Hello all,

Here is my dilemma. I installed the Kennedy lift pump about a month ago and and worked fine for a few weeks but then up and stopped working. Did some digging and found the 10A fuel prime fuse to be blown under the hood. The problem is everytime I replace it it just blows the fuse as soon as I turn the key to on and the pump will not run. Anyone experience this problem? Does the pump call for a larger fuse? Is there a factory relay on the fuel pump wire(blue w/orange tracer)?

I double checked all the wiring and the ground connection and it all checked out. I took it to the dealer for a routine timing belt change and had the technician look at it and he was also unable to track down the problem....???

All thoughts much appreciated.

thanks.

I've got a kennedy lift pump and never had an issue with stock fuse. I suggest you check your wiring and look for a shorted wire. Good luck.

The pump itself could be shorted.

This is an expensive Kennedy lift pump, that doesn't fail.

Anything can fail regardless of what it costs

To the original poster. Yes there's a relay in the fuse box by the battery

Disconnect the positive + wire from the pump and install a new fuse. If the fuse don't blow then it's the pump, if it does blow it's the wiring.
