Hey, I have this Silverado and had recently changed all the plugs, wires, the distributor cap and rotor, the fuel filter, pump (about a year or so ago) ... and now I cannot seem to get this thing to crank. The computer always read that it was having a multiple cylinder misfire, but never could find it.

About a week ago, I got ready to go out in my truck and it wouldn't crank. It would turn over a few times, but it would shake horribly and die. Then, it got to where it won't turn over, it just turns really slowly and then makes a clicking. All my lights and electrical equipment still work inside, but I'm unsure of what it is. I added Heet to my gas, I checked the levels of everything, I don't see any corrosion on my battery terminals (its a side terminal), but I am grossly ignorant under the hood of my truck. Anyone have any ideas?

Patrick; The clicking noise is classic 'low battery voltage'. Could be poor connections at the battery, or the battery has finally given up the ghost. Disconnect the cables (negative first) and inspect/clean as needed. Remove the bolts that connect the cables to the battery and clean in there, too. Then, charge the battery if needed. A fully charged 12V battery will have 13.2V, but doesn't mean it's good. A load test will answer that question. Once this is taken care of, then you'll need to address the P0300 to find out what is causing it.

DON'T JUMP!!!!

It's ok to post just once here too.

Ok: GM side post terminals are a trouble spot so don't just glance - take them off and really clean them up and know that the battery is good - separatly charged and checked if need be.

Those side posts are famous for just what you are experiencing. Baking soda, wire brushed clean then when dry some grease will preserve them. If no good whole quality cables or high quality end splices can work well. Note - I said high quality - not just the dollar cheap temporary ones!

Cables also need to be good at starter and engine block too.

Happy New Year,

T
