- 01 mercedes-benz c320 M112 V6 GAS ENGINE
Hi group I need somebody to tell me how the 2 fuel pumps operate and what to check on a 2001 mercedes-benz c320 engine model M112 V6 3.2L gas engine. All the gas end up on the left side of tank right side empty out. Both the fuel pump run and I recheck the hoses inside that how I found out ride side was empty I put gas in twice about a total of about 6 gallons of fuel. The Fuel Pressure Gauge on the fuel rail read 0 but the bleed line on the Fuel Pressure Gauge showing drops of fuel with a lot air when pushing the button in on the Gauge also I have jump the relay plug to get the fuel pumps to run. I check to relay it seem good I think it a wring problem not grounding the relay.
I had the front fuse box out and computer hardness unhook too so I could change the hood cable look like it was going brake soon the fuse box was in the way. What I done it started with the gas tank leaking. had to take out the fuel tank to change it. but couldn't find a used tank anywhere. I already got the fuel pump out the hoses and wring out too because I thought I could find a used tank. So I'd plastic welded the tank for a small hole on the left side not leaking lucky now since I couldn't find a tank. To get the tank out I had major job had to drop rear sub frame, replace the whole exhaust system because it was rusted thought that meant I had to move the oxygen sensors to the new pipes. also change all bushing in rear suspension there were also shot. If I know it needed all of this work and money I should it junk it. please help me with any information that might help thank craig
