My fuel solenoid isn't getting power. When wired, I see 0v. When the wire isn't connected, it reads 5v. It usually starts (rough) with this condition but I've been dead on the road at random times and could not get power at high speeds. Seems like the valve was partially opening? I discovered the issue when installing a lift pump. So I made a direct connection from the battery to the solenoid and all issues are gone. Now i need to find out where this voltage loss is coming from so I don't have to pop the hood for every trip.
Does anyone have wiring diagrams for this? My first check will be on the plug the power source comes from. I don't know which pins to check which are specific to the fuel solenoid. And if no power there, where will I be checking from there? Are there any relays or other connection points to check? Am I looking at straight wire from relay 109 to this solenoid?
I also have a mysterious power consumption of about 0.5amps when the vehicle is off. It's killed one battery and now the new one has become noticeable. I've checked fuses and found only 0.1mv drop across the 25A fuse for the engine components. All others have 0mv reading. it's also difficult to check these things because the door needs to be open the access the fuse box but you're supposed to leave the car alone for 2 hours so it will enter sleep mode? Is the door light not part of this letting it fall asleep part? I did have car audio equipment installed summer of last year. So I'm thinking of taking it to them since I can't recall power loss issues prior to then. And not sure if there's anything they could have done which would be related to my fuel solenoid not getting proper power?
