    Or just plug them into the car? It takes like 30 seconds to get the rail off, injectors are not meant to just be given constant voltage, they are meant for PWM from the PCM... Just put them in the car

    ^^^this^^^

    I was going to mention to make sure when checking them to only give voltage momentarily. Prolonged voltage could cause major problems ; )

    There is a nice write up on rebuilding injectors on here too... Iirc it covers testing too.
