SeaCoupe

Car started acting funny. Didn't want to accelarate. Now it simply won't idle. Pressing the gas makes it worse the car will die quicker. I cleaned the maf, nada response, left maf unplugged, nada.

The code refers P0113 - Intake Air Temperature Circuit High Input. That means that the MAF is telling the ECM that the temp is below -30.

However, when I unplugged the MAF so that the car could run at the preset values, I got no improvement.

I hear the injectors clicking, but I think there is no gas pressure since I can't hear the fuel pump prime when I put the key to on. Can I check for pressure by releasing the pressure on the line at the fuel rail? (of course my hearing is not so good)

I have an extra maf I can try. But I think the code I am getting is a byproduct. Realize, this happened immediately after stopping to get gas. I only put Chevron Super in the car.

Thoughts?.

Can someone post up the WIS for replacing the fuel pump in a 2002 C230 Coupe?

Thanks.

Ed, for a man of your talent replacing the fuel pump & sensor unit under the round cover drivers side rear seat is a walk in the park.

Maybe John or Karo can post the WIS method for you.

Out to grab the laptop now. I'll post the WIS in a bit.

Ed,

I posted the WIS in my thread from yesterday: https://mbworld.org/forums/c-class-w...ment-tank.html

The fuel filter and pump are the same.

John, SeaCoupe is asking for instructions for a 2002 C230 Coupe. The fuel filter in a 2002 model is mounted outside the fuel tank.

However, the instructions for replacing the fuel pump/sending unit are still applicable for 2002 model.

johnand

I know. He wanted the instructions for replacing the fuel pump which is the same thing as replacing the filter for us 2007 guys

Ed,

Attached is the WIS for the fuel pump specifically. Also found out us US guys don't need the fancy claw wrench. The sending units have a latching cover. Attached the WIS for that too.

I have a 2007 c280 and went to replace the pump and the one I bought matches these instructions and Amazon says I got the compatible one, but upon opening everything up, it is different?

Doing some digging into the 2008 c300, it looks the same as the one i have.
