As I was getting on the highway this morning my '93 AAZ just died. It cranks strongly with no weird sounds or smoke.
Towed home where I find that there is no voltage at the fuel cutoff solenoid. If I jump it straight from the battery the solenoid clicks open and
the car starts and runs fine.
Fuse 18 is good, so on to the relay (#104...also listed for glow plugs). To be honest, I'm not really comfortable with how relays work, or wiring diagrams.
Here's the relay.
30 receives 12V when ignition is on.
On the bench, there is resistance between
30 &
85. When I apply voltage to
30 &
85 it clicks...and
87 has 12V out. No other combination has any noticeable effect. As far as I can tell, it seems fine...but I don't really know what I'm talking about, and I still don't get any voltage at the fuel pump
My only conclusion is that it's between the relay and the pump...but it's a straight run from the relay panel to the cutoff solenoid.
Where should I start? I've just pulled the fuse panel down as far as I can and am attempting to figure out which connector I'm dealing with on the back (Bentley is flipped and reversed to my current perspective
)
It's my daily driver so I'd like to figure it out sooner rather than later.
Thanks for any insight.
