Hi all. I need some help. I have a 91 240. After car warms up my car will die. I have had it die while idle, while accelerating, or while putting in gear after parked.

I have replaced fuel pump(external), fuel filter, in tank pump, strainer, fuel pressure regulator, and fuel relay.

What am I missing? I am losing sleep over this. Please any help?

 

Update. So after driving around for a bit pulled over left car in drive with foot in brake. Less than two mins later, car died.

 

replacing random parts without first diagnosing whats causing the problem gets expensive fast.

 

When it dies - does it start right back up? If not, check for spark and fuel at the rail.

 

you could check the condition of the distributor cap + rotor

 

Pretty sure, like 99%, that you need a new CPS Crankshaft Position Sensor... Buy an OEM.
