Hi, guys I just change the spark plugs 2 days ago in the morning. And after that my car won't start it crank only.
I wondering what happen I use volvo oem spark p the same size and number as the last ones. I revised all.the cable and electric connection everything looks fine. I am assuming a coil ignition or cams. Does anyone what could happen.

Thanks,

Is it hitting at all?

You may have blew the fuse to the coil packs. Fuse F34 in the engine compartment. Also check for voltage on the Green-Blue wire to the coil packs ... with the key in POS. II. Grounds on the coil packs, there are three of them on each coil pack, one is the bolt.

If engine turns but no firing change both coils. eBay sells two for $35us, cheap. Volvo is. Probably $100each. Sand negative blue battery terminals both on engine, frame n battery. N sand positive battery terminal n duct tape to prevent zinc battery terminals oxidising.

If still doesnt start, then charge battery.
If still no start, test change alternator. Can take out n bring to shop to test free or just replace for $150.
