96 hyundai 1.5 DOHC NO SPARK
If not for the kindness of strangers,,,
I have a 1.5 DOHC that has no spark. I am trying to find the information that will tell me what the readings are supposed to be for the coil and crankshaft sensor and camshaft sensor. I have seen several sites with information on it, but some show a transistor pack and some do not. Is there some place to get this information? I just got the car yesterday. The guy I bought it from just replaced the coil pack and that didn't solve the problem. I have power on the harness to the cam sensor. I have power on the coil. it seems it is not getting the trigger signal to spark. Any ideas? |

Check www.hmaservice.com. You'll need to register for an account, but it's
free. I'd put the betting-man's best odds on the crank sensor. The camshaft sensor won't cause this issue-- the car should still start. |

Re: 96 hyundai 1.5 DOHC NO SPARK
Thank you for the advice. I joined that site and got a lot of good
information. It is lacking on this particular motor though. I have power going into the cam sensor but no signal I think. Is there a way to check the crank sensor without changing it? The book I have does not give the specs for the readings. thank you again. hyundaitech wrote: >Check www.hmaservice.com. You'll need to register for an account, but it's >free.

Re: 96 hyundai 1.5 DOHC NO SPARK
I don't recall whether they give any resistance specs. Typically, the best
way to check a crank (or cam) sensor is to attach a scope to see if you're getting the proper waveform. I don't recall whether the sensor on this vehicle generates a square wave or an ac sine wave. For the square wave variety, you'll need power and ground to the sensor, so be sure to check for those items in that case. The ac variety on the other hand, must simply produce the sine wave. Remember, the vehicle will still start even if the cam sensor is bad. If you have access to an OBD-II scanner, you could check for trouble codes. A code for the crank sensor is the primary hint that you should look there. |

Re: 96 hyundai 1.5 DOHC NO SPARK
I do not have an obd2 scanner. I am trying to find one. I do have an old
oscylliscope. I hooked it up to see what was happening. I am getting a signal out of Crankshaft Position Sensor A when I put the positive lead on the wire and the negative lead on the ground. I do not get the same reading or any reading out of the CPS B. Does this indicate that it is bad? How else can I test it without the car running? What else could cause a no spark condition? I have replaced the coil pack with another one. I just replaced the cam sensor. I have checked all the fusable links. I have power at the coil. I just don't have spark. I would be very grateful for your assistance. Thank you very much. hyundaitech wrote: >I don't recall whether they give any resistance specs.
