Need to check the timming on a 98 grand am 2.4L twin cam

Most likely 180 degrees out of ignition timing , check ignition is at No 1 on compression not No 4

Just connect it to the starter hot wire and you are OK

you may want to scan first to get codes.

yes it is quite possible that valves are bent if the cam belt broke or teeth stripped off of old belt, which unfortuneately means removing the cylinder head and getting it repaired (valves replaced and possibly guides) see some of my other posts for cam belt timming marks locations etc...
depending what motor is in your vehicle twin cam or single?

and if its twin cam you usually need cam locking tool for cam gears.

TIMMING IS NOT ADJUSTABLE. IT IS ALL COMPUTER CONTROLED. THE ONLY TIMMING IS THE MARKS ON THE CHAIN AND GEARS.

if its a single cam the marks should be on the backing plate and if it is twin cam the two marks should face each other on the compression stroke of the number 1 cylinder and the same goes for single cams line the mark up with the backing plate in the compression stroke of number 1 cylinder.

If the belt hasn't been changed in a while, it's a good idea to do it while you're in there -- it'll save a lot of labor later -- check owner's manual for belt change interval.

Hi johnsmith992 this engine has a timing chain and has coilpacks and you need not do anything to service these items. regards mark

bring the piston no 1 on the top position check the cam shaft si moving freelyon the outer side of the shaft there are 2 gear with 14mm bolts and 1 extra whole, put a long bolt in the empty space and try to turnthe engine the bolt will go further in the space than the timming is set put the chain on that should do
