2001 Saturn L200 Repair Question
Saturn L200 Fuse Problem
Okay, just got back home and read your post. You haven't given up, that gives me hope! Here goes. I just checked the power at the pump fuse, got power on both sides, key off, as well as while cranking. Not sure how or why, but that is the status at this time. I've swapped the relay several times, I even have an old relay with the plastic cover removed, I can plug it in, squeeze the contact together and energize the pump. Still no fuel guage movement even while doing that. I did get the guage to read half to three quarters (correctly) at one point the other day while trying to pull the relay out. I've opened the fuze box looking for any loose wires, corrosion, nothing apparent. Next I'll check the crank position indicator ohms, as soon as I can locate it.
I think we stumbled on something here sounds like the problem is in the fuse box where the relay is if the fuel gauge poped up while moving the relay around.I would pull the fuse box out and look at the connectors for open terminals you will see the terminal openings going into the fuse box sometimes there are open terminals that have been that way since the car was built.Then one day it starts causing issues try pushing on the fuse box while watching the fuel guage?ALso post some pics of the terminals on the harness side?Also you looked for white corroded terminals on the harness and fuse box side correct?
I opened the fuse box a couple of days ago, right after the pump and fuel gauge came to life. I thought I had found the problem, tried to start the car, and no luck. I tried dozens of times to duplicate the occurrence, but never could. I opened the box, pushed on all the wires to make sure they were going into their respective spots, nothing seemed to be amiss. There wasn't any evidence of corrosion anywhere, but I even squirted an aviation anti corrosion treatment into the sockets just to be sure. I'll open it up again and look closer to see if I missed anything. I even treated any of the grounding points that I was able to see in the engine compartment. I never worked on a Saturn before, so everything about it is unfamiliar to me. Should I still check the crank position indicator ohms? I am still wondering if the security circuit is keeping it from starting. The security light doesn't stay on after turning the key on, it illuminates for a few seconds then goes out. Not really sure if the replacement BCM is doing it's thing, seems to me that something has the ignition shut down. Never did get spark when checking for it the other day.
With no spark fuel gauge etc thats not anti theft that will only disable the fhel.injector pulse.If you were moving around the relay and the gas gauge starting working i would be looking at the fuse box and connectors.Did you look for open terminals on the harness going to the fuse box?
Checked out the box several times, can't see anything suspect. Haven't looked at the connectors on the harness, but I will do that now. I will uncouple them and look at the terminals.
Please post some pics of those connectors.
Not too sure I know how to do that. I will have my son help me with that when he gets home.
I opened the fuse box again, took a photo of the inside, and a photo of the only connector that I could unplug with a bundle of wires that go to the box. (along the firewall) There are connectors inside the box on the left side, but on the outside there are only wrapped bundles of wire, no connectors. There might be connectors inside the top portion of the box, but I can't see how to seperate it from the lower part. I didn't want to break anything prying it apart. Now I've got to try to get the photos out of my camera and onto this website.
I attached photos, two of the fuse box, one of the only connector I could see that goes to the box. Let me know if I am missing something, because I can't find any other connectors.
Well, after much head scratching I finally figured out how to take the "connectors" apart from the top of the fuse box. Duh...when you told me to look at the connectors I really didn't know what you meant, and I looked for connectors in the wiring harness going into the box. I told you that I didn't know how to seperate the top of the box from the bottom, and didn't want to pry on it and possibly break it. It took me a while but I figured it out myself, undolted the plugs and viola! Here are two photos, and everything looks okey to me. Will treat with anti corrosion and put it back together. What next?
PS Adding photos was easier than I thought it would be
