- June 25, 2015, 08:15:43 AMCouple of things to start with...does the efi light come on with key up? If it does the fuse is ok. Next. the fuse is located in a separate holder, white in color, near the battery, on the back frame cross member. Third thing...The ECU grounds the fuel pump to make it run. There is a 4 wire connector for the pump. One side is B+ with the key on, the other runs to ground through the ECU.The connector should be under the speedo console. Do you have an aftermarket ign. switch? The first gen. OEM switches have been known to fail just like this, too. The Thunder kit for relocating requires a special wiring mod to allow the pump to run. This fails and leaves you scratching your head...same with the older OEM switch, been there, done that. Here's a diagram of the plug. Get out your 12v test light and check stuff.

- June 25, 2015, 01:03:47 AMWhere is the ECU fuse at? Does anyone have a part number? I am troubleshooting the fuel pump. The tank was full of rust cleaned it up along with fuel pump and bought a new battery. I cannot hear the fuel pump working and I'm thinking maybe it's something electrical. I've heard about the ECU Fuse and the ignition switch being out. Starting with the cheapest first. 1999 drifter 1500
