Re: how do i test injectors?

if you dont have enough $ to get some like these ^^ what i did was hook up the whole fuel system, but i left off the intake manifold and i put little baggies around the fuel injctrs and i cranked the engine. some had fuel and others had no sign of fuel, thats how i knew mine where bad, mine was with a 3.1 v6 engine so we are alike,
