I've been having a few problems with my Cadillac Series 62 recently. I can't start my vehicle. I know that it's already old, but I hope I can still do something for it to work. It has been with me for a few years now, and it has been giving me a fantastic ride every time. Not until this morning when it suddenly seems to be retiring. What could be causing the problem?

There are several reasons behind an engine that won't start. For one, it could be due to corrosion issues. You should clean your battery terminals and cable ends first, and then try starting the engine again. If you found any corroded cables, replace them with a new one. You may bring your vehicle to the repair shop to get it done. If there is no problem with your battery and cables, then you might have an open circuit either in the solenoid switch or the starter itself. You may check your solenoid by shorting it using a jumper wire with clips. If the starter spins, then your starter is okay. Otherwise, you need to replace your starter.

I don't usually drive my Cadillac Series 62 since I bought a new truck. I left it sitting in my garage for over two weeks. Yesterday, I tried starting it. I heard a loud noise, sounding like a clicking valve lifter. I immediately turned off the engine to keep it from getting damaged. I let it cool down overnight and tried again this morning. The sound is still there. Will I be able to use my car again? What should I do?

Whenever you leave your car sitting for a while, it is inevitable that some of its parts will settle and cool down for good. A noise or sound coming from your vehicle is an indicator that something is wrong or out of place. The sound that you heard could be your valve lifter, which is not pumping up like it used to. It could be that or an oil pressure issue. You may want to check the oil pressure using a gauge. If not, then you should bring your vehicle to the repair shop to have it checked. There might be parts that are already worn out that totally quit and failed. You need to have these parts repaired or replaced as necessary. Take time to start your vehicle once every day to keep the parts from being stagnant.

This morning, I heard a single click coming from under the dash when I started my car. I can't find where it is exactly coming from. I'm just using a screwdriver to jump the starter and get it going. I want to find out, once and for all, what's causing the problem? What should I do?

Your ignition switch could be failing, but before you buy a replacement part, you need to confirm this by diagnosing it using a multimeter. This is to check if it has indeed stopped working and needs replacement.
