Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if okay-check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,cap and rotor,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems

with compression and valves opening and closing at the wrong time/broken or jumped timing

belt/chain.

You need spark, fuel, compression, and correct timing. What have you checked so far, and what were the results? It would take an hour to type all the possible things that can cause a no-start condition.

Does the battery die over night? Have you checked for electrical draws?

If the battery is fully charged, does it die right away?

IF it dies that fast, can you find anything overheating?

You need to check things. Anything that can kill a car battery that fast, has to be drawing a ton of power which would create heat. Go to our homepage under the DIY section and find the directions for checking for an electrical draw. See if there is one. If there is, remove one fuse at a time until the draw stops. Let me know what you find.

Have it scanned for both hard and soft codes.

That means that most likely the ECM is fried.

ECM=PCM=ECU
