hi this engine is not in a datsun but in a 180sx many people have experience with these motors so i thought i would ask.

any way i have a problem where the coil pack dont give spark ( i have tried several coil pack to no avail) WHat i cant figure out is that wire connecting to the coil packs have 11.7 volts after testing it with a multimeter but no spark and spark plug.

Also i removed the CAS and turned it by hand the injectors click so thats working but no spark is given (i have tried my spare CAS still no go)

I have gone over all the wiring many times and tried different ground points for the coil pack ground but i just cannot get a spark.

and yes i have tested my spark plugs on my datsun and it gives a big fat blue spark


Any ideas? ECU fault maybe?

o yer i tried reading the ecu fault codes it only i thing i read the codes wrong because from my reading it says fuel pump but the cylinder fill up with fuel and also oxy sensor which would only effect certain rpm running in closed loop right????

Thanks
