A friend of mine has an early 90-s Dodge truck. 4 WD, and V-6 engine. throttle body fuel injection. Sometimes it won't start when it's cold. Spins nice and fast, but just won't catch.
I was there one time when it did this. Starter for a couple seconds. Wait a c ouple minutes as we chat, and then it fired right up. Says it's getting worse, and the problem is worse when it's cold.
He replaced the ignition coil. I ws thinking cap and rotor, but it runs fine after it starts. He says someone suggeste fuel pump may be going weak. Any ideas what the problem might be?
