Starting Problem on 90 Buick Park Avenue

[ABarn10708]

I Have have a 90 Buick Park Avenue that has recently had the problem of not
starting after it runs for awile. My OBD1 shows no error codes and there are no
Temp Lights. And I have check the coolant level. It seems to have to cool down
before it will start Again. Can anyone help me?

My '91 Park got the same way. Have somebody investigate the crank sensor, which
is somewhat below the water pump. If the water pump leaks onto that sensor,
then it craps out and either fails altogether or else it fails intermittently
when a certain engine temp is reached. Replace the sensor.

Which motor? My crank sensor is on the back of the block.

Sounds like it's that, though. Same symptom for me... it was the crank
sensor.

You can test for spark while it's not starting. I bet there is none.
