Cold Start Problem

Hi Everyone,

We're new to this forum and looking for some help.

We have a 2008 Joyner Renegade R4 800cc. For about a month, we have had trouble starting it when its cold. When the engine is warm, it starts fine. Once we got is started on Saturday, we were out all day and had no problems until Sunday morning when we could not get it started it at all. It's in the shop now and they cannot figure out what is the problem.

There was a lot of sand/dirt in the intake manifold which was cleaned. There is no diagnostic hookup on the machine even though the manual says there is one.

The only other thing that may be worth mentioning is that it overheated a couple of months ago when water hit the fuse box and shorted out the fuse for the fan.

Any help we can get would be very much appreciated.

Welcome to the forum, sounds familiar for both Renegades and Troopers, I have the Trooper and have the same problem. Not cured yet, but I'm working on it. If you come with a fix, Please post it.

Again, Welcome to the Forum, a lot of good, helpful people here that are interested in helping and being friendly.

Hi yowaysc and welcome to UTV Boards. I love the Renegades and good to see a few more owners popping up here.

I have had a problem with starting a Renegade before when cold and it was fuel pressure. Turn your key enough to run the fan and fuel pump once and see what the fuel pressure is. Then do the same another 3 or 4 times without starting and check again. You can wait to see if it drops but I would just go ahead and start it and if this is the problem it will fire up. This problem resolved itself after I took off and reconnect all fuel lines.

I have had two 08 R2s that had the fuel lines plumbed wrong so next time check the routing from the tank onto the Carbon can control valve and fuel filter through to the fuel regulator. Mine would not start and nor should yours if it is plumbed wrong but you never know so still check and while you are there make sure all connections are tight.

I would also check your voltage on your battery. This was the cause of my Trooper not starting. The battery seemed fine, just a little weak but as soon as I replaced with a new battery, away she went. The stock batteries on the 08 models are very average.

Lastly, it could be a failing fuel pump. Hopefully the shop will sort it out for you.

Now, if I'm not mistaking, on the first run of Renegades up to half way through 08, the diagnostic connector wasn't routed back to where it's supposed to be near the ecu (as shown in the Renegades owners manual). Anylizer (a UTV Board member) posted all the good oil on this somewhere so will try and find it for you, but there is most certainly a diagnostic connector.

Cheers Mike.

Found it................... Joyner Forum

after many hours chasing wires, I found the diagnostic connector routed clear up by the fuse/relay box under R/H front fender. Joyner said it should be near the ECU "not". On the mid production 08 models it is, but on the first run of machine they forgot to re-route it to the back. This is a 3 wire connector that doesn't have any thing hooked to it. It is only usefull if you have the scanner. This info is mostly aimed at dealers who might be having trouble finding the diag. port. I also had to remove 2 of the 3 wires from the connector to get data to flow. The center and one of the 2 end ones. I had to trace wire color from ECU to determine which wire was diag. lead. On this particular machine it is the yellow wire, disconect the other two. Good luck A.

      You will quickly see that I am new to this and don't quite know how to pose this question. I gave myself a Coleman 400 UTV for my 65th  birthday a month ago."To Yaya: From Yaya" I've noticed a couple issues. First, as I drive around our acreage, sometimes it just putters, almost sounds like it's going to turn off. The other issue is the lights on the dashboard that correspond with forward, neutral and reverse don't match up to the actual gear. Sometimes it does but most of the time it doesn't. What I mean is that when I put it in forward to drive, the reverse light will be on the dashboard light. Sometimes it will be the forward light. When I put it in Neutral, sometimes the light on the dashboard /N lights up and sometimes it doesn't. Lastly the gas gauge does not register. Although the tank is almost full, it shows E / Empty.

      This is a new problem for my 3400. When plowing, it shifts into reverse with no problem. When I try to shift to high or low is when it’s hard, sometimes VERY hard to get it in gear. What’s up?

      Massimo Buck 250 less than a year old.  900 miles on it.  Live on beach in TX...i.e. corrosive salt air and normally mild temps.
      The story - one day, it randomly quit on idle and was tough to restart.  Next day, it occasionally cut out for 1-2 seconds while driving, then catch back to normal throttle.  Pumped gas pedal, not sure if that helped it catch.  Added some marine sta-bil and filled tank.  Ran well after that for a day.  Following day, wouldn't start.  Turns over, cranks, but won't start.  When it quit on idle that was the first time driven since we did have a freeze of ~25 degrees.
      Full charge on battery. No spark.  Changed plug and still no spark.  Fuses look good, but fuse connection box has some loose clasps and spade were corroded. I bent clasps best I could and used dielectric on spades re-inserted.  Cleaned and checked every connection I could find.  Don't have a card reader to hook up, but did swapped ECU just to check that, and no change...after swapping ECU the engine light now stays on.  Previously blinked and then goes away.
      Under warranty but service place is 2 hrs away. 
      thanks!
