Hello,
drive an expedition (F150 platform) with the 4.6 V8 2V Bj 2001 215 hp.

The fuse for the fuel pump constantly flies out. He was still warm on LPG running the car.
Only when the car is cold, of course, is nothing more?

What could be the problem? Gasoline pump or there are weak points with the wiring?
Thank you in advance!
cheers

Dirk

 

Dirk, how about stating the problem again in simple terms!
Is the fuse blowing electrically or popping out of the socket?
Which is it?

I don't know what the rest means or even is important..

 

I think a lot of things are getting lost in the translation from German........

 

Sorry, try to keep it easy.
The fuse (20A on the social under the Hood on driver site ) blowing, wenn I try to drive with gas.

 

If FUSE #10 a 20 amp fuse is blowing in distribution box.
.
It feeds relay contacts on relay#301 in same box.

Then to the Inertia switch located behind top of passenger side Kick panel.

From their to the harness going back to the in tank fuel tank pump motor.
.
Pull relay 301 to see if the fuse holds. If yes the short to ground is beyond the relay. If no, the short is local to the relay feed from the fuse.
Lead color coding assuming it is not different in your equipage.
Fuse to relay 301 .. Dark green and to Inertia switch.
Inertia switch out on harness to the fuel tank … Pink/ Black.
Be sure to check the condition of all leads all the way back to the fuel tank, for wear.

Note; Blowing a 20 amp fuse at Key-On is a solid short to chassis ground.
Good luck.

 

Hi bluegrass,

I change the Relay but the same thing happen.
the relay was a little bit warm.

 

The circuit goes on to the Inertia sensor then to the fuel pump.
Get under the vehicle and look at the wiring from the tank backwards for a ground out.

 

What about the dead-man switch on the passenger side? What must it look like, just press it in case it is activated? What does it look like activated?
