Question:

Do Co2 detectors and smoke detector wear out and need replacement?

Ive had the same CO2 detector for more that 10 years. Do they wear out? I have been told that I should replace it with newer technology of detector.

Answer:

Yes. Just make sure to save your receipt.
Cathi gives you the correct answer. Christal is wrong.
The first thing I would check would be the timing belt. When was the last time you had it replaced, if ever? On my 1989 Ranger, I can see the camshaft pulley by looking behind the plastic cover that covers the timing belt. If the camshaft pulley turns when the engine cranks, it's probably not a stripped timing belt. The other answerer gave a good suggestion to check the fuel safety cutoff switch that is located under the glove compartment. Next, I would check the fuses for the fuel system. You will probably find those under the hood. Try removing the fuel pump relay fuse and putting it back in . If the fuel pump relay is going out, this may shock it back into action. The fuel pump is a possibility, but Ranger fuel pumps are usually very reliable. If it isn't something simple, I would suspect something electronic, perhaps even the computer. As I discovered on my Ranger, the computer controls everything. And when I say everything, I mean everything. I do a lot of the maintenance and repairs on my truck myself, but when my computer went out a few years ago I had to take it to a shop to have it diagnosed and repaired. Fords are known for computer failures. Unfortunately, computer and electronic repairs are beyond the abilities of most of us shade tree mechanics. Hopefully, this is something simple, but if it's not, you may need to have it towed to a shop for diagnosis and repair. I've had my 1989 Ranger for over 20 years. I bought it brand new in 1989 and it is still my primary vehicle. Rangers are very reliable, especially the 2.3 four cylinders, and with proper maintenance your Ranger still has a lot of life left in it.
If you buy the special flame resistant safety clothing available from them it's deductible but not the regular cotton or denim. As an employee it will have to be deducted as non reimbursed business expense on schedule A. subject to the 2% rule, which means in practice it's not deductible. If you're an independent contractor it's all deductible.
