I bought a 1990 Iroc 2 yrs. ago and haven't had much time to work on it. I could get it to crank at first (but only with ether). once it cranked it wold lope while idling, and sometimes it would idle smoothly. when I gave it about 1/4 throttle it would rev just fine but anymore throttle and it would bog down and try to quit. which points me in the direction its starving for fuel. and now it wont even run off of anything but ether. so for some reason fuel isn't getting to the cylinders. it has a new fuel pump and has the right fuel pressure for the tpi. I'm thinking for some reason my injectors aren't spraying. does anyone else have any other suggestions or know what would cause the injectors not to spray?

 

couldnt hurt to change the fuel filter, if havent already.
