Hey Bob==You don't say what kind of car it is but if it is a GM it can be the torque convertor needing a new solonoid. GoodluckJoe
it is a 1990 420sel mercdes benz
No. A bad starter would cause the car not to start.
Bc is not enough air in the intake....
My girlfriends 97 was doing the same thing....it turned out to be the ignition switch.It started to stall intermittently (once every couple days)then yesterday it would not run at all unless you held the key in start position. Take a test drive and giggle the key to see if it shuts of.
prob a vacume leak
Maybe a throttle positioning sensor? Is it hard to start? Does it start then stall?
No it cannot unless alternator is not charging the only power a diesel requires is for fuel cutoff solenoid
If the check engine light has come on, have the codes read. That would be a good place to start.
check for clogged fuel filter, or faulty fuel pump
There would be a spark plug loose n it wiggled and it got back into place and started back up
Check the crank angle sensor usually about $150 to replace
could be a bad fuel pump or fuel filter. have a friend crank the car as you bang on the fuel tank.this can some times free up the trash on your fuel pump.
AC runs on the battery. If the car is off and you run the AC, then start the car, it will stall.
