Hey guys, I know, there were so many threads, about no spark in LH2.4 swap. But i did't found same problem as mine. I'm swapping 240 with 2.3NA LH2.4. I've got little problem. On connectors for coil, I've got 12v, until I connect them to coil. After that, there are 0v... I don't know what is wrong, 2 coils checked, and 3 Ignition Modules... There are 12v from car, blue cable. But there is nothing from ignition module...

 

the ignition module 'grounds' the 1 terminal of the coil to induce current, then ungrounds it to fire the spark.

you won't ever see a spark if the CPS (crank position sensor) isn't working. you swapped in the EZK ICU as well as the LH2.4 ECU ? the CPS goes to the ICU first, which times the spark and switches the ignitio module, and also sends a timing signal to the ECU which controls the injection.

 

Yes, I swapped whole harness, with both computers, and FP relay. I don't understand why coil "eats" all voltage... Is there a way to check this CPS?

 

the blue wire to pin 15 should be hot if the ignition is on.

when the engine is turning over, pin 1 of the coil should be pulsing high-low


the CPS is behind the head, stuck into the flywheel cover, reading notches in the flexiplate or flywheel as the engine turns. its a pretty simple device, just a coil and magnet that picks up magnetic reluctance. not sure how you'd best test it, it has a 3 pin connector, one pin is ground for the shielding, and the signal is between the other two pins (differential). said other two pins should be around 160 ohms when its disconnected... https://www.volvoclub.org.uk/faq/Eng...stition_Sensor

 

Ye, 15 is hot everytime.
Okay, so everything is saying that both crank sensors what I have, are broken... IS there a way to simulate CPS?
