Okay I have a question my firing order is lined up my spark plugs everything is aligned and wired right it firing orders right it still will not fire off what else could it be

Check primary current to coil. Must have voltage going to coil with key in on. Then test coil with a multi meter set on the ohms (resistance) setting. If coil is within specs, check or test the Ignition Control Module (ICM) . If the ICM tests good (any parts store can test for free), suspect the Crank Position Sensor, or Cam position sensor. This is a start for testing the ignition system.

I changed the HT cables on my 2y engine. But got it mixed up. Need helppliz

firing order is 1-3-4-2 , but for this to help you will have to know where the HT cables connect from ,as you haven't mentioned year i don't know if youv'e got a distributor or coil pack/s , you may already know the position for the HT cable at the coil end, so the firing order is all you need , any more info req'd just post

What controls the fire to the coil

The ignition system is controlled by the Powertrain Control Module (PCM) on all engines.
Here is a generic breakdown of most ignition systems incorporated after 1996;

The system uses separate ignition coils for each cylinder. The one-piece coil bolts directly to the cylinder head. Rubber boots seal the secondary terminal ends of the coils to the top of all 6 spark plugs. A separate electrical connector is used for each coil.
Because of coil design, spark plug cables (secondary cables) and a distributor are not used.
Two knock sensors (one for each cylinder bank) are used to help control spark knock.
The Auto Shutdown (ASD) relay provides battery voltage to each ignition coil.
The ignition system consists of:
  • Spark Plugs
  • Separate Ignition Coils
  • Knock Sensors
  • Powertrain Control Module (PCM)
  • Also to be considered part of the ignition system are certain inputs from the Crankshaft Position, Camshaft Position, Throttle Position, 2 knock and MAP Sensors

Firing order on a 305 on the cap. Got the wires all messed up...

This method is good for the firing order on all chevy small block v8 engines from 265 cubic inches to 400 cubic inches. This would include 265, 283, 305, 327, 350, 400 cu. in. chevy small block v8 engines.

Let's cover some safety concerns first. If you try to troubleshoot a mixed up firing order with the engine running, you could be in for a serious shock,.. literally. You can do it, with certain precautions, but you really don't need to check the firing order with the engine running. You definitely don't want to try checking the firing order if you are wearing any kind of pacemaker or sensitive electromechanical prosthesis. The voltage coming out of the ignition coil is in the thousands. Common sense dictates that you wouldn't stick a knife in an electrical outlet, so you wouldn't want to take chances with being shocked by the electrical discharge from your classic chevy's ignition coil either. See the diagram:


5d6424a.png

The firing order, which should be cast into the intake manifold, for the chevy small block V8 is 1-8-4-3-6-5-7-2. The firing order is the numerical sequence in which the spark plugs are fired. The insertion position of each spark plug wire around the circumference of the distributor cap can be found according to a clock face. The insertion sequence determines the firing order. The firing order is followed clockwise around the distributor cap starting from the 6:30 position with the 6:30 position being the number one cylinder spark plug wire.

On classic chevy small block engines that use ignition breaker points instead of electronic ignitions, the number one cylinder is the one immediately clockwise of the small metal sash cover on the distributor cap. The firing order starts here. There is no sash cover on the distributor cap for GM HEI electronic ignitions, and the firing order is the same, but starting at the 5:30 position.
The firing order makes sense if you know how the cylinders are numbered. The number one cylinder is the front most on the drivers side and 2 being the front most on the passenger side. From front to back, the cylinders are odd numbered on the drivers side, and even numbered on the passenger side.
