I have a 2007 Polaris ranger 700 that is throwing 51 52 54 56 codes new fuel pump ,can't find any broken wires need tech help would like to ride

 

 

Look at this "sticky" post above this section on 700/800 efi problems.https://atvconnection.com/forums/pol...ap-wiring.html Injectors rarely fail(not that it can't happen) but most of the time it's wiring or connector issues. Wires may look good to the eye but they can be melted internally. Connectors may look good but pins can pull back and make erratic contact with sensors. You can sometimes wiggle the tbap or tps harness and if you notice an engine change,the problem may be there. Polaris supplied sensor harness repair kits that were junk. Same thin wiring and cheap connectors. From the sticky post came better repair kits from Otb.https://otbpowersports.com/products/ If the manual link I sent doesn't help and you can't trace it down to an individual sensor harness,the best thing to do then is let Digital Wrench try to find any problems. It can save you time and frustration on efi problems.
