Coil not providing spark

try changing the crankshaft position sensor but first for the fuel turn the key and listen for the fuel pump to kick on if it does and it still wont start find the gas line to the fuel regulator and pull it off and have someone crank it if it has a good pump it will have good pressure and as for the spark if its not getting spark im guessing it has one coil pack together its computerized so it could of gone out but anyway check the fuel stuff first and then change the crankshaft position sensor im almost competly sure that will fix your problem

Normally we start with the basics, are the spark plugs firing and are the fuel injectors opening and providing fuel, and does the engine have compression.
Also, are there any stored trouble codes in the computer?
There is a relay that powers the injectors and fuel pump. You say you are getting fuel so we will assume that relay is ok.
The crank or cam sensor could have failed, or a list of other things.
You will need to figure out if you are lacking fuel or spark to the plugs to proceed.

spark plug wires or coil pack

it sounds like either your not getting spark, or fuel at the engine. it could be the coil packs/plug wires or the fuel pump/filter its hard to say what to do first. when you get in the car and turn the ignition on to the position just before turning the engine over you should be able to hear the fuel pump kick on in an attempt the prime the fuel system. if you can smell fuel at the engine after cranking for a few seconds its probably getting fuel. if you have access to an ohm meter with a wire clamp you can test each of your plug wires as you crank it to see if your getting spark. each coil pack sends spark through two plug wires. if you cant read a signal from two of the plug wires trace them back to the coil packs and if they go to the same coil pack that coil pack has gone bad. if they go to separate coil packs you may have two coil packs malfunctioning. this is where i would start i hope it helps.

A car that cranks over but doesn't start, in many cases will be due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or crank sensor. Also these problems are related to faulty spark plug. Check the spark at spark plugs when you start the car. Do you notice any spark. Actually you should see. If in case there is no spark then it's a spark plug problem. Also the coil pack gives power to spark plug. So check the voltage at coil pack. It will show 12 volt. If there is no voltage noticed at coil pack then its faulty coil pack that has to be replaced. If all the possible options checked out ok then check the car starter. The starter gets power from battery to start the car. If the starter is faulty then it will not let the car to start. Also check and confirm that there is fuel in the car. If its very low fuel then in some cases this causes the problem. Also check and confirm that fuel pump is functioning properly and the fuel filter is not clogged. One of the easiest ways to check for a fuel pump related problem is to spray a little starting fluid into the air intake while trying to start the car. If the car starts momentarily, then there's a good chance the fuel pump is not working or the car is out of gas. You can also listen for the fuel pump's humming sound when the key is first turned on. Also if a inoperative fuel pump is suspected, a good technician will always check to verify there is power and ground being supplied to the pump, to eliminate the possibility of a bad relay or electrical issue. Fuel pressure can be checked with a pressure gauge and if there is pressure, pulse can be checked at the fuel injectors in several ways including the most common, with the use of noid lights. If the injectors don't have pulse the engine won't start. ---------- This troubleshooting tips will help you to solve the problem. Thanks. Helpmech.

You have three choices. First, check the spark and coil system to ensure you are getting a spark. Pull off a plug wire from the coil pack and crank. Have someone watch to see sparks snapping off the coil pack. If you don't have any replace the control module under the coil packs.

Second, you may not be getting enough fuel pressure. Put a gauge on the fuel pressure test port. You may have a bad oil pressure sensor, located down above the oil filter. Check that oil pressure sender and make sure the connector is pushed in. The power to the fuel pump runs through the oil sender. If the engine starts and oil pressure doesn't come up quickly, the computer will shut off the fuel pump. Check this and you can also manually engage the fuel pump from the relay block down by the passenger feet.

Third choice, and it's a long shot, check the harmonic balancer and the crank position sensor. If the sensor is bad, the computer has no idea when to fire the spark plugs. A magnet is on the harmonic balancer and flys by a sensor to induce a voltage in the coil and tell the computer what position the crank is in.

You also may have a bad computer.

You can figure it out.

The spark you are getting is to weak.Check and clean the wires from the coil pack.If they are ok then change the coil pack.Then the crank sensor.Hope that was helpfull.

if youve replaced all that. your getting a spark, BUT are u getting fuel?. could be your in tank fuel pump has gone out. If your not getting fuel or fuel/air into the fuel injector. you wont start.

No, the o2 sensor and coil pack are not the same. The o2, or oxygen sensor, is mounted in the engine exhaust and produces a signal that the cars engine computer uses to calculate how much fuel to give to the engine. The coil pack is an ignition system part, it is what provides the voltage to make the spark plugs fire.
