If no spark - test the ICM.... Ignition control module.

TESTING Remove the ignition coil(s).

1. Using an ohmmeter, check the resistance between the primary terminals on the underside of the coil. The resistance should be 0.50-0.90 ohms.
2. Check the resistance between the secondary terminals. It should be 5000-10,000 ohms.
3. If the coil failed either test, replace the coil.

I can't remember which way they turn, but, you need to get a tool that spins the piston while it spreads. I want to say they spin counter clockwise but I can't remember. You're local auto parts store should have a tool you can rent and they will probably know whick way they spin as they spread.

are you having charging issues are you thinking the diode in your alternator is bad??????????

do you hear the fuel pump turn on when you turn the key to the run position? If not the check the fuel pump relay.

If the car will start and run for a few seconds then die, It may well be the crank position sensor.

may need to replace coil pack.

Hi. Check for blown fuse inside the fuse box expecially for the brake light fuse. if fuse are ok, check the bulbs. If bulbs are working fine then this could be a wiring problem.

should be a diagram under the hood of the car.

Hope helps (remember rated this).

more than likely you have leaking injectors. thats where i would start

Look at your fuel filter or fuel pump or a bad fitting on your gas line. If the code p0756 shows up. It will be your SHIFT SOLENOID B CKT PREFORMANCE or STUCK (OFF). But more than likely look at your fuel pump.

You might try a crank sensor, most of the time if you pull it out you may see a crack in it. It's between the top of the oil pan an the transmission, good luck.

most likley a fuel pump issue. The only way to know for sure is hook up a pressure gauge and when you have symptoms check the pressure. If you spray some brake cleaner or quick start when it doesnt start and it does start then this is an indication of a failed fuel pump or fuel pump relay. If it still does not start when you spray then you have an ignition issue like a crank sensor or ignition module.

The drive axle nut will need to come off and the torx bits to the wheel hub will need to be removed

impeller is what your looking for I think
