According to my Chilton book this is same for either engine. The firing order is 1-5-6-3-4-2-7-8. Standing at the front of the car looking at the engine #1 piston is at 9 o'clock on the distributor and it turns clockwise. The hold down screws for the cap should be at 12 and 6 o'clock nd the window to set dwell should be at 9. The odd number pistons are on the passenger side starting from the rad and the even numbers on the driver's side from the rad. Hope this helps.

I HAVE 1971 OLSMOBILE CUTLAS NEED WIRING DIAGRAM BECAUSE PREVIOUS PERSON WHO WORKED ON CAR TAPPED IN TO THE DISTRIBUTOR WIRE


Kinda hard to post a hand drawing, but basically the wire to the the distributor comes from the coil terminal that has only one wire (unless it also has a noise suppression capacitor. The other side of the coil has two wires, one goes to the ignition switch "on", and the other wire goes to the starter "start" terminal. This is done so that full 12 volts go to the coil when cranking (so that the spark to the plugs is higher voltage and jumps the plug gap better for starting, and because the wire going to the ignition switch has a resistance section that reduces the voltage and we know from ohms law that when the voltage is reduced, the amperage increases, thus causing a fatter spark to assist in fuel mileage and cleaner burn. I bet you can do a search for basic car ignition circuit in 1970.

Why cadillac deville won't start when hot?


Sounds like the module inside the distributor is starting to fail. If the engine turns over at normal speed but won't start then grab a spark checker and put it at the end of a spark plug wire and crank the engine. If if sparks then you have a fuel problem. If no spark then look to the distributor module or possibly the wiring harness inside the distributor. I have seen where the power wire, pink I believe, goes open at the black plastic box connector inside the distributor and can be tested with an ohmmeter. If that is the problem then replace the 2 wiring harnesses that make up the distributor wiring harness because the plastic connector will break apart when trying to remove the terminal and that makes it difficult to put back together. Hope that helps

Problem starting engine


Try cranking it at night in the dark and see if you see spark jumping around the spark plug wires or distributor cap..If you do..Replace them..
Remove distributor cap and check contacts on cap and rotor..
Partially remove coil wire and have someone crank engine and look for spark at wire end.
Pretty sure your car has points in distributor ,be sure they're clean or replace them..
Use Google for locations.

Firing Orders
NOTE: To avoid confusion, remove and tag the spark plug wires one at a
time, for replacement.

If a distributor is not keyed for installation with only one orientation, it
could have been removed and installed improperly and then rewired. The new
wiring arrangement would maintain the correct firing order, but could change the
relative placement of the plug towers in relation to the engine. For this reason
it is imperative that you label all wires before disconnecting any of them.
Also, before removal, compare the current wiring with the accompanying
illustrations. If the current wiring does not match, make notes of the current
plug wire locations and orientation of the distributor cap.

To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.
If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired.

Make sure you give it a good tune up. Make sure that your rotor is moving when you crank it over. If it is moving then you will need to replace the distributor module.
