I left it out in the cold a few days ago, I was storing it in the gagrage but the other day decided to leave it outside overnight. Now it will not start. Any help, maybe something simple? It has been only in the middle teens for high temps here in Chicago. I have a feeling no one will reply anyway so ohhhh well!! I am quite sure it will fire up sooner or later.

ok, does it even try to start?
Did it get wet outside?
If it got wet, you may have gotten water in the distributor cap. Could be bad leads or plugs too.
See how you go, give us more details if you can, this may help in working out what it is.

Well thanks for replying, it ran fine the day I left it at the shop. I had broken a garage door spring so I left it outside, the only moisture it encountered was the half inch of snow that fell that night. But the thing is it when I turn the key it just clicks like the battery is weak but it is not. It is fully charged, it sounds like the starter hit a dead spot so I tapped it a hammer and nothing. I was just wondering if these things are hard starters when it is really cold out. Oh and this is kinda got me mad too, I looked under the thing and there is a small puddle of Hydro fluid, I think. I know it is not motor oil. The few days it sat in the garage, there were no leaks under it at all. So now I have a leak somewhere too.

I would first try to narrow the problem down. First, I'd measure the voltage at the starter with the key on, but not in the "start" position. Should be 12v or so. Then I'd have an assistant move the switch to the "start" position. The voltage should drop some, but still be up around 11 volts if the starter is not turning, maybe 9v or so if the starter is turning. Assuming the starter is not turning as you described, and you still have 11 or more volts at the battery terminal on the starter, then I'd measure the voltage at the smaller terminal on the solenoid. That should also be around 11 v when the key is in the start position. That voltage is supplied via the key to actuate the solenoid. If no voltage, then there's a problem between the key and that solenoid. If it's 11 or more volts, then let's check just after the solenoid, probably a very short large wire, from the solenoid but quickly disappearing into the starter housing. When there's voltage on the solenoid, there should be 11 or more volts on this short fat wire, and the starter should whirrrrrr. If voltage, but no whir, then I agree with you there's a dead point on the starter. Whack it some more, I started my truck that way when it's starter went out. If the voltage is not present on this short fat wire, the solenoid probably isn't working correctly. Whack it with the key in the "start" position, maybe it will make contact. And, if it's working properly, you should be able to hear the solenoid produce a healthy clack when the key is to "start". There's a start on your troubleshooting (pun intended). --- Bob

See if you can isolate where the CLICK is coming from, is it the starting relay from the key or the olenoid on top of the starter. It isn't un-common for the copper contacts inside the starter solenoid to play up, if you hear a click from the starter and no movement it could be a bad winding or more commonly it will be a bad contact inside the relay on the starter its self.
Personally, i would just use a screw driver and bridge the 2 large connections on the starter solenoid. 1 comes from the battery, then you have one small usually copper braided wire that goes inside the starter its self. If it jumps to life you know its not the motor, but it is either the starting relay or the solenoid.
As for the hydraulic leak, i hope its nothing major or worse still, somewhere you just can't get to!.

Something Else you may want to look at is make sure you didn't hit the auxillary lever and kicked in into detent, if your engine does crank it will not very long because the pressure in pump will build up. It is just another common problem I see out there on these the 742 and 743's that the dealerships soak you for.
