Simon-





More than likely it a poor connection between your battery cables, the starter and ground.





At this time of year, batteries tend to start failing due to the heat and lack of maintenance.





Lets do this together shall we?





Lets start with you disconnecting the battery cables and cleaning them. If you do not have one, purchase a battery terminal brush from your local parts store and a product by Permatex called Battery Terminal Sealant. Its sold in an aerosol can, and as its name imples, that's what it does.





If you have not cleaned the terminals properly you are probably going to find some white fuzzy material on the terminals.





Now I will also warn you. GM's better idea to use the infamous side terminal battery had caused no end of corrosion problems for them.





So be prepaired, you may end up having to get some additional parts to get this fixed, but I will get into that in a moment. For now I will assume that you are able to get the terminals loose.





Once you have them off, you can take wire brush or the battery terminal brush and clean the terminals, then re-install them, then coat them with the terminal sealant.





This should solve your issue.





Now we come to the additional information. Should you encounter battery terminals that have effectively welded themselves in place because of the corrosion, you are going to be into a pretty involved repair. For the record, it normally not the Negative Terminal that gives you the trouble. Its normally the Positive Terminal that is the @#$%ing issue.





Normally in this case you totally wipe out the head of the connector bolt, so be prepared to purchase all of the following items.





Battery


Positive Battery Cable


Di-Electric Silicone Grease


Permatex Battery Terminal Sealant


Terminal Wrench


Battery Terminal Bolt





Normally of the Positive Terminal Bolt is stuck or corroded in place, the battery has cracked around the terminal and allowed electrolyte to corrode, (Cold Weld), the terminal bolt in place. So The battery is pretty much a history lesson at this point. It will also cost you the cable, because with it being welded in place you have two choices. Cut the cable, or cut the bolt head off. The bad news is, the cable normally does not survive you cutting the head off the bolt. So the way we handled it at Chevrolet, (Cut the cable and don't waste your time).





After replacing the cable, check the ground cable for corrosion, at the base next to the frame. If necessary, clean the area, then seal it with a glob of the Di-Electric Grease.





This Grease is a special electrical conductive grease, that insulates against water, but allows an electrical circuit to be completed without adding resistance to the circuit.





Install your new battery being sure that you have completely cleaned the area. After you have installed the battery, clean the terminals and apply a small amount of the Di-Electric Grease to the terminals of the battery AND the threads of the battery terminal bolts. Install the cables and bolts, then tighten them properly. You may need the terminal wrench at this point to be sure that you don't strip the heads.





After you have completed this, use the battery terminal sealant and coat the area between the base of the cable and the battery terminals, along with the tops of the terminal bolts.





You should be go to go at this point.





Now how did I know about this?





Just gave you some free CCT, (Chevrolet Certified Technician Product Training).





Yep, been turning wrenches for GM for a while. I work in a parts house now, and am more than happy to help customers with that extra little bit of knowledge.





Good Luck, and I hope that helps you out!

this happened to my old 89 camaro. my brother put the starter in with the wires all messed up..maybe the wires came loose or theres a bad connection there. not to mention the alternator was bad.
