1999 Volvo XC70 6 cyl Four Wheel Drive Automatic 193000 miles
5 cylinder 1999 XC70. Cranks, but will not start. B+ to each of the coil packs but weak trigger voltage to each coil. Hence no spark or weak spark at plug.
I changed timing belt and used Volvo cam locking tool to hold twin cams in place. Placed tension on Variable Timing unit to hold it in place during timing belt installation. Timing is "spot-on."
I had to remove and replace the exhaust cam sensor to gain access to cam shaft for locking tool.
Fuel pump cycles when ignition switched is turned to the "start" position.
have the same problem?
