what happened to the 8 lines? I needed to know what was said!

Re: 96 hyundai 1.5 DOHC NO SPARK
What are Crankshaft Position Sensor A and CPS B? Your car should only have
one crankshaft position sensor.
A quick look at the schematic (ETM tab, fuel section) shows a shielding
wire and two signal wires. If you hook the scope between the two signal
wires you should get an ac signal (similar to a sine wave) when cranking.

Re: 96 hyundai 1.5 DOHC NO SPARK
Well you will not believe this one! I bought another crankshaft position
sensor and it did not solve the problem. I put the new one in and hooked up
the scope just like you said. I tried to turn it over and the stupid thing
started sparking all over the place. I was getting spark but not at the right
times. I tried to turn it over and I could hear it back fire and try to start.
But the signal is somehow coming from my oscilliscope not the sensor.
The crank sensor has three wires on it. One is the one that goes to Crank
Position A and one goes to crank position sensor B. Those two are the ones
doing this. Would the CPU be bad? Is there a power line that could be bad
powering up the CPU?
I also have a power problem with the windshield wipers. The power line that
goes to the motor does not have power. If I jump it to the battery, I get
full function of the wipers. Could these two things be related somewhere in
the power lines?
By the way, I am a licensed Automotive Electrician. I just have not had this
problem before.
By the way, it is a 1.8 not a 1.5.
Well, any more suggestions? I want to thank you for all you have done alreay.
You have helped so much. Thank you. I really mean it.

Re: 96 hyundai 1.5 DOHC NO SPARK
I just found out that this car has been wrecked before. It had front end
dammage. He told me he drove it from California to Michigan after the crash.
It sat for a while and then wouldn't start. Could it be the SRS module under
the center console? I looked. There are no air bags in the car. I didn't
notice that before. Could this be why I have no spark? I am not familure with
the safety cut off that Hyundai uses. Can this be bypassed?

Re: 96 hyundai 1.5 DOHC NO SPARK
Let's back up a little. I assumed you had an accent because you said you
had a 1.5 DOHC. What kind of car are we working on?
The air bag system is in no way related to starting/not starting.
Does the check engine lamp illuminate when you turn the key to the "on"
position? If not, then we need to figure out why the computer isn't
turning on. If you don't have power to the wipers, then you might look at
that circuit first. Could be a common cause. I'd check all the fuses,
even the large slow blow fuses, and especially the one in the small fuse
box on the positive battery cable (if you have one).

The air bag system is in no way related to starting/not starting.
Does the check engine lamp illuminate when you turn the key to the "on"
position? If not, then we need to figure out why the computer isn't
turning on. If you don't have power to the wipers, then you might look at
that circuit first. Could be a common cause. I'd check all the fuses,
even the large slow blow fuses, and especially the one in the small fuse
box on the positive battery cable (if you have one).
had a 1.5 DOHC. What kind of car are we working on?

Re: 96 hyundai 1.5 DOHC NO SPARK
Car 1996 Elauntra 1.8. Car was wrecked and has no airbags. I origionally
thought it had a 1.5 but it is a 1.8.The check engine light is on when the
key is os. I have a signal coming from the crank sensor and from the cam
sensor. I have power at the coil. I have replaced the cam sensor, crank
sensor and coil pack. No spark. I have no idea if the cart has other problems.
I hooked up a scan tool and no codes were set. The only time I had any kind
of spark was when I did what you said and hooked my scope up to the two wires
on the crank sensor. When I did that it tried to start, but the spark was all
wrong. No scope no fire. All fuses have been checked with a meter.If the car
was in an accident, wouldn't the cpu shut off or some other device shut
something off? The guy said he drove the car to Michigan from California
after he had the car repaired from the accident. He said it just wouldn't
start one day. I have tested everything I can think of. Something is keeping
the coil from getting the fire signal or the signal to break the power to
cause the coil to fire. What else could it be? I really am stumped.
Thank you again for your assistance. I hope that Hyundai appreciates what you
are doing for them. I sure do.
