check your timing chain or timing belt.

Bad fuel pump, fuel filter, it may not have enough pressure or you aren't getting spark

It sure could be. But, first...by "won't turn over" you do mean it cranks at normal speed but won't start?
A simple test of the fuel pump is to stand by tank and listen as someone turns key to on. When first turned to on, your pump will activate for 2 or 3 seconds, pressurizing the fuel system, and then shut off if the engine computer doesn't get a cranking signal. Do you hear it come on? If not, then something's not turning your pump on. If you can hear it buzz on briefly, then maybe it's your filter. Another test: Spray a little starting fluid into your intake manifold (remove the big hose going into intake manifold) while someone tries starting it.If it doesn't fire and try to stay running, then it's probably an ignition problem. But if it does fire off, then you know it's a fuel problem-likely your pump or filter. good luck.

Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they get loud or stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?
Also, do you smell a strong fuel odor when it won't start? May be one or more stuck-open injectors, or the coil pack is bad.
Checking these in the order listed will more than likely fix your problem.
The clicking noise indicates the battery can no longer run the starter, which also means the fuel pump won't run either.
It could be a fuel issue. How old is the fuel filter? Can you hear the pump run for a few seconds when you turn the key on? Try turning the key to ON without trying to start engine three times waiting for the pump to stop running each time. Then try to start the engine. If it starts, Its a form of Vapor lock caused by the extreme heat we have had lately, and a weak fuel pump.

If none of this works, try a new fuel filter first. From there have someone check the fuel pressure regulator and then the pump. If you are in need of a new pump, take my word for it and spend the money to get one from a Dealer, and not from your favorite parts store. Most parts store parts are made in China and they are JUNK.

but is the fuel pump working.if you remove the air snorkel and spray intake cleaner into the intake while someone tries to start the car and it starts then you have a fuel problem.either the pump,plugged fuel filter,fuel injectors not working,dirt in the fuel system.check the fuel pressure if it doesn`t start when spraying cleaner into the intake.

Sounds like a fuel pump..I believe it is located in the gas tank,,,not hard to replace if you have good mechanical skills and some time!

Well then if no pressure at fuel rail then go to pump and in line filter as the in line filter might be the main problem but the pump pressure can also be faulty if filter is bad so check it out and let me know how you get on. Ron

If it is fuel injected it will get enough fuel to start but not stay running. I had the same problem with my S10. Turns out the hose that went on to the end of the fuel pump was roted. pull the sending unit and check the hose connections to the pump and the sending unit. If problem presists replace filter first the pump.

If it has a regular carburator, replace the acceleration pump. It's a small diaphram on the side, near the fuel inlet.
