I have some time this week to do some more T/S on the wheeler. I rang wires to the ECM from the sensors according to the repair manual. All wires were good. I then began ringing the sensors themselves. All were good until I got to the IAT. The manual states it should be around 2.45 ohms with tolerances between new and used. Mine reads 2945 ohms....might I be on to something? That is an extremely high resistance according to the tech data. Anyways, I put the new tires on so if I need to I can at least get it to the dealer now.

At this point sounds like the best thing to do rather than throw more parts at it.Digital Wrench can for the most part can find what's wrong and narrow down any problem areas.

I guess I messed up the last post. Anyways, I recently purchased a house and am able to work on the wheeler. Put a pressure tester on it and was only getting 2 psi after buying a new pump and pressure regulator. I thought I possibly got a lemon pump and ordered another. Upon closer examination I found a crack that goes completely through my pressure regulator housing. For now I will attempt to weld it. Does anyone know of a source that I can get a new one without ordering a complete tank assembly?

Ok. I plastic welded the pressure regulator. Put a new pump and pressure regulator in.When I turn the key on it shoots up to 401 psi. When I turn key off it drops to 25psi. While I am cranking it stays at 40-42 psi until I release the key. It acts like it wants to start on occasion but also backfires through the carb. I tried starting fluid but no luck.
I will check codes later but does anyone have any ideas??
I getting frustrated now!!!

Would you want try this regulator? Its not cracked. Its not the same as yours but they do the same thing. It is off a polaris, just dont remeber which year and model. If nothing else, it could rule out the crack, even though you welded it. Pm me your address and ill send it to you if you want to try it. If your in the us and not alaska or hawaii. I cant imagine it would cost me much to ship to the lower 48.
