hi
first post. new to pontiac montana's. not new to forums
so here goes.
i had the head gaskets replaced in the van. montana 03 250000KM
i had a egr piece on the exhaust replaced. last week
yesterday i started the van, battery light was on. shut off and will not start
crank for a while the whole time lights blinking on dash and in cabin. then after about 20sec nothing
brought to shop it started right away. they said bad battery and replaced it
this evening i started van no prob went for short drive. no prob back home shut off. 5 min later start again. battery light on. shut off. now the same thing no start same symptoms. i have searched threads and could not find similar prob

sorry to hear about van(cause I have an 03 also) do a search in this forum ,from what I remember one of the members had something like a bad crank sensor wire that rubbed it self open or was shorting against something that was causing a intermittent no start . It may or may not pertain to your problem but a start. Good luck and keep us posted/educated.

also is it throwing any codes or have any stored in the computer ?

did the shop that replaced the battery check the charging system?

it seems that they never checked the charging system.
it seemed wiered to me but anyway i got her to the shop and they say the alternator is shot, only putting out 7 volts
any way new one tomorrow so we will see
thanks for the replies

just to keep anyone with the same problem up to date
it has been over a week and it seems that the main problem was the alternator
now except for a problem with a VERY squealy drive belt my van works fine

glad to hear the van is back on the road , check the alternator to see if it is lined up correctly or your belt is worn .
