1993 300e Intermittent start issues
I have a 1993 300e that starts when it want to. The fuel pump is good as is the relay. The ecu intermittently sends signal to energize the relay. once the ecu has sent the signal it keeps the car running until shut off. I am thinking switch. The crank trigger would fail when hot or at all times. PLus I don't get that normal first burst of fuel when ignition is on when the pump signal is not sent on crank. Any help would be appreciated.

93 MB 300E cranks but won't start
Hi,
I am also having problems with my 93 300e, I left the car with wife and she went a couple places and told me first it took her 10 min to start, then that evening I had to go get her, car start after that day one time I took to fuel station and after fueling it did not start again, one day later, I went there it start again took it to our place and did not start again, I read the forum and so far I change fuel pump relay, and tonight crank position sensor and still cranks but not starts, I ordered cam position sensor, and read here about OVP relay. I will buy that too but I really need a code reader for this car, that 16 pin one, I also bought cd's they show the terminal but not tell any thing about how to read the codes with it, any bodies help would be appreciated. Thanks. |

Check the fuse on top of the OVP relay.

good idea. Fuse is in good shape on the OVP relay, mine is made in hungary, as K-1, K-2, K-3 schematic shows 3 diffarent relay function on it, 59 7238 000 is the number written on it, I try to brake it open but so far unsuccesfull, tomorrow cam shaft position sensor comes, next buy will be this OVP relay, then ... I dunno???

I also have a 93 300E but the wont start problem was something I had when it was 3 days old sometime in 93 and after the first 3 months of being at the dealership under warranty they took care of it... now there a modulating idle im dealing with.... im a little worried about the part numbers everyone is showing for the OVP control, mine doesn't match up... are the pics of the actual units or just website posts?
