well first off would like to say hey since I havnet posted in here since I sold the CRX. now down to buisness. just put a b18a1 auto motor into my buddy's 1990 civic SI we have spark, fuel, the timing is dead on, firing order is dead on, and for some odd reason this thing will not crank. The guy before had put a non vtec ZC SOHC in it. I know that for the DOHC ZC you have to change the wiring for the cam angle sensor but is there any thing need to be changed in the wiring for the SOHC ZC swap that we may need to swap back to factory?? we have changed ECU's and still no luck.

 

does not crank????
your battery is dead.

 

no crank....check the starter to see if its engaging

 

got it fixed up injectors were clogged. thanks for the help though
