I'll try to supply as much information i can. Hopefully someone can give me some advice.
Nissan CA18DET running Microtech LT9c and x4 ignition pack
Took car for a spin around the block a few weeks ago, all good. Came out a week later and she just cranks and cranks with no barely a fire.
- On the laptop it's showing 0 RPM on cranking - odd??
- Pulled out CAS, ignition on spun CAS by hand and the injectors are firing.
- disconnected injectors to isolate them. Spun up again and can hear coil packs firing.
- removed my power connectors from both fuel relays in the boot as to not flood the motor. Spun again and can hear the fuel pump relays switching from the ecu trigger.
- disconnected all coil packs individually and used an inline spark tester between coil and plugs. All packs are showing excellent spark so they are getting signal from ECU and are in good condition.
Left injectors unplugged and pumps disconnected as well as coil wiring harness off. Replaced CAS back into the engine and i get NO RPM on cranking?? WTF.
I really don't get it. If the CAS is out of the motor its doing everything it should. As soon as i reinstall its not sending RPM signal to ECU??
any help or tips would be greatly appreciated..
