It's a new coil, Norm. It's chrome. I wanted to add a little bling so I bought a chrome ignition coil. I'd post a video of it running but I still have to rebuild the power steering pump, and I didn't put any coolant in it. I should do that- coolant, check the oil and transmission fluid, make sure they're topped off, check everything for leaks. I have to connect the carburetor linkages, and adjust the "kick down", I might still have to tighten up the exhaust. I have the "coverage" this weekend- I'm on call. That's why I'm not at Grandma's today, but it also means I have the whole day off tomorrow.

Not a good time to chime in, but your starter needs new brushes too. Glad you figured it out and got the car running.

Congrats Davek!!!!

Similar thing happened to me and my Jeep…I tried everything and then found out the dizzy was tooth out of location… fixed and Jeep fired right up.

Major props to GS72 for mentioned re-checking fire order and wires!

Jesus loves Oldsmobiles too!

I put a dab of grease on the ends of the shaft and re-assembled it. It's already back in the car. I'm going to crank her over just to see if she spins any better... then I'll check the points, rotor, condenser... I'd love to run a compression test on the cylinders too, esp if the starter works better. Maybe I'll get more than 20 minutes before the battery is dead again...
Those brushes should have been replaced.
A couple of them are so worn out that the insulated brush holder is contacting the armature.
This is what new brushes look like.

Okay, no big deal, turn it the other way and- wait a minute! If that's advanced more, not retarded... then the rotor spins.... the other way. I had the firing order reversed, as gs72 suggested- thanks Gary! It sounds like a big block...
For future 59-64 394 reference.



Lot of people get thrown off by the 1-8-7-3-6-5-4-2 firing order on these too, especially if they're used to the later GM 1-8-4-3-6-5-7-2 firing order.

You really need to find Volume 4!😄

You've heard about the " 4 and 7 swap " performance cams on the market?
Well , they didn't invent that idea.
Olds did that in 1949.
Why they went with the more "conventional " 18436572 order ( a la Chevy & Cadillac ) in 1965 with the new second gen engine is a mystery to me.

Hey Joe- if the battery drops when you crank it, it might be a problem with your starter. First, chase the +wire along the driver's side to a junction post, where you'll find a few connectors to pick up 12V. Make sure it's clean. I put the starter wire directly under the battery terminal so there's nothing in between to draw down the voltage. As a test, you might pull everything off except the battery and the starter leads. Check for corrosion, check your ground. Make sure the ground is clean, no paint or grime between the wire terminal and the block.

I'm still thinking it's a bad starter, but check everything else first.

One more thing that'll be helpful- get a "momentary switch". It's a push button switch that closes a circuit only when you hold it down. You can get one at any hardware store. Get 2 alligator clips- a small one for a small post, and a larger one for your battery terminal. Get a length of wire, maybe 12 or 14 gauge, and wire up the switch between the clips. Now you can clip one end to the low voltage terminal on your solenoid, and the other end to the + battery, and you can crank the starter from under the hood, instead of from the driver's seat. It's a useful tool for troubleshooting starting problems.

Good luck.

Thanks Dave I’ll give it a shot appreciate the reply I was looking threw this post and I cleaned my starter as well thinking it would fix it it cranked a bit faster after I cleaned and installed it but after attempting to get the car started it would crank slow even with a new battery by any chance can I get a photo of your ground locations might consider replacing them as well

Okay Joe- so check this out. My starter was dragging badly, and drawing down the battery, so I rebuilt it. I'm attaching some pictures... of course you can try to find a rebuilt one. It'll cost you money.

This is the crud that was inside my starter... I took it apart, not really hard if youve got an aptitude...

this part I should know whats its called, but its basically copper contacts, magnets and windings and they have to be clean. A fine sand paper (800 grit maybe) or  a green scotbrite pad to  polish it.

this is better... it has to be clean, and the magnets and springs need to stay where they are. Dont mess it up, or break wires

this is clean- re-assemble

And Joe- scroll back to the earlier part of the post- I already posted the starter rebuild, and the remote start switch. The ground wire is under the power steering pump mounting bracket. It's a really simple circuit. You just have to take it all apart, fix everything (basically, that just the starter) and put it back together right. You've got 394 cubic inches of cast iron and 1964 technology. It has to be right if you want it to turn over. I don't have a magic bullet. I can get into my car tomorrow and make a post.

Thanks again for the reply Dave I cleaned my starter really well all the contact points looked to be in good shape I found a couple of grounds just unsure if that’s where they go and if they need to be replaced there’s one behind the engine to the firewall,and the negative battery wire to the block under the steering pump then there is one that goes from the chassis to the control arm but someone tied an extra ground on there so I’d like to have everything exactly where it goes I’m new to these older vehicles just want to take good care of it lol

E-Bay is the best place to look for service manuals.
What year and model of car is this?

For some reason, Olds split their service manual into 5 separate books in 1964.
While original copies are best, they are hard to obtain.
Here's a link to what E-Bay has;

Here's a link to an on line source for the complete set of 1964 Olds Service manuals. It's PDF format, for $20

https://over-drive-magazine.com/prod...ervice-manual/ It says chassis, but it's all 5 parts, the complete set.
