After researching it I believe my oil pressure light might be related to me replacing the distributor and immediate oil pump shaft. I could not get my car to start so I replaced the distributor with a new one. When I removed the old distributor the immediate shaft came up with the old distributor. So I replaced the shaft and the distributor and now the oil pressure light comes on. I timed the engine after replacing the distributor at 10 degrees BTDC. When I first start it up the oil pressure light does not come on but after about 30 seconds it goes on and off and after about 3 minutes it stays on so I cut the engine off. It won't restart. I wait until the next day and it starts up and does the same thing.
