injectors won't fire

This is my problem:
My injectors are brand new accel injectors, I had just put my miniram intake. The car was running good before I took off the miniram. I had to replace the gasket, and after I got it back together the car would just crank but not start. So I checked wiring, the two fuses in the box, replace my ignition module, checked the fuse next to my battery. I think that is everything I did, I don't really know how to check my ecm to see if it is alright or not. Right now I have an ecm on order and am waiting for it. I don't know what else to do, any help from anyone would be great!

thanks
jason

Jason,
If you removed the distributor to install your new intake, it is posible that is out of synch or a 180 DEG out.
Also check if you have reference pulses from your distributor, check your distributor connections.
Good luck,

I don't suspect the injectors aren't firing. Here's an easy way to check. Unplug one of the injector clips and put a test light probe into one of the terminals. Ground the other end of the test light. Turn the engine over. With each revolution the test light should dim a bit. If it does, then the injectors are recieving the right information from the ECM and it's time to check that distributor
