On the intake manifold, just left of the distributor, from the front, you will see two raised, threaded holes. There is a bracket that goes around the coil, and bolts to those two hole, with two, 1/2 inch long, 5/16ths, NC, bolts, with a star washer, on each. That is all stock. If you are rodding this vehicle, I can advise you of a trick, I picked up. Get a radiator hose clamp, and drill a hole through it, and then the firewall, near the distributor. Bolt the clamp to the firewall. Then, tighten the clamp around the coil, holding it up, and out of the way, and cooler, than on the intake.
Well on a small block Chevy there will be no coil wire going from the top of the cap to a coil. What you can do to see the difference is go here.
Firewall side of the engine block, couple of bolts hold it to the block, pull straight away from the block when removing as crank sensor, (extending approx. 2-3" long into the block), is mounted directly behind it to the coil/module base
Ignition coil is bad, is it right on top of the cap maybe a bad wire in the wirng harness or bad connector.
The 2005 Chevy Trailblazer has Coil-On-Plug ignition coils so there are 6 "coil packs". Each one is mounted on top of the spark plug.
If the coil looks the same you should be able to use it and only if the coil isn't mounted in the distributor.
Check out your control module under your distribtor cap.
mounted next to the ing coil on the same bracket
Mounted in the center of the distributor cap.
Depending on which coil you're speaking of, it could be marked: ( - ), NEG, or TACH.
The 305 Chevy could not fire for several reasons. The crank sensor could be bad, the coil could have failed or there could be a loss of power to the ignition circuit.
The ignition coil on a 2006 Chevy Cobalt is located on the engine, typically mounted near the top of the engine block. It is integrated into the ignition coil pack, which can be found near the spark plugs. To access it, you may need to remove the engine cover and other components, depending on your specific engine configuration. Always consult your vehicle’s service manual for detailed instructions.
they are normally mounted on the block not to far from distributor check there and see what happens.
