So I have a 94 3.0 5speed that I just picked up. The guy I got it from said the fuel pump was bad. Instead of just throwing a fuel pump at it I decided to do my own diagnostics on it. When I got it home I had to charge the battery to get it to crank. It wouldn't start. I put a fuel filter on it and I got it to start. It runs rough has no throttle response and sounds like its working too hard to keep 4000-4500rpm. No vacuum leaks or fuel leaks. I have seen on the tech page fuel pressure should be between 30-40psi. I have checked fuel pressure and after 4 key cycles tops out at 25psi. Compression looks good too. I just want to make sure that I am on the right track in sayin that the fuel pump is bad.
