hi i have a set of dsm injectors and i was wondering if there was any way to test them to see if they were any good being i got them from a friend who thought one of them was bad

9V battery, tap dont hold the leads to the injectors connections. If it clicks, it works. Thats not to say its not clogged or anything of the sort, but it will tell you which ones work. You should really get them flow tested when you get a full working set.

Yeah take them in. It's about $15/injector and they'll flow test them as they sit, then clean/fix them, and flow test them again after they've been taken care of. Worth every penny too. Denso makes a good reliable injector, but by the time they come out of those 1G's they are usually high mileage. They get pretty gummed up after all that, so $60 to make them new again is a steal.

^^What he said. Never take a chance with used injectors. Send them in for cleaning/testing. If you send them in, worst case scenario is they are fine and you wasted $60. The other worst case is much worse and much more than $60.
