Arizona stangers - loan me or sell me your old speed density computer!

Anyone in AZ (east valley) have an old Speed Density computer that works that they can loan me or sell me cheap?

Here's the situation - I have no fuel pressure and no voltage on the lines that carry signals to the fuel system. I am about to convert to MAF, but before I do I want to make sure everything else in the car is in working order. To do that, I need to test my theory that my problem is a blown computer.


Thanks in advance for the help!
