1990 GMC Vandura 2500
I have a van that I was driving and it started getting hot,
but it died at a stop light before I could get off the road.
Since then, I haven't been able to start it without starter
fluid. It will run while I'm giving it gas, but then dies. I
don't know a lot about vehicle repair, so I don't even know
where to start. Can anyone point me in the right direction?
First thing is run a compression check, if it got hot enough to die on the road chances are very high that piston ring damage has occurred, in other words the rings lost thier tension from the heat. So your compression will be low and the starter fluid adds just enough extra flash to get it running but won't maintain combustion when the incoming fuel mixture drops into idle circuit. Note there maybe other engine management componets also damaged by the heat but you won't find that until the engine is back operational specs.
Thank you. I won't be able to get to it for a couple of days but I'll try that out.
