Engine cutting off mid drive- 91 chevy silverado 1500

Asked by himynameiscapote Jul 11, 2015 at 12:55 PM about the Chevrolet Silverado 1500

Question type: Maintenance & Repair

1991 Chevy Silverado 1500 flare side 5 speed manual tranny

Ive had the truck for just over a year now. When i first bought the truck it had a slightly rough idle. I've replaced spark plugs & wires, Heat sensor, Ignition & distributor, battery & alternator. It idles perfectly and drives much smoother than ever before but for some reason the engine sometimes cuts off mid drive and than wont turn over when i try to start it. After some time i can sometimes get her to crank up again and occasionally start.

Ive heard that it may be a burned ignition coil but after removing it and testing it, the ignition coil proved to be in working condition.

Fuel injectors have a nice even spray so i don't believe it could be fuel related but i have been wrong before.

Running out of ideas. Thinking about replacing the starter and single valve temp gauge next. please let me know if you have any suggestions. would love to get this issue solved once and for all.

Did you change the 2 wire or 1 wore temp sensor. The 2 wire one is for the computer, that's the important one. The 1 wire sensor is only for the gauge. I want to make sure I understand it correctly. When it shuts off the starter won't even turn? Does it try or click? Does anything electrical work or not work?

Sounds like you have a bad distributor cap with a crack allowing spark to the block so your ecm is shutting down until the static charge goes away. Definitely sounds like a bad spark issue. Had this happen in an 88 Cherokee. Start the motor in pitck black dark at arount 2,000 rpm and search for an arc.
