I've been trying to diagnose a no start problem. This is a continuation of the original thread '240 fuel pump, or something else' started on Tues 9/28. So far I've determined that my fuel pump works if I jump fuse box terminals 4 and 6. Obviously, that means I am getting 12 volts at the pump with the fuses jumped. If I take the jumper off and measure the voltage at the pump I'm getting nothing, or close to it, both with the key in the ON position and when cranking. I took the cover off the relay and watched it and it is doing nothing when I turn the key to ON or when I crank it. I resoldered the relay as I read in the archives, and still nothing.
If the car sits for a few hours, it will start and run for a second or two. The first time I tried to restart it after letting it sit over night it ran for about 20 seconds. The longest since then is 2 or maybe 3 seconds.
Assuming the relay is good, what are the other possibilities?
Thanks!
