please help.
my ml320 model 98 was parked in a very good condition.
the day after i tried to turn it on with no success. new battery, the truck crank very good but it wont fire up. i have no spare key to check if the key code is lost by the DAS or not.
1- how to check if the key is still recognized by the DAS?
2- does the module keeps on sending order to the fuel pump to delivery fuel or not if the DAS lost the key code?
3- does anything is responsible to stop the pump from delivering fuel as the Flying sensor?
4- how to check if the fuel pump is ok or not?
i appreciate your soonest reply.

If you have the smart key - then if it allows the steering to unlock and the key to turn in the receptacle - the key is good and the car recognizes it.

If the engine cranks you don't have a DAS issue. Crank position sensors are a common cause of crank/no start complaints. Keep in mind that a faulty CKP sensor will cause the fuel pump to shut off!

thanks a lot for your quick feedback, i cranked the engine with the fuel pipe loose there is no fuel delivery, the cause was the fuel pump FUSE and RELAY. my car is running again once i replaced them.
once again your effort is much appreciated thank you "Zulfiqar" thank you "ILUVMILS".

hello, my fuel pump relay keep on burning over and over again.

Failing fuel pump drawing high current or wiring that's chaffed and rubbing on the chassis.
