To all of you expert xc90 techs....I have an 04 xc90 that we replaced the motor in. it is a 2.5 and we replaced with a like motor...same vin digits etc. We have changed motor out...no problems with R and R ...went to start motor and it will crank very well but not fire....what am I missing....any help is much appreciated....thx

 

Just to ad a little more info....the car was running fine before motor change...just had a bad knock in engine. Seems to have no spark now????
