so i couldnt seem to get voltage to the egr solenoid. i supplied 12 volts and ground to the solenoid terminals and it clicks just fine. so while i was checking for voltage on the orange wire with the neg lead from the DMV to bat neg. and the pos lead to the orange wire at the connector i get .8 volts with key on. key off i get no voltage. BUT, when i checked cont. i am getting cont. with about 4.5 ohms at the orange wire and bat ground.
so i figured i have a short to ground somewhere on the orange wire. which also feeds power to injectors, fuel pump, O2 heater relay, egr sol., A/C clutch relay, and is fed by the fuel pump relay. they are all tied together. i started disconnecting sensors and such to track it down. ecu disconnected, O2 sensor disc. all the relays pulled. it was only when i disconnected the fuel pump did the cont. stop. so i installed a new fuel pump, connect the plug and again i get cont. unplug it and it goes away. i find it hard to believe that the new pump has a short in it. it works fine. good fuel pres, and all.
am i wrong to assume i have a shorted power wire? can someone with a renix please check the orange wire at the egr solenoid for voltage and or cont. to bat ground? let me know what you come up with.
this all started after i kept getting low ALFACL numbers with the DRBll tester. FSM says low numbers indicate
high fuel pres.--- (new reg and new pump, all test good.)
dirty air filter---- (new filter)
leaky injectors-----(new injectors)
faulty Ex O2 sensor/circuit---(new O2 sensor, tests good)
faulty Egr valve operation/circuit---( new Egr valve, vacuum system tests good and working properly, solenoid tests good, but can not get voltage to it via connector)
i know i am missing something here. any ideas?
