Sure the new coil is working? Did you check for spark?Is the fuel pump working? Fuel injectors? ECM?

Why car my car start?


No spark? Then there is probably no signal to trigger the spark. Possible causes:
1) Cam position sensor.
2) Crank position sensor (you replaced it)
3) Coils (already replaced)
3) Wiring and connections to and from coils (bad grounding points or bad live feeds)

Suggestion: Stop the guessing and spending with "probable" causes. Have the car scannned for error codes and start from scratch according to error codes.

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.

NO SPARK OUT OF THE COIL


Spark is created by the ignition module and crank shaft sensor remove distributor cap and use a logic probe red led shows positive voltage green shows negative voltage. the crank sensor has two wires with key on touch the leads and find the power side then have someone crank it over logic probe should flash a yellow color or toggle green red (2 bulb model) that shows a good sensor replace module. stays red then replace sensor.

Car will crank there is no spark have replaced coil and condenser


Test the ignition system output, ignition systems can vary in configuration but operate on the same principal. Ignition systems can consist of a coil, pick up coil, crank angle sensor, cam angle sensor, spark plugs, spark plug wires, distributor cap, ignition rotor and a distributor and any variations of these components. An ignition coil is a voltage stepper coil that transforms a low voltage (12 volts) signal into tens of thousands of volts needed to jump the gap of the spark plug.

This coil is activated by an ignition module triggered by using the camshaft/crankshaft angle sensor; timing is adjusted by the PCM (computer).This primary electrical signal is generated by the PCM which calculates spark timing by using a variety of sensors including coolant temperature, mass air flow, and oxygen sensors. Go to 2carpros.com for a video on how to check this using a 12v light tool. On the engine repair section search, type, "engine cranks but will not start." If my answer helpe you, please leve good feedback. thanks

Replaced coils and car started. Then it just stops and wont start again


Check for spark, if no spark, check to see if you have rpm signal. if no signal that look at the crank sensor. crank sensor will give you a no spark, so will an ignition control module, the crank sensor is by the crank pulley, the control module is under your coils.

Wont start


is the your car engine cranking when you try to start, first check spark plugs ignition coils, remove one ignition coil and spark plug fix the spark plug in to the ignition coil then connect ignition coil to wiring and keep spark plug body touching on ground of engine head mettle parts, ask some one to crank engine then you can see is the plug sparking or not, do the same way to all the coils and plug otherwise you have to buy a ignition spark tester, is the all the coils and spark plugs are OK then check the fuel pump, it's sitting in under rear seat, before that do one thing disconnect oxygen (O2) sensor wiring and crank engine, the thing is if your oxygen sensor completely dead fuel pump will stop working, if engine start after disconnect O2 sensor, replace new O2 sensor, otherwise need to check fuel pump relay fuse and fuel pump. is this information helped you? please vote me and give a comment.
