini fuse on location #11? Is that fuse ok? I may need a fax # to fax over some diagrams. The short can be anywhere in the system. Fuse #2 30A maxi fuse controls the pcm relay. Once energized power goes through fuse #11 for oxygen sensors That power also goes through a splice. Splice #123 That splice feeds power to the fuel pump relay, WOT A/C relay, Vapor management valve, and canister shut off valve. Then that splice splices off to another splice #167 which feeds power to the fuel injectors, EGR vacuum solenoid and transmission solenoids. At these point you would need a really good scanner and actuate every single solenoid to see if any of those blows your fuse. Something gets activated once you start moving that blows your fuse. At the moment I would rule out the fuel pump and fuel injectors since it does start without blowing the fuse until you start moving? You may want to look at the EGR solenoid as a possible fault or wide open throttle A/C relay? Drive with the A/C off and see what happens also? But My recommendation would be to try and get a good scanner that can activate all solenoids or just take it in to a shop better equipped for these type of problem. Let me know if you want me to fax over the diagrams? I can fax it over tomorrow morning. Wont be until after 9AM pacific time until I get back in the shop.
