Starts when cold, dies when hot and won't restart

Asked by Sep 11, 2016 at 01:44 PM about the 1994 Jeep Grand Cherokee Laredo 4WD

Question type: Maintenance & Repair

I have a 1994 grand cherokee laredo and it will not
stay running unless the engine is cold. It will start,
but as soon as I take my foot off the gas it dies,
unless it has been cooled down for a while. As
soon as it gets to full temp, it wants to die again,
and if it does, it will not restart without a LOT of
forcing the ignition to turn over, and then it is
impossible to keep running.  We replaced the crank
position sensor and the throttle position sensor, as
well as all three of the coolant sensors (we were
getting an error message saying coolant sensor
bad, and it's still a hoping even though they've all
been changed, so there's that also), but none of
that fixed the problem. Any advice would be greatly
