2003 buick lesaber new coil pack . still no spark what do I trouble shoot next??????


Did you really replace all 3 coils?
Did you have the check engine light on? You should have the code scanned if it was on to tell you what was at fault.

If you didn't have a check engine light indicate that you had a problem, it seems this problem could have been diagnosed without paying for an unnecessary part by going to a certified shop and having an electronic diagnosis.

Other than a coil pack, the vehicle needs a computer to control the spark. That's what the ignition control module (ICM) is.

You did replace all the wires you disconnected, didn't you?

Your ignition spark control module is going bad,your coils pack are located right underneth them. this is what tells your coils packs to produce spark to your spark plugs. they are easy to replace just make sure you mark you coil pack with some tape and make sure you put them back in the same order as they came off the spark control module. Easy to replace,just make sure you use the proper size torx or socket size on the screw heads...

My 1994 park ave, sometimes it starts, sometimes it wont, it does not matter if is is hot or cold, when it is running it runs smooth like there's nothing wrong. I replaced most of the fuel system, spark...


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.
