You have to push in on the back of the seat as in the picture below. It really takes two people, one to push in and one to pull up on the head rest. http://www.matthewsvolvosite.com/forums/download/file.php?id=1748&mode=view

Pull the radio fuse for at least 30 seconds and then plug it back in and see what that does

you may want to check the fuel pump relay. this is a common problem

sounds like you have a computer glitch. i would take it to any auto shop and pay 50 bucks so they can take a look at your e.c.u. (engine control unit) we had a similar problem a few years ago with our 1990 volvo 740 gle 2.3l station wagon. it was a glitch with the computer. got a mixed signal with the mass air flow sensor.

I hope you've solved the problem by now, but there are alignment marks on the crank shaft (top pulley), idler (lower side), and cam shaft (smaller, bottom pulley) which should be aligned with stationary marks on the timing belt rear cover.

The belt has marks that align with the aforementioned marks (lines). The double marks on the belt align with the camshaft marks and the single marks with the others.

Loosen the tensioner clamp (nut) to allow the spring loaded tensioner to press on the belt and retighten the nut.

Rotate the crank shaft (clockwise, probably two revolutions) and make sure the pulley marks realign to the marks on the cover (they don't have to realign with the marks on the belt).

Rotate the crank shaft a full revolution once the belt is on and check that alignment is preserved.

Periodically loosen and retension the tensioner nut (access through a hole in the cover) to ensure that tension is maintained as the belt relaxes.
