30 amp EEC and fuel pump fuse keeps popping

Good evening,

I attached a wiring diagram for you to view.

I would disconnect the inertia switch and see if the fuse still fails.

If it does, it could be the fuel pump. If it does not then it could be the ECM or wiring at the ECM.

The inertia switch is located on the LH side of trunk, below air suspension electronic control module.

Roy

Okay, thank you. if that doesn't work are there any other wiring diagrams you can send me for the ECM? do you think it could be a short somewhere?

One step at a time to try to narrow the area of failure.

Start with the inertia switch and let me know so we can proceed.

Roy

Okay, thank you. i will lyk today after i try that.

You are welcome.

Keep me updated.

Always glad to help.

Roy

It ran for like 30 seconds then the fuse popped when i revved it up i unplugged the inertia switch with the key out it blew the fuse right away there is a computer mounted above the radiator fan that vibrated and made a noise for a second any suggestions where to look next.

Okay, then it is not the fuel pump.

Unplug the fan controller and see if the fuse still fails.

That is the piece on top of the radiator shroud.

Roy

1. Disconnect battery ground cable, then remove radiator sight shield.
2. Disconnect electrical connector, then remove integrated relay control assembly from radiator support.
3. Disconnect electrical fan connector, then separate connector located at top of fan shroud.
4. Remove male terminal connector clip from shroud mounting tab, then remove air bag crash sensor.
5. Remove fan shroud from radiator.
6. Lift cooling fan module to disengage from lower radiator clip and end tab.
7. Slide cooling fan module clear of radiator hose connector, then remove two engine wire harness clips from side of fan shroud. Lift module past radiator.
8. Reverse procedure to install. Torque shroud to radiator nuts and bolts to 36 inch lbs.

Unplugged the fan controller tried to start it would not start but did not blow the fuse. plugged it back in started it and it blew the fuse instantly. could there be an issue with the wiring or is the fan controller the issue?

The fuel pump relay is part of the module. That is why it would not start.

It is a very common failure.

Replace the module.

Roy

Okay, thanks again. i will try that.

Would you recommend a used or new one? and what is the technical name of the module?

New only. You can get it at Rock Auto.

Roy

Okay, what is the technical name?

Cooling fan control module.

Can you give me the part number of the old one? I will see if I can find you one.

Roy

This is the procedure:

Roy

1. Disconnect battery ground cable, then remove radiator sight shield.
2. Disconnect electrical connector, then remove integrated relay control assembly from radiator support.
3. Disconnect electrical fan connector, then separate connector located at top of fan shroud.
4. Remove male terminal connector clip from shroud mounting tab, then remove air bag crash sensor.
5. Remove fan shroud from radiator.
6. Lift cooling fan module to disengage from lower radiator clip and end tab.
7. Slide cooling fan module clear of radiator hose connector, then remove two engine wire harness clips from side of fan shroud. Lift module past radiator.
8. Reverse procedure to install. Torque shroud to radiator nuts and bolts to 36 inch lbs.

Description

The EEC Module receives signals from the Engine Coolant Temperature Sensor, Vehicle Speed Sensor, and Clutch Cycling Pressure Switch to determine if the Electric Cooling Fan should be activated. When conditions are met to activate the Electric Cooling Fan, the EEC Module will provide a signal to energize the EDF Relay (2.3L and 3.0L) or HEDF Relay (3.0L only) and operate the Cooling Fan.

F1d7 aa is the part number i think.

No, there are a lot more numbers.

Roy

Okay, I will look and see.

Okay, keep me updated.

Roy

This is it is this the module you were referring too.

Could you check and see if the one on O'reilys.com is the right one and let me know please?

If you were sending a picture, nothing came through.

Please try again.

Could you let me know if the one on O'reilys.com is the right one ?

I found a remanufactured one for you. You should call them and see if they have it.

There are lots of used ones but I never trust used electronic parts at all.
