92 300e died no fuel at injectors
Driving my 92 300e yesterday, it died under acceleration. Using known good[new] parts, the overvoltage relay, fuel pump and relay, fuel actuator on CIS body, and the "MAS" box have all been ruled out as problems. There is fuel under pressure reaching the CIS body, as well as being present at the fuel actuator. It would seem likely that the trouble is somewhere in the CIS box, but where? Anyone have any ideas? This car has only 88,000KM on it. Thanks for any help.

hey man,
if you have the correct fuel pressure at the cis unit, and the correct voltages going to it, the find a cis unit at a boneyard or if you can afford it, a new one. Check all the electrical first though with a voltmeter with the specs from a repair manual or cd. Otherwise take it to a shop. On my 88 300e, the fuel pump relay went, but I took it to the dealer(idiot!), 2k later the thing still dies twice a month randomly. I bought a fuel pump relay- wallah! hope this helps.
