Andrew, simply shorting across the two large starter terminals makes the starter spin but does not pull the solenoid in that engages the starter pinion gear with the fly-wheel ring gear. The large cable that comes from the battery needs to be shorted to the small connector that is usually to the side of the solenoid block, that will then pull the pinion gear forward in to the ring gear then the starter spins, turning the engine. Your original problem could well be just the key.... Do you have a spare key to try ? Even if you do manage to get the engine to spin by the above method the fuel solenoid will also be disabled and the engine just will not fire up. I have come across many key failures in my time as an Auto Electrician. This is the single ellement of the security system that is likely to suffer from abuse (dropping them etc ) The key can be scanned at one of the many retailers with their scanning tool, they may be able to clone the key and make a spare (This is depnding on the make of your vehicle, which you have not stated) Othewise its a dealer you will have to visit and pay dearly for a new set of keys that will also need to be programmed by a tecnician. My advise to anyone who does not have a spare key these days is go and get it cloned before it malfunctions or you loose it.

Testimonial: "Thanks its a 2001 silverado i unhooked the battery cabble lastnight for 30 mins and i got in it and it fired right up and died about 3 times then it finally straightend up and was fine after that i got in it just about and hour ago and it has done it again so i took the cables off again and tried it 30 mins later and it still didnt turn over so i have them off again hoping it will start this time someone told me they know someone that can completely disable the security system and i will never have another problem out of it so i think that is what im going to do because i do not want to get out in the cold and get stranded."

Security maybe ?

Do you have a spare Key ? The key is probably the most likely cause of your problem. Shorting the two main terminals of the starter motor will only make the starter spin, to engage the starter with th fly-wheel you need to short the main lead (usually the outer one) with the solenoid terminal (smaller terminal) However this will not energise th fuel solenoid etc that the security system also disables. You should have your key cloned at your local lock smith retailer before it fails all together. I am an auto-electrician and seen this many a time. good luck.

First place I would check are the battery terminals. Remove them and clean the posts, re-attach and tighten them. You can buy a tool for cleaning the posts at your local auto store.

My Jimmy is having a hard time starting, sometimes it dosen't.

Sounds like your problem might be with the VATS anti theft system. Does your truck have the chip in the key? If so you might just need the ignition lock cylinder changed out. There are 2 very small wires that run from the lock cylinder down the column and plug in under the dash. After time the wires insulation will get brittle and crack. The wires read the resistance of the diode chip that is in the key and send the signal to the VATS computer witch tells the ECM weather to send the signal to the fuel pump or not. On a cold moist morning the resistance signal can be interrupted or the resistance lever raised enough for the computer to get an improper signal. Your vehicle is thinking that an improper key is being used to try and start the vehicle. A replacement lock cylinder can be purchased for around $80 at your local part store and you will need to take your current key and the new cylinder to a lock smith to have the pins in the new cylinder changed to fit your current key. This way all of your current keys will still work the vehicle instead of having to pay $40 for each new key. Anyway, after you have the new cylinder working with you old key simply take it in to have it changed out, shouldn't take any competent mechanic with the right tools more than an hour to change out.
