Engine Mechanical problem
2000 Chevy Silverado V8 Four Wheel Drive Automatic 86,000 miles
----------------------------------------------------------------
Is there a known problem with the 2000 Silverado's leaking coolant into engine? The truck just all of a sudden hesitated and then stopped running as if it ran out of gas but had gas, and it will start right back up but doesn't stay running long. Thought fuel pump, but someone suggested I check for a clog in the cat converter,and was told it is a known problem with this year/make. I don't want to spend $$ on the wrong thing. Ideas?

If its leaking coolant into the engine you'll be overheating the level on the radiator will be dropping and not enough coolant to remove the engine heat this is the whole idea.

The best scenario here is do below and see what happens.

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light.

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time
