Just finished breaking in a new engine with MS2 using a carb. Worked fine, now i've replaced the throttle body and injector fuses but i don't seem to be getting fuel and don't believe the injectors are getting pulsed, although mega tune does show inj. timing and rpm ect. Is there an easy way to check and see if the injectors are indeed squirting? THX

l2t442,
Injectors are supposed to have 12V all the time from the battery. You should be able to check this with a voltmeter on one of the pins of each injector's connectors when the ignition is on. The injectors are fired by
grounding them through MegaSquirt using the other injector pin.
