9 Answers


It does not have one per se - It has a Fuel Pump relay controled by the ECM "B" fuse and the ECM/PCM itself. The relay is in the underhood relay box. 30 will be hot all the time 85 is your key. It will become hot for 3 seconds when the key is initially put on. It will stay alive when the key is in the run or on positionb if the ECM/PCM is working correctly. If everything there is okay then its a ground problem at G102 or G402 or Wiring issue to the pump Good Luck

EECMB fuse blowing I found wires running from fuse box to rear of truck thay look like thay where going to fuel. I replaced fuel pump only thing is the fuel pump touches the bottom of the fuel.. well I put it in anyway. Si primed pump truck starting right up ran for about 10 min and stopped ecmb fuse. Replaced checked wires under drivers sear and injector wires drove it for a mile and it stopped running. So know I'm running 10gage wires to ground on fire that goes to ECM ground from and ground to manifold . My big question is the fuel pump touching fuel tank bottom who is that house ecmb fuse to blow my next step is to check fuel pump relay . I did ground everything to to negative on battery to insure a good ground . Am u going in the right durection
