I have a 1989 900 turbo 2.0 liter I can not get power to the
fuel pump. I don't even get power to the fuse. I can jump power
from another fuse to power it up but I would rather fix the problem.
Any simple diagrams on how the fuel pump receives it's power. Also
when I jump the fuse it starts and will run but it wont idle well
and burns rich if I disconnect the jumper it idles fine but any
attempt to give it gas it dies. I have checked and replaced the
fuel and power relays and no help any suggestions.
This is a common problem
for the 1989 900. The fuel injection LH computer does not ground
the fuel pump relay due to internal problems. This is the most likely
cause. Try to find a good computer you can try. Don't drive the
car with the fuel pump jumped this can be a hazard.
