recently my '94 C280 would stall for no reason, at times i can just be idle at a light and it would stall other times when gasing it would stall as well. To start the car back up it could take up to 3-5mins from locking the car unlocking it, opening the trunk etc...im not sure if this is the process to start it..or just wait it out..h

anyways i replaced the OVP today and the same issue, right off the bat after replacing the OVP the car would not start.

i want to say this was a fuelpump issue but when the car does NOT start, i can turn the radio on there is a digital display but no music...also you cannot roll the windows down, headlights work...but no A/C or windows or moving the seats electronically.

Does anyone know what else could be wrong?

thanks in advance.

Question you have checked fuses up to 11/94 fuses20&21 after 12/94 build fuses 21 and 26 under hood. fuse 26 is tied to radio and seat relay. Or maybe an Ignition switch. Tim

Check that you have the new OVP fully plugged into the connector..you have to hold the harness to get a solid plug-in...

thanks, i'll give this a shot...i'll try the OVP again.

does anyone know the "Green relay" in the trunk of the car behind the battery has anything to do with this?

The green relay in trunk closest to spare is the k27 fuel pump relay,is fed by fuse 18 in trunk up to 11/1994. Tim

i doubled checked the OVP and it is all the way in...

could the OVP cause the NO radio (but has digital display), can't move electronic seats or windows down?
