I have an 05 Expy and this is the proper way to wire in an external relay.įirst. There are videos to do this, but a lot of them suggest wiring it in improperly so that the fuel pump runs whenever the ignition switch is on. If the PCM relay is good, and you only fried the fuel pump relay, I recommend just putting an external relay on and wiring it in. The circuit board was not designed properly to take the heat from those undersized relays. But remember that all you are doing is resetting back to the same potential problem being able to happen again. So I know there is a bunch of people that like to replace the CJB (Fuse Panel). The reason for the difference in part numbers is the addition of the power cable in the package along with the fuse box. The part number on the package is 3L1Z-14A068-AA.īut the part number on the fuse box itself is 3L1T-14A067-AA New 20A Panasonic JMM131 micro relays replace the 15A Osrams. But it could be internal to the fuel pump relay and not visible unless I cut that little POS open. I'll pull the old fuse box apart and examine the board and micro relays and see if I can find the problem. (Disconnecting the battery, and reconnecting it allowed it to start.) The reason for the replacement was a crank / no start condition after short drives. So hopefully this one will last as long as the Expy does. The latest one was manufactured in November 2020 and has 20 amp Panasonic micro relays instead of the 15 amp Osram relays.
It was manufactured in November of 2013 but still had the old 15 amp Osram fuel pump relay and other micro relays just like the original '03 fuse box did. The second fuse box was installed in January 2014 due to the typical melted fuel pump relay and PCM relay.
