Why after changing plugs wires car won't start it turns over but then does nothing and when turning over it drains the battery battery was unhooked when this was all done. Any one got any Ideas

did you go plug for plug and HT lead for HT lead or did you just pull the lot and then replaced the HT leads
If you did this it is very possible that the firing order is messed up
next when you pull a battery you energize the immobilizer system
you will probably have to use a scan tool to reset the system
make sure battery terminals and posts are shiny clean and tight

I need a Mercedes clk 240 reg 05 user manual

If you are looking for user info to operate properly, you can likely get the info from a service like "All Data" ( ) They are an on-line service/repair manual supplier.
If you're looking for the factory manuals, I'd look on Ebay or similar sites, check salvage yards, used book stores (maybe find a store who specializes in car and truck literature) and car swap-meets are a GREAT source for manuals. Good luck!

No spark at spark plugs

The absence of spark or HT on the spark plugs is due to a failed IGNITION SYSTEM. Now this can be traced very easily. All you need is a 12 Volt park lamp, or a multimeter to check the voltage on the HT coil. you need 12 volt on the + side when the igntion is switched. if not check the fuse. Now on the other side of the coil you must have the voltage grounded ( switched by the igntion system) to produce the spark. If there is no spark the HT coil is a suspect. If not the ignition system is not switching and must be checked. failure of the electronic unit can be the reason , or lack of pulses from the pick up can be the other reason . You must be able to easily find this out by simulating the device to confirm, (feed a pulse) .

Hi, sounds like you have a spark tracking problem caused by damp etc, worth spraying all HT system with something like WD40, if that stops it going on to three cylinder it will prove you need to renew parts of your HT circuit etc, good luck.

Start engine won't go . Romeve Ht wire attach to

To do accurate testing you will need to get a chiltons or haynes manual and follow the procedures listed. The system is not terribly complex but guessing will cost you money. Before testing, check coil wire and harness connections to make sure they are OK. If you need advice concerning any part you tested just ask.
