2002 mb slk 230 intermittent no start problem. Starts just fine but 1 or more times in a week it will not start, have power but starter dose nothing, hook up jumper cables and it starts.

When the truck wont start, bang on fuel tank to shake the pump. If it starts, replace fuel pump. 60 psi is what you should see with good pump. Less than 55 it wont start.

Its a hot start issue.

Can be related to low fuel pressure or problem with crank sensor.

Also it can be weak battery or starter.

But possibilities are to be inspected to confirm what exactly it is.------

To troubleshoot and confirm the issue,i suggest you refer few solved help links with similar types of problem like yours:------

Have you checked to see if there are any error codes with an OBDII reader? With those indications, there should be so errors generated. It will give us a place to start looking!

But if there isn't an error code - something is drawing maximum power, and it is probably the starter or starter solenoid.

you need to replace the starter before it leaves you sitting stranded somwhere. intermittent problems with the starter means most of the time the starter is going out. for futher help call 419 689 1114 and i will be happy to assist you.

put a volt meter on the battery when you get the problem to occur, I have run into intermittent problems and found that when cranking the battery voltage drops below 9 volts and when the voltage drops below 9 the pcm powertrain control module does not know what to do and will cause the problem you are talking about, if it drops below 9 volts check and clean power and ground connections and have you battery tested, your local autozone will test it for free, and most likely your battery is going bad. and auto zone installs batteries for free also.

check the the ignition switch plug on the opposite side of the ignition switch on the steering colum

Hi the fault code on your car means P0714 Transmission Fluid Temperature Sensor Circuit Intermittent. Hope this helps.

sounds like the ignition switch isnt signaling the solenoid all the time try replacing ignition switch or test the small wire on the solenoid i think its purple when it wont start with a test light clamp on ground n probe the small wire with key in start posi=tion test light should lite if not i would replace ignition switch
