Hi, recently I acquired a 1990 190E 2.6. I am new to BW and this is my first MB. I've had it for about six weeks and have only replaced the shocks, brakes, and battery. It was running great. I went on vacation for a week. On my return, the car started but ran really rough.. The next day it won't start at all - cranks strong though. I tried starter fluid into the intake and it still won't start. I've ordered new fuel filter and injectors. But, if it won't start using starter spray, I don't expect the filter and injectors to fix it. I will get new spark plugs too. Any suggestions or things to test? Thank you.
