CHEVY RUNS THEN DIES

1989 Chevrolet Suburban

Engine Performance problem
1989 Chevy Suburban V8 Two Wheel Drive Automatic 120, 00 miles

After driving the suburban for awhile during the day and it behaving fine, when it was driven for a pizza run that night it only got about a 1 1/2 miles up the road before it died. Cleaned battery cables after about 1/2 hour (tools needed to be delivered) and started right up. Same thing happened. This time got another battery, started back home, went about 3 miles this time before it up and died. Starter was replaced about 6 months ago. Help.

Next time it dies out

If the engine's condition is in tip top shape-do below to determine if its fuel or spark problem that's if its cranking over and refuses to start

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
