Really Hot Relay?


Recommended Posts

Hey guys

So today I've been having issues with driving at 70mph and the trucks completely shuts off, then cuts back on....

First reaction when I get home check grounds...everything is clean and tight...then just so happens I go to the relay strip and one relay was soooo hot as soon as I pulled it I had to drop it because it almost burnt my fingers....

Has this happened to anyone?

 

Edit: it was the fuel pump relay....any Input would help thanks

I just swapped relays and so far no shutting off....

But I haven't done any long distance driving....

This morning just getting to the corner the truck wanted to shut off a few times....

I'm going to do some driving around now and well see how it goes

I would check your wiring to the pump....may be grounding out.

 

Or your pump is on it's way out.

 

Take a minute and check this.....just had a simaler problem with the Daughters XJ......was a broken wire....if yours is shorting or grounding out it would account for the heat.....and the hesitation....  :dunno:

Did you have a complete loss of all electric and power - everything shuts off, then comes back on?

 

If so, the CPS may be going bad. 1st hand experience.

Well this morning it was more bucking than shutting off....

But all lights and radio were still on while it was happening....

Yesterday at 70mph I couldn't tell you if all electronics were on because it was broad daylight and I had my radio off

I was cruising down the hwy and I felt the truck like a sudden loss. I look down at the rpm gauge and it was at 0 rpm. then as soon as I looked around to make sure I don't crash or hurt myself it cuts back on and cruises like if nothing ever happened....this happened twice riding home

Ok so after work before even starting the truck...I rechecked the rear tail light ground to see if it was loose or anything...check

 

Checked the wires at the fuel sending unit...

Cleaned and checked for crimps or splices and everything plays out fine....check

 

What I did notice is that by pulling the fuel pump relay I felt it too easy to pull put of its slot so I bend the constants points a little on all the relays and decided to drive back home....

 

Drove home with ease...but I did do a lot of shifting and moving around....

It's really has happened driving at high speeds or within a few minutes from start up.....

 

Anybody else any other clues?
