Hi all,thanks in advance for any info. I have a 06 ranger 700xp . First off I'll say that I have read most of the threads about replacement parts and such and this site is really helpful. I'm pretty mechanically savy and I do most repairs and services myself. Since I've owned this ranger I've used a lot of info on here to work out most of the little bugs and such and get my ranger running pretty good. I had a suspicion that I had a tps going bad (previous owner spliced into it deleting the connector) Long story short I bit the bullet and took it to the dealer just for a diagnostic welfare check . They are telling me that all is well ,but during inspection the mechanic checked my fuel pressure and thinks my pump is starting to fail ,I asked how so because it's something that I've checked and it was healthy. He said that it is healthy when it's running but as soon as you shut it off it drops out and it is suppose to hold pressure ,so he thinks the regulator is starting to fail.Hmmmm... Sounds fishy but I have dealt with these guys a lot for parts and they are all good guys so I don't want to assume the worst here but for $800 and some change for the whole assembly to be installed I just can't justify it.( not made of money) I've checked out all the replacement parts as far as the fuel pump goes ,but I don't see a lot about the regulator. Kinda stuck here not sure what to do at this point. Thanks again!
