I am currently trying to get my 94 4x4 pickup back on the road and the fuel pump is not kicking on. When i jumped the diagnostic box i can get the fuel pump to work. the EFI relay is currently working and supplying power to the relay under the dash for the fuel pump control. I am currently trying to test the other inputs on that relay however my sources of information/diagrams is very limited. If anyone has a link to the factory wiring diagrams for the fuel system it would be of much help!
