Engine turning over but doesn't spark and start

strange starting can be the oil line pressure sensor failing.if this sensor doesn't work correctly it turns the ecu spark off (oil light doesn't turn off when engine is turned over). as long as when you are turning over the engine and the rev counter is moving. if not it can be the crank sensor filed this also turns off the ignition spark. falling all that the coil pack has gone, but to check this you need a meter to check the connections.

Yes you are heading in right right direction. Check to see if there is spark out of coil. Spark at coil means replace distributor or rotor. No spark at coil replace ignition module or crank sensor good luck. Oh yea crank sensor is cheaper i would try that first if there is spark out of coil.

open air cleaner lid and have someone spary a small shot of starting fluid at the same time someone is cranking engine over-if it trys to start you have a fuel problem if it doesn't could be a few other other issues but I would then check to see if you have spark coming from or to spark plugs.

Any gas in the tank...?
Yes. Then
First check fuses. (Injector fuse, fuel pump fuse, head or main engine relay) It's not bad idea to check all fuses.

If all fuses're good (Not blow/burn)
-Next check spark and fuel.

Try bleeding any fuel lines in case you have air in the system.

crank shaft sensor just had this prob its located on top of trans

Check for spark and fuel. When you turn the key on you should hear the fuel pump in the tank for a few seconds till the pressure builds up. When you crank the engine there should be spark at the plugs.

If you are sure you have a spark to at least half of the plugs, and there is no reason to suspect that the engine was being used abnormally just before it was shut down then it is most likely flooded or you ran out of gas.
Black smoke from the tailpipe indicates that the engine is getting a fuel mixture abnormally high in fuel (flooding). White smoke generally indicates not enough fuel.
Unless your engine is damaged or the timing changed, your engine will run if it has the following: proper fuel mixture, air, a spark to at least half of the spark plugs, and compression.
For a "flooded" engine there are two routes. Wait until the excess fuel has had time to dissipate or hold the accelerator to the floor while attempting to start. Be prepared to let off the accelerator about halfway as soon as it starts. And then down to about 1500 rpm. You do not want to over rev the engine. But holding it at about 1500 rpms for about 3-5 seconds will help flush out any excess fuel. You can then slowly return it to idle speed.

Make sure battery has a full charge. If it cranks good but won't start, check the basics. Have a helper crank it while you visually check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse.
If your missing everything, I'd check the cam and crank sensor signals. I realize you replaced the crank sensor.
Any applicable trouble codes? I don't know what testing you have done?
With idle issues clean the throttle body and idle air control, see if it helps? Could be other issues?

The engine needs 3 things to run: fuel, spark and compression. It is most likely either no spark or no fuel. You can check the spark by taking out one of the spark plugs and ground it out on a piece of metal on the engine. Have someone crank the engine and watch the spark plug for a blue spark. It is easier to see if it is in the shade or it is dark. One way to check to see if it is a problem with no fuel is to get a can of starting fluid. Gain access to the intake by taking out the air cleaner. Spray a shot or 2 of the starting fluid in the intake while someone cranks the engine. Don't keep spraying the starting fluid for a long time because it can wash the oil off of the cylinder walls. If the engine is getting spark but no fuel, the starting fluid will cause the engine to run for a few seconds. If it runs for any time at all then you will know that there is spark and the problem is with the fuel system. After you determine if it is a spark or fuel problem you will have to diagnose what part of the system is causing your problem.
