ok i finished my head and intake swap wednesday night but a dead batt kept me from playing.

i charged it and cannot get it to fire.

here is what i know.......

* yes i removed and installed the dizzy correctly
* i have spark on the correct cylinder, my daughter cranked it while i shot the timing light and it hits about 0-4
* i have 40 psi at the rail

i removed the spout to kill the advance and still nothing

are the inj pulsing??

mattdel

stick a test light into one of the injector harness plugs and see if its getting pulses.
the neg wire of the light goes to one side, the sharp edge of the test light goes to the other.

Injector has continuos power, the computer pulses the negative. Use a noid. Turn key on check for power. Clip to pos terminal check for neg pulse. Use a noid. You noid enough at it not going vroom? Check to make sure all is plugged in. Box of noids is like $20 and will cover about all vehicles.
