95 Lumina 3.1 won`t start - no spark

[ChryslerCordoba]

Greetings from Finland.
I'm sorry to poor language skills. Problem: 800 km during the crank sensor replaced (3 times) 2 at one time fault in this. Changed to ECM, ignition module, coils. Sparky still missing. How to go about this? The car has worked well (a small twitching, blackouts related to this problem) does not start in the morning. I forgot, fuel pressure 55 Psi. Hopefully I get help. Thank you.

Check for 12v at the pink/red wire at the ignition module, check the wires from the crank sensor to the ign module also, look for a break or chafe in harness, check all the fuses of course.

All checked and ok. Does not work. Also, sensors 12 volts. Ohmmeter sensors also ok. OBD scanner with no defects. 3 misfire.

Today error code 82? "3X refence pulses were not detected by PCM during cranking" or "ignition control (IC) 3X signal error". Which? Or whether the same thing? Now apparently camshaft sensor. Why?? 800 km and 4 sensors??? The worst of my life shopping. Question: Why GM manufactures Chevy? Answer: Opel that would not be the world`s worst car.Now i agree.

Again. Look for harness problems from the ckp to the icm and the pcm. Or the ckp is installed wrong, or the damper is damaged. The cam sensor will not prevent the car from starting it just may crank longer. By the way the reference voltage for the sensors is 5v you stated 12v?

Cables checked and ok. But the crank sensor does not contact the ICM 2 pin (573 and 574). Should there be a direct link crank sensor?

both crank sensors are considered momentary switches in how they operate (hall-effect switch)

24x. connect multimeter to both leads, use continuity function, and it should appear "shorted" . Put a piece of steel between magnet and switch and it will be an "open" circuit.

7x works the same, but in presence of a magnet, will appear "shorted", normally it will appear "open"

you can crank the engine to see if both switch on and off

Fuel press. also too high. should only be 47.5 MAX key on engine off.

Thank you Kevin. You opened my eyes. I knew that the sensors have 2 (one 3100 engine in the back) but I did not read about anymore (3 weeks unnecessary work and 350 € cash). 7x crank sensor is about a nobody. Fault Code 82 "3x cranksaft ..." might bring. More tomorrow when I get a new part if you do not drink ...... . Fuel pressure in a 55??? A big thank you to everyone. Tomorrow.I hope you understand that I wrote.

Now works fine. No more twitching. 7x cranksensor broken. Once again, thank you very much.

was the sensor bad, or the wire burned?

A bad sensor. Wiring condition (hand experimenting). New sensor and not the car I have ever been so good.Starting, perpetrating (no twitch about 1x/5km ).Time will tell.
