Driving about 20mph with the trailer, the 92 1500 just quit

Postby Davek80514 » Sun Jun 10, 2012 11:30 am



Driving about 20mph outside temp about 98° with the trailer on the back and the 92 1500 just quit. I was a half mile from home and had a little less than a 1/4 tank of fuel. I tried to restart and it won't even fire. I started to push the bike with the trailer back home, and had some people stop and offer to help. I remembered someone mentioning once about a 1500 fuel pump overheating from being old and not being covered with fuel. I asked the people if they could bring me a few gallons of gas which they did. After putting 3 gallons of gas in the 1500 fired up and I got it home. I called my Honda dealer and ordered a fuel pump.
Damn Honda is proud of those fuel pumps! :o

Anyone here had the same problem? or have any other thoughts on this?

Ya know,one thing that pops in my head.
A few guys have had their ECM go bad in that it wouldn't power their fuel pump.
I wonder if a failing pump draws so much current that it overheats and/or damages the pump circuit.

I guess it's a good thing that only the pump quit and not the ECM failed and the pump caused it.

It seems that there is no fuse protection for the pump,so if it starts to drag and current draw goes up it usually destroys the ECM.

I don't know the normal current of a pump,but I'll venture to guess that it goes up a bunch when the pump goes bad due to age and binding.

It's something I'll look into as protection for the ECM.

Perhaps an auto-resetting circuit breaker?

Possible,however, those that I work with operate on a bi-metal switch design.they work well however they also can trip to external heat.I've had this problem with them used under the hood of a police cruiser.when stopped the added engine heat would trip the breaker.
I'm thinking of a current monitor of some sort because a fuse just won't be accurate enough.
Usually a fuse can handle quite a large surge before it blows.
