OK, pump started up when I did this. >Check power is reaching the relay on blue/yellow from the ECU relay under >back seat with a voltmeter. Yes, ignition on puts 12 volts on this lead, ditto on the grey one. >Check relay as above (remember to remove ECU grey wire first). Pump >should >run. Do you want me to put 12 volts on the blue/grey terminal? Seems like that is working OK. >If it sounds the same as it has been doing, it sounds as if the ECU has >been damaged. Is that a small relay style box under the back seat? >This "hiss" sound; is it just running, or doing something less happy? Just sounds like the fuel running though the loop. Car runs fine although the idle is a bit low since I moved the carpet off the gas. Here is fun thing, with the ignition off I hooked the voltmeter on the blue/grey terminal and turned on the flashers. The terminal went from 0-12 volts in time with the flashers. So that looks like the fuel pump relay is OK and somewhere else there is an interaction between it and the hazard relay. I tracked the blue/grey lead back to a wee box on the back seat kickplate, beside the heater outlet.
