Re: Replaced cam and crank sensor and coil pack found cam...
Disconnect the negative battery terminal to see if the system will reset.If it still will not fire,the module in the computer may be burned out,replace the e c m,the computer.

If you have any dtc's, follow the flow chart. If no dtc's present, I would check your intake for any clogging. Can't tell you much without more information
Primary voltage to several systems, including the ignition coil, dark green wire with orange tracer. That voltage comes from asd relay. There is a fuse for asd relay. To check for voltage the engine has to cranking. The control side of asd relay, the computer has to ground it before it will energize. Did you check wiring circuits for cam and crank sensor connectors before replacing sensors? Are there any applicable trouble codes?
Are you ok with testing wiring circuits?
ECM requires both crank sensor signal and cam sensor signal to fire the coils. Check for spark at the plugs first. Check the plug wires, then the coils. Only if you have no spark at any coil would I suspect the ignition module, and even then only if you have a good crank and cam signal. Do you have any codes stored in the ECM? They could help pinpoint the problem.
If its not getting spark the choices are limited. You already replaced the coil pack so whats left is ignition module, crank sensor, knock sensor, cam sensor, or the timing was not was not set properly when putting it back together. Any one of those would create a no spark situation.
Make sure you cleared off the Error Code after you repaired it. An Error code will stay for 25-35 Startups before it cycles out of the system.
Check your power wire to the coil and see if is at least 12 Volts. Other possible problems for the coil would be getting reliable firing sequences from the Crank and Cam sensors.
If you have replace new cam sensor with no sparks and the coil are good putting out 12 volt, my guess would be the computer it self faulty. cam sensor sense the cam turning and send info to computer telling computer to disperse the charge from the coil pack to the plugs assuming relay, cam sensor, coil, plugs, and wires are good. make sure the cam sensor is put in properly and position.
cam sensor fires the injectors to synchronise injector pulsing with the spark at the spark plugs.. U need to probably change the crankshaft sensor (around the crank pulley) as the crank sensor is what controls the ignition spark.
hope that does it.
