98 jeep put new crank sensor ' coil pickup' and coil ' i have no power to the fuse block on finder no fire to plugs and dont here fuel pump


No power to fuse block? This may be the problem. Check all your maxi fuses in the power distribution block. I think all the maxi fuses are hot at all times-check if they are getting power, and fuses are good.

Also in the power distribution center is fuse F15- a 30amp fuse for fuel pump relay, and fuse F6- a 15amp fuse, also for the fuel pump wiring. Check that both are good, and have power-F15 is hot at all times. F6 is hot in run or start.
This is the 4.0L inline 6, right? That is the engine diagram I have. The coil signal is from the ECU. Does the check engine light come on with key on, so you know the ECU is powered?

I have a 06 f150 5.4L the fuel sending unit went out so i had to change to pump and everything, the pickup ran fine before but wen i put the new pump in it will not work so i tried resetting the fuel pump...


Hello, There is a fuel pump Relay in the Powerbox under the hood. The system works this way. When you turn on the Ignition switch, it trips the Fuel pump Relay. The power is routed to the fuse from the Relay and then to the Inertia (safety) cutoff switch. Finally the power reaches the Fuel pump.

You need to test the fuse holder for power before it flows through the fuse. You should have the Ignition on, in order for the Fuel pump Relay to provide power to the fuse. Although the fuse may be good, it can not work without power.

On most Models, the horn Relay is the same part as the Relay on the Fuel pump. Just check your part numbers and swap out the two parts and see if it helps.

2000 S10 4.3L Fuel pump stopped working out of the blue. We Put a new Fuel Pump in, new harnes to fuel pump, new fuel filter, new relay, new fuses in IGN C and ECM B fuses. Still the pump will not turn on....


At the fuel pump relay you should have 1 full time hot wire. 1 hot wire when you turn on the switch. 1 ground, and the other wire goes to the pump. Test the ground to be sure it is good. If so then jump a hot to the one that goes to the pump and see if it runs.If it does then you have a bad relay or ECM. You can swap the relay with another of the same # from tour fuse box to test it.There is also a ground on top of the frame near the filler neck, check it too. Good Luck
