Start error mercedes sprinter 2001
New owner . Cleaned van yesterday, with cloth and
bucket no hose. Van started as usual. 2 hours
later. Start error. Key turns all positions. All
dashlight, lights accessories etc working. Visual
check of fuses. Ok. Charged 25 mins off another
vehicle. Jump start. Still start error. Have tried all
tricks on all forums with key fob sequence, battery
disconnect.etc. no access to volt meter. 100km
from dealer or mechanic. Any suggestions to
override or repair to get running to get to dealer
with star diagnostics?? Thanks in advance
