Sounds good ninemil, I would also check for any bent or disconnected fuel lines that would restrict the fuel flow as well. I do not know if this has a fuel pump assembly but you should be able to hear it actuate on when the key is in the "on" position. How did it act before you shut it off? Was it harder to start? Make sure you buy a high quality pump (Carter) many of those cheaper brands will fail trust me.

Check for un-isulated connection on the hot wire lead. It might have been after-market but on mine the connection would short out, blowing a fuse. 1 inch of heat shrink tube fixed the problem.

you are saying it is getting spark, and fuel, right? If it is getting spark, and fuel in to the throttle body, check compression-make sure the Mass Air Flow sensor is plugged in, and double check your spark-you say you replaced all those ignition items, but do not say that you have spark.
