Check to see if you are getting spark to the plugs. Also, if you are getting spark, check the fuel pump pressure.

Okay, if the engine turns fast, there is a loss of compression. Either bent valves or the timing is wrong. Please keep in mind, the belt may have jumped a few teeth and still look good, but be off. You need to check that again and tell me what you find.

And gave me another keybut before the key got lost the car was working perfectly, though have parked it for over a year now.

If the engine is off, you can't bend a valve. I didn't know that. If the engine is turning fast, however, there can't be enough compression to start the engine. You are getting gas and spark because you said the plugs were wet and you had spark. I need you to check engine compression. If you need directions, go to our homepage under the diy section.

Let me know what the compression is in all cylinders. If you can and want, video tape it so I can hear what is going on. I could tell you right away if the compression is to low. Also, while sitting, you may have had a couple valves stick open.

Sir, if you get spark and fuel, have good compression, and the timing is correct, the engine has to run. It has no choice. You told me it turns fast, faster than it did before? If so, the compression is low.

A stuck valve can cause low compression. If you check engine compression, I can point you in the right direcion. If I am wrong, then we need to check the timing. Since the car sat for so long, there is a chance that a few valves have stuck in the open position.

For directions on checking compression, visit our homepage under the DIY section. It isn't hard to do. You will need a compression gauge. Most parts stores will lend or rent them to you.

Let me know what you find. Also, if you can send a video and upload it for me to listen to, it may help.

IF YOUR VALVE GUIDES ARE DRY---WHEN YOU TURNED THE ENGINE OVER INITIALLY, THEY MAY HAVE STUCK IN THE "OPEN" POSITION----SPRING'S CAN'T MAKE THEM RETURN TO CLOSED----JUST A THOUGHT

DO COMPRESSION TEST

Did he find low or no compression? If so, remove the valve cover and locate the valves that are sticking. Cover them with oil and gently tap on them to see if they release. They should.

When my mechanic opened the top cylinder he noticed 10 valves got bent so he removed the 2 cylinder and he said he will grand the cylinder and later fix it back that the car will work then, and he. Said the timing jumped aswell. Hope notin will happen to the cylinder if he grand it? And he said he will change the jasket too that if he uses the old one that the car might do over heating. That's all he said. What's your best advice or his he doing the right tin?

I agree that the gaskets need replaced. Additionally, since the timing has jumped, I recommend replacing the timing belt. That is what caused the problem in the first place.

If he is able to replace the valves and everything else in the head is in good condition, you should be fine.

At least we know why the engine was turning over so fast, no compression.

Thank you so much for being there all through. I will tell him all what you said. In nigeria we believe a four cylinder engine is better than a six cylinder engine. Is it true? And how can one manage a six cylinder engine. Can you also tell me the advantage and disadvantages of the both?

Honestly, one is as good as the other. As long as maintenance is done on them, they will both last you a long time.

A 6 cylinder, by nature, should have more power, but isn't any better or worse. Other than when it comes to fuel usage. A 6 will be likely to use more.

Let me know if you have other questions.
