Its prolly been hotwired. Imagine a racecar on its roof/cage (nah, can't happen). Inertia switch should kill the pump, (but its been hotwired) Engine quits, which should kill the pump, But as long as the ignition switch is hot, it just keeps pumping race fuel, out of wherever the system as cracked open, Over whatever hot or flaming bits happen to be around

On my car, the pump runs when the starter is energized, and when the ignition is on and the flap of the airflow meter is opened. It never runs when the engine is stopped and the key is simply turned to the "on" position. Based on Tess' description, it sounds to me like her pump is running with the starter energized, and then stopping when she releases the key. I don't have a Spider wiring diagram here, but it might be productive to check and see if the pump is powered by two separate, fused circuits; two separate switching circuits to the relay (one from the starter switch, one from the ECU); and how the fuel pump inertial switch is wired in (it could be tripped). I've heard many times that the Spider doesn't use the massflow-based switch to turn on the pump, and instead uses the flywheel sensors. So the sensors could also be a culprit. > > Tess, I'd suggest this test: have a friend connect a 12-volt test light to the power terminals of the fuel pump, then have him/her watch as you crank the engine. The light should come on with cranking and stay on until the engine comes to a stop. If the light comes on with cranking and then goes off as soon as the starter stops, there is a problem in some part of the circuitry that I've mentioned. > > > Rich Wagner > Montrose, CO, USA > '82 GTV6 -- > to be removed from alfa, see http://www.digest.net/bin/digest-subs.cgi > or email "unsubscribe alfa" to [email protected] > -- > to be removed from alfa, see http://www.digest.net/bin/digest-subs.cgi > or email "unsubscribe alfa" to [email protected] -- to be removed from alfa, see http://www.digest.net/bin/digest-subs.cgi or email "unsubscribe alfa" to [email protected] ----------------------------------------------------------- This message contains confidential information intended only for the use of the addressee(s) named above and may contain information that is legally privileged.
