Runs fine just putting around the yard. Get it out on the road and about a half miles it runs out of gas. Let it idle for a few minutes and it will run for another half mile and do it again. Replaced both fuel pumps and filter. Does anyone know if I can get rid of the factory fuel pump?

I have a Coleman 550. Was having problems to start with where it would start and then shut off after a couple tries. It would take off and be good. It then got to a point where it would not start at all. I replaced the fuel injection twice the second time I replaced it I noticed a mouse or something had chewed one of the wires that connect the electrical to the fuel injector. . So two-part question first does anybody have a part number for that wire harness? Second, any other ideas after I fix the wire harness permanently on what could keep it from starting I have gas flow up to the fuel injector.

Have a MSU 500 that we got from my wife's uncle a while back. We've had it running and hauling around the property but it stopped a few months ago after what I thought was running out of gas and I'm just getting to looking into it.
Had fuel to the injector but nothing coming out the injector so swapped with new injector and installed inline filter in the supply hose from fuel pump. Tried again and still nothing but noticed this time that I can't hear the fuel pump priming.
Pulled off the electrical connection and I'm getting 12V to the fuel pump but it won't run. Put it on a test bench and got it to run so put test lamp between +ve and -ve terminals on the connector and nothing. Checked against the passenger seat securing post and get a light.
Tried chasing the wire back and think that the ground is through the ECU but not 100% sure. Can someone confirm for me? And if it is through the ECU, is the ECU just grounded against the frame or is it wired through to the battery?
Thanks in advance and hope this all make sense!

All mid 2008 through 2014 Polaris RZR 800 series have a big problem with the rear differential pinion nut backing off, allowing the pinion gear to shoot into the rear differential, destroying the rear differential. This has happened with machines with as little as less than 100 miles on them! Reports indicate that there are no problems, nor warnings, until the rear differential grenades, locking the rear axles solid! This requires the machine to be lifted onto a trailer, to be transported for rear differential replacement, as it destroys the case. After failure, rear differential replacement can be quite expensive: labor alone can run from $800-$1200 and a new OEM Spicer rear diff, if you can find one, can run from $1700-$2500! So, if you own any Polaris RZR 800 series between the years of 2008-2014, I recommend that you do this repair before further use of your machine. personally, I have grounded my machine until it can be done. Please check the online post for your own awareness.
