Well, as I mentioned a bit earlier in this thread the E300 ran fine on Saturday after a few miles of 'flakey' running. I did not run the car at all yesterday. Today I went out started the car and backed it out of the garage to sweep the garage. The car started right away any ran a bit rough for about three seconds. I left the car running just to see what would happen. After about a minute and a half it started to run very rough. It ran like this for almost a minute. I decided to get back in the back to 'nurse' the pedal to see if that would make any difference. The engine quit before I got in the car and it would not restart. I open the hood to find that the fuel lines had not fuel in them.
The CEL is now on, but I have no idea what the code is at this time. I hope that this will be fixed with the K40 relay when it arrives. Right now the K40 is to arrive ‘overnight’ this Friday and then I am to leave Saturday morning for Indy. If it were not for the fact that I have the relay ordered (and hoping that this will fix the problem) I would call the dealership and have them pick up the car. I would have a loner for the weekend, but it would be a C Class and with the current plans the E300 would be packed pretty tight.

What does the IFI stand for? I am just curious as to how this car works. It has an IP not much unlike the one on my 300D. Why is there not fuel in the lines? Is there a separate fuel supply pump? Sometimes I think that the engine control on this car with a mechanical IP is more complicated than a common rail injected engine.
