on going saga

1989 300e. would not start. did not hear the fuel pump energize. replaced fuel pump relay and it started and ran well for a week or so. then after reaching operating temperature, would stall and not restart until it had cooled down some. replaced the coolant temperature sensor at rear of block. ran well for again a week or so. then started the stalling and not restarting thing until water temperature fell from the 82 degree mark. then replaced the ovp relay as last resort. same condition. won't run after reaching the 82 degree mark. once the temperature drops to say 60 degrees, starts and runs fine. till i reach the 82 mark. anyone have any idea as what to try next? thank you. and happy new year to all.

Why did it run after replacement of fuel relay? Is the replacement a new one or a used one? The solder points on the relay's circuit board get circular cracks on them and can open when the engine compartment gets hot.

But if the relay replacement is new then I doubt if the relay is the problem. To check for cracks use a magnifying glass.

not a cool car

this is my car that my dear friend is trying to repair for me. everything seems to work so well and just this one thing keeps it from being working vehicle--once it gets hot it just shuts down. this has been happening for quite awhile. at first it would not restart once i had ran it for awhile, turned it off and then tried to start it again within a shart time. now not only will it not restart when the engine temperature is over 80, it will sputter out when i step on the gas. one of you smart people out there must must know the answer to this problem. yes?
any help sure would be appreciated.
thanks and happy new year.

finally

local independent replaced the distributor cap and rotor. fixed the problem identified above in first post. evidentally the 'resistance' would climb to unacceptable levels once the engine reached operating temperatures. now i know. and happy to share.
