Starter died trying to start with dead fuelpump, both are replaced starter switch is good, new starter+pump work. But it still won't get fuel, maybe the fuel sending unit? I keep hearing people suggest the distributor, but it just had a tune-up and ran buetifuly
Large engine model. looking for the fuse but not labeled unless aux
All the time.
It will start but will die quickly! Can't use the lights,heat,or radio
The fluid is leaking out from a part about 5 inches below the reserve opening. I can see it leaking out when the car is running. Even more so when the steering wheel is turned. I go through about a quart every 10 - 20 miles. The part that's leaking looks like a small metal cup with a lid and a screw on top. I'm sorry I don't know my cars, so any educated guess would help. Thank you!

Was able to get it to start the next day and it idled fine but as soon as I put it in gear and tried to drive it died after about 15 feet. Now I am unable to start it again and I don't know whats wrong with it. Help me please
