i have a 2002 mercedes cl500, whilst driving it one day car started to lack power like there was no fuel in it (missfired), drove it home and car wont start. called AA and there diagnostic said its misfiring from cylinder 1 and 2 but most cases its coil pack.
i changed coil back still same problem, had Mercedes specialist come out and they said the fuel pump not giving enough presure henve why it feels like its out of fuel when driving the car. i replaced the fuel pump still same problem.
Car been left parked for a month or 2 now it wont start tried jump starting it but no luck...Any help
