Chevrolet Repair: 2000 chevy cavalier & 2000 chevy s-10 xtreme, 2000 chevy cavalier, spark plug wires

Question
I thank you for looking at my question's
My 2000 Chevy Cavalier - My car chugs, say if were driving along and doing fine the rpm's will drop and I have no power my car doesn't shut off  it just stops. My whole car will shake. I think it's the fuel injector but I don't know for sure or the cost. Any advice would be much appreciated

2000 chevy s-10 xtreme - It won't start my starter will try to turn it over but it just won't at all. I've never had a problem like this before. There's nothing more I can say everything sounds fine but it just won't start I've tried to the point where my battery was almost dead (my interior lights dimmed and the starter wasn't as strong sounding). Any advice would be much appreciated.

Answer
Hi Dennis, On the cav I would look at the spark plug wires. These are a common thing to go bad on these cars. If you look inside the boots you will see a dark or rusty look inside. The inside should be silver and very clean. Check this out first. On the S10 sounds like a bad fuel pump to me. These also go alot.

        Let me know what you find          Mark
