Default running issues

so as some may know my buick has been having issues recently...The most irritating it will fire up run and drive for no longer than 20 mins strait...Then you had to wait about an hour or better for it to restart...back when it was my car it threw a code at me for cam position sensor so i replaced it today and it helped but still not fixed..Im thinking ICM...Opininons please
Also does anybody have a diagramn of the OBD pinout for a 90 lesabre so i know what terminals to jump with paper clip as i am getting SES lights...my only accesses to a OBD1 scanner si 25 miles away and will take me an hour to drive it there lol

Would this be right ?

Sounds like something is over heating and that'* shutting you down. Have you tried unplugging the MAF and see if that helps any?

icm or cps have done that to me but neither threw a code. when my maf when it just ran like a carb car with the choke stuck on. usually something like that has to be attached to the engine to get heat soaked like that. if you got a heat gun you can warm these parts up faster to facilitate easy trouble shooting.

and ya thats the normal old obd1 if thats the setup the buick has

Heat it up with a heat gun and see what happens.

you dont need a scanner just jump A and B.

and heat guns are cheap and have lots of uses

Please remind us what the buick is..

Potentially crank sensor etc. Have you checked fuel pressure etc?
