No fuel @TBI No power @ fuel pump
Cougar replied to ea82blues's topic in Old Gen.: 80's GL/DL/XT/Loyales...
I think the relay is up above the fuse panel area or above the steering column possibly. The problem may be with the relay or possibly the control unit. You may be swap the relay with another one in the car once you find it. -
If you don't have a digital meter that will handle a 10 amp current draw this may be a good time to invest in one. You can get one for around 50 dollars and then have a very valuable test tool on hand when you need it. You can then set the meter in the current function and place it in series with the battery ground connection. Normal current draw should be less than 80 milliamps. By pulling fuses one at a time you will find which circuit has the draw on it and narrow down the area to check for the trouble.

Skip, Not much more I can add to the good suggestions already given. I assume you cranked the engine enough to get gas pumped to the engine in case the fuel in the line flowed back to the the tank. I also assume you have your scope or analog meter to check the injector pulses. In answer to question 2 in your first post, the two areas are seperated from each other. Pin 27 of the ECU has brn/blk wire going to the fuel gauge. Then a blue wire ties between the gauge and the sensor. You should have voltage there. A red/blk wire ties in the ground side to the sensor.

Code 11 is a crank angle sensor or circuit code. The sensor is in the distributor. If the engine runs then the fault may be with the ECU causing a false code. Code 13 is for a cam sensor or circuit. I assume this is related to the same sensor. The EA 82 engine only has one engine angle sensor, that I am aware of at least.

Fusible link replacement 92 Loyale
Cougar replied to Frank B's topic in Old Gen.: 80's GL/DL/XT/Loyales...
I agree GD, 15 seconds is a long time but it does say that in the manual. -
If the motor works ok when you tie 12 volts to it then another thing to check is the blower relay.

Fusible link replacement 92 Loyale
Cougar replied to Frank B's topic in Old Gen.: 80's GL/DL/XT/Loyales...
You are correct about the melting characteristics Frank. They are more like a delay or slow blow fuse. Here is what my FSM manual states about the red colored link. The gauge size is 0.85mm2 and should have less than a 60mV voltage drop across it when a 10 amp current flows through it at room temperature. The fusible link should melt within 15 seconds at a current flow of 130 amps. I would leave the other original links in there though you could purchase some newer style ones for backup. The green is 80 amps and the black is 190 amps. Like GD said, these links should never have to be replaced if things work like they should. -
I assume you are talking about the infamous fuse #12, which ties to more places than any other fuse. One place is the seatbelt switch so check that area out. I suggest you get a service manual for the car to help you with this trouble and since the circuit ties to so many things.

The problem is most likely due to an intermittent power connection, not a short. Looking at some data for your car it shows that in the power panel under the hood, fuse SBF-3 ties to fuse #25 and together they feed power to the areas you mention plus others. A blu/red wire ties to fuse #25 and supplies power to those areas. One of the modules is the security module so perhaps that explains why you can't start the car when this happens. I suggest you check that wire using a test light probe or meter and look for an intermittent power connection. Tapping on things around the fuse panel with a screwdriver handle, while watching the test light, may lead you to where the trouble is.

HELP-My Dash gauges aren't working - 87 Subaru GL
Cougar replied to jroosa030's topic in Old Gen.: 80's GL/DL/XT/Loyales...
Check the fuses and make sure they are all good. If they are good then you might try pulling the cluster panel and reconnect the connectors to the panel. -
After reading through the posts again I think you might have a faulty ECU. I suggest you try replacing that to see if it will get you going.

I believe ECS stands for 'Electronic Control System'. If the light is turning on then something needs to be checked possibly in the drive train system or engine.

Another success story! Glad you got it fixed and thanks for the feedback. You are welcome for the help. Drive on.
