Got a question about starting my car. Its a 1990 500SEC. Heres the thing, when the engine is warm the car ALWAYS starts without barely turning the engine over, as i would expect, but when its cold, the engine turnes over fires once....turns over a bit more.....fires again....turns over a bit more....(does this overall for about 4-6 seconds)then starts, and runs silently, perfect idle ect. Sometimes when cold it starts like when its warm, without hardly turning over once, but more often than not it starts from cold like this! Its as though its not getting enough fuel when the cars cold (like its not being "chocked" like you did with really old cars).
Ive only had the car a few weeks, and I purchased it off the original (seriously rich) owner, its got Full main dealer history and has been mantained regardless......so Im assuming its something simple thats gone wrong- I just dont know where to start!
Any ideas? Ive heard that the cold start injector might just need cleaned??? The local Mercedes specialist was NO help, firstly saying that the car was "getting on a abit" and that they would have to charge a full hours fee ....Â£85 minimum just to look under the bonnet, and wont even tell me where abouts the cold start injector is without looking.....the idiot mechanic at the desk reckoned it might need a new engine management computer (which is a load of garbage!)! I guess its because Im young they dont take me seriously with a car like this!!
Any help would be greatly appreciated....
