260e Engine Stalls And Cant Restart
 

Hi, I need help please.
I have a 1987 260e / 300e 2.6 My car has been bothering me big time for the past 2 months. The problem i am having with my car is that it shuts off on me while i am driving. I get a bulb light out and the antilock lights are lit on my display panel n then my car stalls. after that i cannot restart my car. I can restart it the following day due to my battery chargin itself overnight and then it shuts off again. I have replaced my battery and it is brand new. I have replace 2 alternators already and both giving me the same problem. The alternators are rebuilt alternators that i bought from a local autoshop. Can some1 please help me n let me know what they think? Are they givin me the wrong alternator? or can it be something else? also i did a voltage check and my car off is givin me 12v and wheni start da car its still giving me 12v. PLease help and advise me
thank you again.

I'm not a huge expert on these cars, but maybe 2 considerations are the fuel pumps and/or the OVP relay.

If and when you get your car started, crouch down in front of the passenger side rear tire and listen for a "hissing" sound. That is your fuel pump.

If it's making a noiser "buzzing" sound, then it might be on it's way out.

What concerns me is the indicator lights, which is symptomatic of a charging problem. The fact that you are getting a 12V reading with the engine running indicates that you are getting little to no charge to your battery...which would probably suck it dry in a day or so.

A normal charging system will read 13.5-14.4V volts at idle.

You need to find a different source for your alternator purchases...
