    I think my primer pump died I did an oil change and she didn't want to start I noticed I didn't hear the pump after checking the fuse I also checked the connector the wire and connector were hot and the pump was really hot...
    How difficult is it to change that pump? And is there s wireing harness for it?

    Very easy to fix, four bolts and it drops down, I had the same thing happen, mine turned out to be short in the wiring harness.

    A guy can do it with a mobile truck, so I'm gonna say not too overwhelmingly difficult.
