First Question - How much room do you have?  Next question - How much money do you have to spend?  I have a large garage with a 9000 Lb. 4 post Lyft.  I work on cars, light trucks so I use this to pick up my Mule Pro.  Works fantastic as I am 6'-4". 

I test my injector signal before I start replacing injectors.  Harbor Freight sells a NOID Light Kit for $33.00 here in Central Florida.  Easy to use and much better idea than throughing parts with money better spent elsewhere.  My $0.02.

I am a retired Diesel Mec.  First thing I did when I got my 2016 mule home was to take apart every connection I could find and added Dielectric Grease.  I took every ground I could find, cleaned the metal surface, coated with dielectric grease.  I have taken the mule through 3 ft of water with no issues.  Recommendation is check all powers and grounds.  Alot of issues come from bad grounds.  Also, check the power connection to the fuse block for corrosion and tightness.  Check the connection to the ignition switch for corrosion and the connections for tightness.  This is always my starting point with these UTV/ATV's.

2016 Mule Pro FX.  I moved my battery from the stock location up under the seat.  I measured the Battery Dimensions, using 1 inch wide flat bar, fabricated a basket, welded it to the frame. easy to do.  Hardest part was running new cables from the engine to the new battery location.

I am a retired Diesel Mec. I drive a 2016 Kawasaki Mule Pro.  I bought a Demo from the Dealer.  First thing I did when I got the machine home was to take apart every connection I could find and added Dielectric Grease.  I took every ground connection apart, cleaned the metal surface with a BRASS wire brush, coated with dielectric grease.  I use the machine for Farm work as well as hunting.  Been through 3 ft of water with no issues.  That said, if you are having electrical issues, check your powers and grounds first.  Then you can trace down any issue's 

Yes, it was a combination of a bad ECU and Fuse Box Corrosion.  Once the owner gets it started, runs fine.  Now the issue is the battery is not charging.  Replace the Rectifier, got 14 vdc on the battery.  Now am only seeing 13 vdc.  When I have time , gonna have to verify the alternator output.  Then I am gonna have to make a new fuse box, can't buy one as you have to buy a complete wiring harness which is like $400.00  which the owner doesn't have.

Did you ever get this sorted out?

Awaiting for  new ECU to show up Tuesday the 16th.  Contacted the local dealer, they said sure bring us the bike, pay $100.00 to Troubleshoot.  if it's the ECU. pay $550.00 for a new part plus 1.5 Labor hours @ $95.00/hour.  Said, nope, I will just replace it myself.

Have a 2013 KRF750S Teryx  that starts and runs 10-12 seconds and then shuts down.  Also ,  notice the Multifunction Meter panel acts like it looses power. Turn the key off then back on, the Multifunction Meter panel starts up, then immediately shuts down.  The machine needs to set for at least an hour before trying to start then shuts down again.  [i.e. the symptoms repeat]  I believe the ECU is failing but don't want to make a $500.00 mistake  The service manual only addresses failing sensors, not the ECU.   Any ideas on how to test if the ECU is failing?  If it was a car/truck, my computer scanner will tell me.

If not already mentioned/done.  Pull every connection you can see, flush with fresh water, dry off(I used a hair dryer) and fill with dielectric grease, then reconnect.  I did this one at a time.   Also, while you have the plugs out, spray WD-40 or your favorite lubricant into each cylinder.  This will lubricate the Cylinder n Rings and prevent corrosion from starting.  And don't forget to drain the front and back differential.  Is possible you got water in thru the vent lines if the water was deep enough.  A friend also had to pull the starter to clean it out.  Sat in the muddy water to long.
