No codes present in computer. Good fuel pressure. Good compression on each cylinder at 100psi. Getting spark. Engine won't start unless you run the starter for about 20 seconds. Is it possible for a clogged cat converter to prevent the engine from immediate start, but run OK once started? If not, any thoughts? Thanks

If it runs fine after starting then cat converter would not be the problem. You could try the fuel filter or fuel pressure regulator. When is the last time you gave it a tune up?

After additional research online, a coolant temperature sensor gives these symptoms and not fuel. After changing it, she runs like a. Champ.
