You need to start by turning the crankshaft pulley to TDC (top Dead Centre) There should be an alignment mark on there for reference. Once you have this, then remove the distributor cap and refer to the position of the rotor arm. It is pointing to number 1 plug lead (number 1 cylinder). You can start from that reference and hook up No.1 plug lead. Then, as your rotor arm turns clockwise, it should hit the following cylinders in this sequence: 1,8,4,3,6,5,7,2.


1,3,5,7 refers to the left bank and 2,4,6,8 refers to the right bank.

SOURCE: We've replaced the distributor cap and rotor in

This is a one piece distributor. It has the coil and pickup sensor all built in. Check and see if you have 12 volts on the large red wire that plugs into the cap while the key is on. (The other wire is for a tachometer if you have one). If you have power and there is no spark from your ignition wires, your pickup module is bad in the distributer. Very rarely have I seen a failed coil.

I need to know firing order for 1982 chevy van 305 v-8? was told order is 1,8,4,3,6,5,7,2 clockwise order but not sure where to begin order


put a socket on the nut for the crankshaft dampener and rotate the crank until you get to top dead center of #1 cylinder-remove the cap, the rotor is pointed to where #1 is located. you can have someone bump the starter with the key (disconnect the power feed wire to the distributor if you do this)

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).
