Is the ground wire from the battery terminal to the fender still hooked up? I think mine was coroded a few years ago and it would crank but not start , it could have been the positive going to the fuse/relay pannel on the fender I cant remember. There is also a fuel pump test port in the diagnostic box on the right fender I think it is FP+ if you jump it to the + terminal it should run the fuel pump when the key is in the run position. If the pump does not run it may be the relay? I hope you get it going.
