HI lads anyone got any info on changing the fuel filter om a 1998 320 ML;)
 
cold start

Please tell me wat ive not done. mercedes 1998 320 ml .the car is a nightmare on cold starts, it runs eventully, when it starts after about 30 cranks, today on the first crank i inspected pressure, there was pressure there with fuel,
i disconected the fuel line, from the filter, and on 2 cranks the jar holding the fuel was half full, so it cant be fuel starvation? its had a new mass, plugs, leads, coils, are ok, ive diconnected the temp sensor , comes up with the code fault, a bad cps would throw a code as well, but thats my next move,
ive also cleaned the throttle vale and its ok, hoses ok no leaks etec, etc,
am i missing something?

The CPS measures 1kΩ when good, only the 2 connections on it if you can measure it. They often fail once warm, but there is no reason why when they are cold £48 from Bosch or £87 from MB
