Car turns over but won't start?

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.

Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.

2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.

3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

6yrs has past-when was it last major tune-up?

Is the CEL/MIL/SES coming On

Try checking the fuel pressure with and w/o the FPR if it up to spec's-check the CTS/ECT sensor, IACV/TPS

Sounds like you could have a leaking fuel pressure regulator causing your car to flood. You can check to see if the regulator vacuum hose has fuel in it, this is a tell tale that it is bad. Hope this helps

Ok so you have to prime it to start it. I need to know if you have a digital multi meter to do some testing with and can you get a noid light it needed? Also is the check engine light on?

Well Great job Sorry I didn't get back to you quicker but I am still moving to the new house. I am glad you found it and if you have any other questions please just ask me.

Integrated Electronic Ignition (EI) system consists of a crankshaft position sensor, coil pack(s), wiring, and PCM. Coil On Plug (COP) integrated EI system uses a separate coil for each spark plug and each coil is mounted directly onto spark plug. COP integrated EI system eliminates need for spark plug wires but does require input from camshaft position sensor.

Coil On Plug
The Coil On Plug (COP) ignition operates similar to a standard coil pack ignition except each spark plug has one coil per spark plug. See Fig. 8 . COP has 3 different modes of operation:
Engine Cranking

During engine cranking, Powertrain Control Module (PCM) will fire 2 spark plugs simultaneously. One spark plug will fire on the compression stroke and the other spark plug fires on the exhaust stroke. Both spark plugs will fire until camshaft position is identified by a successful camshaft sensor signal.
Engine Running

Once camshaft position is identified and engine is running, only spark plug on compression stroke will be fired.
CMP Failure Mode Effects Management (CMP FMEM)

During CMP FMEM, COP ignition operates similar to engine cranking mode. This allows engine to operate without requiring PCM to know if cylinder is on compression or exhaust stroke.
Fig. 8: View Of Coil On Plug - Typical

A coil in a coil pack is turned on (coil charging) by powertrain control module, and is turned off when 2 spark plugs are fired simultaneously. Spark plugs are paired so that one spark plug fires on the compression stroke and other spark plug fires on exhaust stroke. Next time coil is fired, order is reversed and next pair of spark plugs fire according to engine firing order.

A 3-pin Hall Effect type sensor or a 2-pin variable reluctance Camshaft Position (CMP) sensor is used. CMP sensor is used to determine camshaft position and to identify when piston No. 1 is at Top Dead Center (TDC) of compression stroke. CMP sensor signal is used by Powertrain Control Module (PCM) for synchronizing firing of sequential fuel injectors. Applications with Coil On Plug (COP) ignition also use CMP signal to select the proper ignition coil to fire.

Crankshaft Position Sensor
The Crankshaft Position (CKP) sensor is a magnetic transducer mounted on engine block, next to crankshaft pulse wheel. On all engines except 6.8L, trigger wheel has a total of 35 teeth spaced 10 degrees apart with one empty space for a missing tooth. On 6.8L trigger wheel has a total of 39 teeth spaced 9 degrees apart and one 9 degree empty space for a missing tooth. By monitoring pulse wheel, the CKP sensor indicates crankshaft position and speed information to Powertrain Control Module (PCM). By monitoring missing tooth, CKP sensor is also able to identify piston travel to synchronize ignition system and provide a way of tracking angular position of crankshaft relative to a fixed reference.

Good morning,

I would do a leak down test in all the cylinders as well as a compression test to verify there is no internal damage to the engine. It sounds like you have head gasket damage but needs to be confirmed.

Hello,

This sounds like a crankshaft angle sensor is failing which can happen without triggering a check engine light. Here is a guide to show you what you are in for when doing the job:

This is what it will be like for your car (below).

Here is a guide that covers all of the bases:

Check out the diagrams (below).

Please let us know what happens.

Cheers, Ken

DO YOU HAVE FUEL?

BEING REAL SILENT, WHEN YOU TURN THE KEY TO "ON" DO YOU HEAR THE FUEL PUMP TURN ON FOR A COUPLE OF SECONDS?

DID YOU CHECK YOUR FUEL PRESSURE?

THE MEDIC

Yes is sounds like the crank angle sensor has failed, when this sensor fails it sometimes wont throw a code, here is how you check it https://www.youtube.com/watch?v=RvuzZJqQDf4
