1989 gmc suburban won't stay running

Does it start right back up, or does it need to cool down a bit first? I would check for spark on a spark plug wire when it shuts off. If no spark, it could be the crank position sensor. If there is spark, check the fuel pressure.
Have you checked for trouble codes? Here's how:

Then you have a failed fuel pump

Can you hear it run if someone is back there
& you cycle the key on & off

Check fuel pressure with a gauge on engine port

Almost half the people here this week need to
buy a fuel pressure gauge.

Before you start taking apart your dash make sure that your vehicle speed sensor is working. It should be attached to your transmission. Hope this helps.

87 gmc sub runs for a while then dies


I had a 99 Suburban that did almost the same thing, it turned out to be the Catyletic Converters were plugged. Try taking the exhaust pipe loose at the manifold for test purposes. If it runs good with the pipes loose, that's the problem. Replace the Cat's. There were no codes for either, it would start and run nice for about 5 seconds, then run rough and then stall.

If it has injectors it has a ecu, if it has an ecu it has a diagnostic port (normally under the drivers/passenger dash) if you look down at seat botton level you should see a small black port) You can go to any auto zone or parts place and they will scan it for free. You may have a head gasket issue with overheating or your cooling fan(s) may not be turning on. Check the codes first
