No Spark ...
Swapped in a new engine in my AP1. Car has no spark with Crank sensor plugged in but will spark if I unplug the sensor. I tried my crank sensor off my old engine and that didn't change anything. Only other thing I can think of is the ECM. Car ran just a couple months ago, find it hard thing believe the ECM randomly failed. How common do the ECM fail, anyone else got no spark from a faulty ECM?

Got crank sensor the right way round ?
got a plug in the wrong place, back of cam cover maybe ? That's me done :blink: |
Cam timing. ECU is fine.
Did you put the top end together on the new engine or was it a complete swap? |
I never checked the cam timing. Engine only has 30k miles. I assumed it was correct. That is something I can cross off, does anyone know what resistance the Crankshaft sensor is supposed to have?
|
You bought a complete running engine, and didn't have to build any of the top end correct?
|
Yes, motor came out of a wrecked s2000 complete. I figured the timing was correct but I guess stranger things have happened. I've double and triple checked everything else. The fact it will spark if I unplug the crank sensor has to mean something just not sure what. No trouble codes, unless I unplug the crank sensor then it throws that code. I'll check the cam timing tonight.

It means the motor is out of time. In this condition, it will only run with the CKP sensor disconnected.
Pop the cover and have a look. Possibly someone did some tct work and disturbed the crank with it removed. |
Thanks for the advice I'll check it tonight and post an update.

|
At DTC I'm assuming both cam triggers should be at 12 o'clock. Is that correct or not necessarily...
