Cranks won't start/A-tap shows low cranking rpms
I've had this problem for ever. I even put in a known good motor thinking that the reluctor ring was the problem. (Same issues) The car will turn over but, will not fire. I've checked spark/fuel (good). Relays and fuses are good. I've bought a new crank sensor and that didn't fix it.
A-tap shows only 145-160rpms during cranking. That has to be a bad thing. Right? So could I have a bad PCM? Or what?
Help

Also, what would be a good meter to get for our cars? I'm going to Radio Shack this afternoon to pick one up.
