Fatcat,You didnt mention what engine you have.
When the no start occurs, try holding the gas pedal all the way to the floor, hold it there and try starting the car.
If it still does not attempt to start, disconnect (1) spark plug wire at the coil and have someone try to start the car, you should see and here a "spark" jump and snap.
If spark is present, air inlet to throttle body or carburetor and check for presence of fuel.
Let me know what you find.

Check to see if your electric radiator fan is turning on. These cars are known for the temperature switch that turns on the fan to go bad. Also, a highly overlooked problem, make sure the fins on your radiator and condenser aren't blocked with debris. Shine a flashlight on the opposite side and look through. Good luck!

Hi. This issue has several causes, but the oil light indicator is a strong sign of low pressure in the engine. This will cause the engine lubrication rate to drop, thus, producing a illuminated oil light, and erratic Oil pressure readings. The necessary actions are to have a manual oil pressure test ran on this engine, asap. When running a manual oil pressure test, you will discover if the true oil pressure is low, or normal. If the test proves that the oil pressure is, indeed, low, this will confirm that the Oil pump is suspect.
Now, if the true readings given during the manual oil pressure test are indicating that the pressure is normal, this will be the result of a failed sending unit(oil pressure switch). Although the oil pressure is suspect, this is not your only issue here. There seems to be a abnormal compression rate, present. This is causing the rough idle, and erratic RPMs. I recommend to administer a engine block compression test, as well. This test will discover if , indeed, there are issues within the cylinder heads, and block structure, such as a worn head gasket, cylinder wall issues, and cracked block. Normally, these issue will send signs, like white, or gray smoke out the tail pipe, or discolored oil. It will, also, promote erratic RPM ratings, and a rough idle. Have the oil pressure test, and engine block compression test ran, asap.
Once the test are administered, you will be able to isolate the actual problem areas, more accurately. Check the spark plug wire sets, and ignition assembly for faults, also.
