buggy will not start

[94Dodge Truggy]

Well, here it is. I have been doing alot of work on the buggy including welding. I recently left the key in the run position for a week while working on it. The batteries still have plenty of charge, but it will not start. I have spark but no power to the fuel pump or fuel pressure. Fuel pump is good. I am thinking that from welding and not disconnecting the battery and having the key in the run position that I have fried the computer . The relay and fuse for the fuel pump are fine. Can I have the computer tested? I have a computer for the same year of truck, but it is for a 318 5 speed and my truck is a 360 auto. The truck is a 1994 dodge ram. Anybody have any knowledge on these trucks? Thanks, scott.
