Ford 289 Hard Or No Start When Hot
Q. I got a 1927 Ford. It has a 1964 Ford 289 V-8 in it and an automatic transmission. My question is it will not rum more than about 8 or 10 miles without having starting problems.
The first time it happened they said I needed a coil. The next time I drove it about 8 miles it sat a while. It would not start. I had it towed. These people said the electronic distributor needed replacing. We did that.
The next time I took the car out I went to a friends house 10 miles away. We talked for one hour. The car started hard but it started. But just as I got home it quit running. It has gotten so I will not even drive the car. Someone said it might be vapor lock? Can you please help me?
A. Vapor lock would not cause an engine to die while you are driving. But that doesn't mean you don't have a fuel problem.
We need to know what is missing when it won't start, fuel or spark. Next time this happens, pull a spark plug wire, put in an old spark plug gapped to 0.200" and lay it on a good ground. Crank the engine and see if you have spark. If it doesn't, then we need to look at the ignition system.
If it does then we have to look at the fuel system. Have someone turn over the engine while you squirt carburetor cleaner into the carburetor. If it starts and runs, then we need to suspect the fuel pump or carburetor. Fuel could be dripping out of the carburetor into the intake manifold and flooding the engine.
Also check the ignition timing. If it is set incorrectly it will make it hard to start when it's hot.
