Cold Start Problem

[yowaysc]

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.

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.
