My 94 Chevy Lumina APV will not start and only makes a clicking sound when turning the key. I replaced the battery and starter but the problem is still the same. I bypassed the ignition switch with a remote starter and still only got the clicking sound. Is it electrical? Any suggestions?

My neighbor asked me to look at his '98 Kia Sportage 2.0L 4cl. Said it just stopped dead. I looked in the oil spout on the valve cover and noticed that the cam was not turning when cranking the motor. Uh_Oh, bad timing chain. It has about 100,000 miles on it and has been well maintained. Does this engine use a timing chain or belt ? And does the valve train clear the pistons on this motor ? How much should my neighbor expect to pay $ for this job at a garage ? I said between $ 500 and $1,000 Do you agree ? I don't have any hands on experience with a Kia. Thanks for your replies.
