Re: 1998 S70 HELP WONT START

Hey Joe, don't really understand what you say you did. Did you check for fuel pressure at the end of the rail near the throttle body? It is possible for the fuel pump to run and not put out pressure. Did you replace the pump? Maybe a line came loose in the tank. Try to start the car then pull the fuel line off the filter and see if any fuel comes out there.

- Jump terminals 15 and 87 on the fuel relay socket.
If fuel pump runs, car should start.

- If not, then check voltage at terminal 15, with key in position II, you should have 12V there.
If not check ignition switch/wiring etc.
