[QUOTE="Photojeeper, post: 430173, member: 19686"] 1990 YJ with Mopar Fuel Injection. When the engine gets to operating temperature the starts hesitating, when I press on the throttle t gets worse then stalls. I’ve replaced the fuel pressure regulator and fuel filter. Also insulated the fuel lines to prevent vapor locking which was a problem. The fuel pump is in the gas tank. Thinking it now could be a fuel pump having an issue. Will test the pressure. Any other thoughts? [/QUOTE]
