Crank no start, getting spark not fuel
Hey, just picked up a 98 civic lx. It cranks but doesn't start. I am getting spark but no fuel. I was told it has a new fuel pump and I watched him put a new relay in so I know those should be fine. Should I test the fuel pump myself or could there be another issue?
Thanks!
Thanks!

Turn the key on but don't crank. The check engine light should come on then go out after 2 seconds. During the time the light is on, the fuel pump should run, you can hear it under the back seat or outside the car. If the pump runs, disconnect the return hose which goes from the fuel pressure regulator to a metal line on the firewall. Disconnect the firewall end and point the hose into a container. Turn key on again and see that fuel comes out.

Re: Crank no start, getting spark not fuel
Have you checked all the ECU fuses and the fuel pump fuse?
CEL bulb may be burnt out or removed-- you need to fix that, since having a working CEL is important to detect and diagnose problems.
Do you hear the relay click off 2 seconds after turning the key on? A lot of relays will click on when you first turn the key, but the one that cuts off if the engine is not started would be the fuel pump one.
If relay does click and fuses are good, next step would be to remove the back seat bottom cushion and check for voltage at the fuel pump wires.
