93 mercedes 300te no start intermittent
I am working on a 93 300te that intermittently is hard to start. it cranks fine but is either not getting spark or fuel. it has a code 12 inthe sysytem but I lack a 93 manual to tell me what the code is.
we here a buzzing noisefrom about the air inlet and it will start, if no buzzing noise car will not start.we tap on top and it will start.
Any help would be appreciated.
