Hi ,my sisters Grand Am has no spark.Have power to the ignition module,but no spark coming out,Have changed the module and coils from another car,and still get nothing.It is a 3.3 v6.Was running fine,she went over a set of railway tracks,and it quit.Have tried a code reader,but all that comes up is the diagnostic code 12.Any ideas would be greatly appreciated.Thanks.. :banghead:
Do you mean on the starter?.It rolls over fine.Not sure I understand,Thanks.
i had a problem with my car
take a knife and scrach a part of the engine block so you have a metal open spot
then take one plug wire, and stick a long screw in there. be careful to use a glove
hold the screw to the bare spot on the block
and have someone try to start the car
if there is no spark, replace the selenoid. happened to me and selenoid fixed it.
ok its solinoid
crankshaft position sensor is the signal to the ignition module to fire the coils
So are you saying to replace the crank sensor,or the solenoid on the starter?Is there any way to test the solenoid.Thanks guys,really appreciate your patience.. :smoke:
ignore the solenoid thing. if it turns over, you don't need one...
Does this mean it could be the crank sensor?.Thanks..
yes need to check the wires to the crank sensor as well
I am currently going thru the exact same problem. Replaced the ignition module, not it. I have voltage to the crank sensor but its weak, does anybody know if this is normal? Does it have to be 12 volts? If so i'm going to look for a bad wire before I buy a crank sensor. Anybody know how to test the crank sensor?
Today I replaced the ECM, crank sensor and the coil packs... still no
spark. A Snap-On diagnosis computer isn't recieving a tach signal. But the
harmonic balancer and crankshaft pos. sensor are new...? Unless they are
way out of wack they should be working. And their not that I can see. I
have power at the crank sensor, and all the wires ohm out to be closed but
not to ground.
Doing a scratch test I can get spark.
Somebody get me a match, i'm going to fix this car once and for all.
any damage to the balancer?? dual ring theres a special tool for this to
check the spacing of the rings on the balancer if its bent you would have
to much or not enough clearance for a signal pick-up?? or damage the
note i'm going by the first posting of a 3.3L engine
