Check your fuel filter and air filter. That is usually where your hesitation starts.

SOURCE: I need the spark plug wiring diagram for a 1994

firing order of a small block chevy engine is 1-8-4-3-6-5-7-2, clockwise-#1 on the front driver side (1,3,5,7 on driver sied, 2,4,6,8 on passenger side)-#1 should be about the 7 o'clock position, but to be certain, rotate the crank (loclkwise) until the 0 degree mark on the balancer lines up with the scale-look at the installed rotor-it is either pointed at the 7 o'clock position or the o'clock position-with the plug in #1 removed, rotate it again to see if the cylinder pushes air (compression)-that is where #1 plug wire belongs. just plug them in in order (18436572)-you will still have to time it to start, they usually need to be set a few degrees before top dead center.

How are the wires supposed to go back on after you put the new starter in for a 1989 Chevy caprice classic 305 v8 8 cylinder E


Big wire from positive battery terminal goes on the larger post in ton the solonoid. The small wire or wires should match up to the smaller ones on the solonoid. Note u could possibly have to shim the starter if it sticks in because it is over shooting the gear a touch.

Spark plug wires


I think I answered this. I believe the numbers are so that you have the correct length for each plug. There is no difference, except for the length. To isolate your problem pull one wire at a time and when the engine smoothness does not change, you've found the bad one. Check the plug. If it is okay, replace that wire with one of your old ones to see if that cures the problem. If that does not help, you might check the cap to see if there are any hairline cracks in it. I hope this is helpful.

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.

Additional details HERE.

Hope helps (remmeber rated this).
