I have a 2001 bravada (all wheel drive, automatic) which my son sometimes drives. I also have an 88 Volvo which he usually drives. He had been driving the bravada occasionally and reported to me that in...
starter is bad, (if it spins up fast and the crank shaft is stalled its a bad starter (battery charged 100% and good)
problem 2 is called low idle and will cause stalling
there are vast ways to stall any engine, (i will not list them)
1: egr stuck open , stalls at all stop signs.
2: isc stuck closed,
the former is harder to save the stall with right foot actions?
the later is childs play, (you are now an ISC)
that starter can in fact fail in many away.
Shorted (over current and causes solenoid to drop out)
open, starter, its dead as a door nail.
bad solenoid. causes free running of starter, it spins up real fast
and the engine crankshaft is no moving,
this is a bad solenoid or just a dirty shaft for pinion.
solenoid main contacter, bad, intermittent starts. or DEAD.
the contactor can sieze, and engine keeps cranking
this is a horrible ugly mode of fail, the engine can infact
destroy the starter (100HP kills 5ph starter by going over speed.)
theres is a clutch in the starter that prevents this, but it to can fail
or get dirty and jam.
if you were to say exactly what the starter did,. step by step
we can answer the why>?
i turn key, the starter spins ,but not engine
or same and its too slow
same and it only clicks
or same and when i release the key the starter is still making noises...
