Soild CEL

I have been working on my TPI project all winter and its almost there, but I still have a few bugs with the electrical system I think that either I have a bad prom in my ECU or the whole thing is bad. I did the prom myself and have a Moates adapter. Using Atmel EEprom chips with a Moates Burn 2 and correct software.

Basically when I hit the key, the main fan comes on. And the fuel pump primes. I am getting 5 volts and the B pin of the ALDL connector, but when I ground it there is no change on the CEL, it is just solid. The car is not to the point where it can be started though.
