Please tell me whether the fuel pump or the relay or something else is most likely my problem, and how you would go about solving it.
When I try to start my DX (carb), the engine cranks but won't fire.
When I turn the key to the II position, there's a click and the check engine light comes on. There's no second click, however, and the light doesn't go off. (When my car was still running, the lights would go off a second or two after it started.) The pump is silent and no fuel comes out of the tank.
Someone said on another thread (http://www.3geez.com/forum/showpost.php?p=864614&postcount=5) that the second click is supposed to turn the pump off after the rail is pressurized. Since my rail is not pressurized, it makes sense that I don't get the second click, right?
The new fuel pump that I bought appears to be big. The current wires won't fit on it, so I haven't tested whether it works. I don't know how to hardwire the old pump to the battery to test it.
Now my fear is that if the problem turns out not to be the pump (i.e. the new pump doesn't work, either) then I won't know what to do. I'm new to autorepairs and have neither expertise nor equipment to diagnose electrical problems. Thanks.
