help with codes

my 95 died on me a few weeks ago and won't start.During cranking,it huffs a bit from intake(a soft popping).Fuel in cannister but no pressure to rails.Could it be cps?My tach does bounce when cranking.Fuses are good and batteries crank over good.i don't have much pressure at bleeder valve on side.i pulled up three codes......P0562(possibly an old code from running down battery), P1661 and P0603.Anybody have any ideas?I hope it's the cps and not the pcm(expensive i think)

Put a fuel pressure gauge on the schrader valve. You should have a minimum of 40 psi. It could be the fuel pump going out.

P0603, is pcm error, P1661 is Output CKT circuit low, P0562 system low voltage. I recommend you clear the codes and then check your batteries.

If it is your pcm, and you have to get a new one go to DP Tuner. DP-Tuner

p0603 can be set by a dead/disconnected battery, or also as a side effect of using a download tuner.
