Customer Question

I have a problem on a 2000 E320 it cranks and runs for 10 seconds the most then dies,usually it's more like 2 seconds running,i changed out the cps and it started and ran for almost a minute then just died again,i have fuel pressure and no codes,weird thing is if i step on the gas it instantly dies also i took off the MAF and it looks clean,left the MAF off and started the engine while blocking the intake hose and it ran for as long as i blocked the intake hose,anyone have any ideas?

Hi, it sounds like either a shorted MAF or a huge intake leak. Can you substitute a known good MAF for testing?
Customer: replied 6 months ago.
I checked that I changed the map and the csp. I have no leak in the intake
