sounds like canada or USA car, is it?
i just restored one, know it like back of hand.
no inertial switch, of any kind, no upside down car switch. like my mazda either. and that cuts fuel not spark.'
want to trouble shoot it or guess and go broke?
no spark, clear as day, and the ECU cuts fuel with no spark.
so forget fuel. totally.
r
eady to fix spark?and you said no spark but failed to say,
at the coil or all 5 places. big deal that....
the ECU will talk to you, and tell you why, 1/2 the time.
is your tachometer dead, cranking> 4x4 have tach.
and will move to 0.3K rpm that is 3/10s of below 1 mark.
the 1 means 1000, so 3ths is 300 rpm. cranking. does it?
if not the ECU will throw,,no spark codes, 2nd clue.
what to learn?
http://www.fixkick.com/IGN_timing/no-spark.htmlfirst check for spark that the ignition coil. center tower.
how:
in 1991,in the USA the spark creation changed, radically
the ECU generates park, in this way.
CMP in dizzy makes cam signal (there is no crank trigger in 91)
the CMP makes perfect square way
the ECU sees that. and triggers the ignitor
the ignitor charges the coil, and spark happens at the coil tower.
does yours?
if the eCU sees a missing CMP signal you get code 41.
if the ecu sees missing spark read back, code 42
you must crank for 5 seconds release the key to see codes of this type.,class.
do you know how to use the diagnostic jumper paper clip yet.
ask here for interactive answer.
