What causes a hard starting engine to go cold?
Even more, the computer uses information from (ECT) and other sensors, to adjust ignition timing as needed. A hard starting engine when cold, is usually associated with certain components; when they begin to fail or wear out. Although not exclusive to this condition, the following components, are worth checking:
Why is my Chevelle 350 hard to start?
Fuel pump check valve doesn’t maintain pressure in the fuel rail so it boils and then you have to crank excessively to get rid of the vapor before it will start. Bought a 1972 Chevelle 350 a couple years ago. Every time I drove it it wouldn’t restart easily or sometimes not at all unless I waited a while.
Why do I have a hard time starting my car?
There are varied reasons why you may have a hard time starting the engine; when cold or hot; This is perhaps the most common fault to appear under this condition. You may notice the starter motor not working as usual or weak. Check your battery first. Then, have the starter motor tested, if necessary.
What kind of starter do I need for an 89 F350?
You can also bolt in a 351/400 starter. Good starter cables and battery and your good to go except for bad modern gas which has a tendency to boil easily. So, I have an 89 f350 with a 460 block.
Why is a hot engine hard to start?
Most of the reasons by which a hot engine would be hard to start are based on problems related to the fuel. When the engine is too hot, fuel can’t circulate properly due to the way in which vapor obstructs it and therefore the engine wouldn’t start as easily as it should or it wouldn’t start at all.

Why does my 68 2 barrel engine get hot?
If you hook up an electric fuel pump, it will put the fuel under pressure and raise the boiling point. My 68 2 barrel did exactly the same thing. Ive not had any problems after putting a phenolic spacer under the carb – but I switched to an aluminum 4 barrel intake manifold and edelbrock carb.
