Short crank

Post by 836howard » Mon Jan 07, 2019 3:57 pm

I bought a 2005 xc70 with a blown motor. Mechanic replaced motor but cant get it to start it will only roll for half a second if i go from off to roll position. Then stops cranking. I do have an immobilizer message but i dont know why it qould crank at all if it was the immobilizer. Need suggestions thanks

Turn key on, pull the starter motor relay and jump terminals 3 & 5, See if it will do a long crank.

1. Put the relay back in.
2. Get in the car the lock/unlock the door 5 times in a row with the remote.
3. Try to start car.
