hi i have 01 cls 148xxxmil. at the shop they change my timing belt test drove it working good came back from test drive turn the cart off and it wont star any more.....NO SPARK they worked on it for three days,and called me with bad news my valves are bent. well i put new engine with 30.xxx...... still wont start check my spark, there is no spark called dealer they think something to do with the wires.....ANYBODY PLEASE HELP...

 

so they messed up timing after service and they replaced your engine on their cost ? any codes ? they must have done something wrong like wiring i think

 

no i did paid for new engine and i replaced it my self, and no codes

 

so they messed up your engine doing a timing belt change and you had to paid for new engine ? thats sucks man

 

You need to check wiring for crank sensors @ front cam and crank shaft. You got have open circuit between ecm and one of those sensors .... or in the worst case scenario some wire got pinched ,shorted and fried ecm . Check your wires first , i think they stretched wires for crank sensor located @ crank shaft as it is kind of short if you misplace it during reassembly

 

Finally got it... It's working

 

what was it? Is your old motor good too?

 

yes my motor is good,i have no idea what was it,i unplugged all wires from every fuse/fuse box and when i plugged everything back it still nothing, so decided to unplugged just one wire connection that located behind (ignition fuse)(left door) with unplugged wires car started,plugged everything back in and no more problems.....

 

The dealer messed it up. Should of shoved it to them.
