I did a tune up and when diconnecting the wires from distributor i noticed that they were different from the manuals order (153624) i did not note down how there were. Then when i put the new wires on in the manuals order(153624) it will not fire up

1969 Chevy 396 Firing Order







Different for an in-line straight 6 with a 250 engine: Firing order is 153624, # 1 is front cylinder, distributor rotates clockwise timing: 4BTDC auto trany TDC standard trany point gap is .019 point dwell is 31-34 according to an info provided elsewhere.

153624 is the firing order , take our No. one spark plug, turn engine over till compression is felt, turn engine till mark on crank pulley lines up with mark on timing cover, this is No. one on compression stroke, the distributor rotor must now be pointing to No. one on the cap, note the way the rotor moves , clock wise or anti clock wise following the movement fit the plug wire to No. 1 on the cap and No one cylinder ,next No, 2 on the cap to No,5 cylinder and so on.

Starting at the front of the engine, the plugs are 123456. The order on the distributor is 153624 clockwise. Number one on the distributor is the tower that points towards the right front headlamp, usually the second tower clockwise from the front screw that holds the cap to the distributor.

For a 6 cylinder, it is 153624. the distributor turns clockwise. For 8 cylinder is 18436572 the distributor also turns clockwise.

300 straight six 153624 distributor rotation clockwise, 232 v6 142536 distributor rotation counterclockwise.

255/302/360/390/460 15426378 distributor rotation counterclockwise,

351 & 400 W & M 13726548 distributor rotation counterclockwise.

Order is 153624 #1 should be the tower on the distributor that points to the r/f headlight. Direction is clockwise.

I don't have any info back that far but here is a way you can sort it out. With the valve cover off, watch the valves on #1 piston, should be the front one, as you turn the motor over. As the piston comes around towardsTDC the intake will open and close and as you go past TDC the exhaust will open. Just back the engine up toward TDC which will be when your timing marks are lined up and where your rotor button is pointing at that time is your #1 wire. As you turn the motor over to line up #1 take note of which way the distributor turns and you can wire from #1 once you find it.
The crank turns twice to once of the camshaft so if the valves don't open in the proper order the first time keep turning. They should next time. Hope this helps.

153624 is the firing order ,or do you mean the low tension wires if so reply to this and i will have a look at my one in the garage tomorrow
