Hi Klaus, A thank you for your help and a follow up as to final results of the low fuel lpressure probelem. I ordered another pump and when it came, I took the old unit from the tank.Turned out the pump had worked loose, including the clamp holding the rubber line and slid down a little, allowing some of the gas to spray out within the tank. I just snugged all back up, and the car is running great again, without the new expensive fuel pump! My wife is a happy person, besides I have something off my to-do list. Thanks again!

First off, I want to thank you for your assistance and guidance with this problem. While I restore old Nashes and Ramblers, that technology does not help me much with this Volvo! If I could bounce a couple of ideas, I would appreciate it. This one had the code 2-2-1. I replaced the fuel fitler. Checked for Vac leaks (none.) Went and bought a fuel pressure testing kit and just checked pressure, found 24 psi. manual says we need 43.5. Ah ha! Next I pulled off the P reg return line to make sure nothing was returning to the tank with lower than required pressure. Line was dry. No line leaks anywhere on the pressure side, front to back. Therefore, I am thinking there is nothing else to the system other than the fuel pump. Is that correct? If so, sounds as if I need to get a new pump coming my direction. Anticipating this job, I looked in the manual which says one must drop the gas tank. I guess that means there is no provided service access through the floor (this is a station wagon.) Have you ever had to replace an 850 fuel pump and managed to do it without dropping the tank? Many thanks again for any information you can give. Jim Dworschack http://www.brickboard.com/AWD/?id=1356771&rss=1 Fri, 26 Jun 2009 16:48 GMT Thanks for your reply to my question about the occassional power loss that is getting more frequent. I replaced fuel and air filters, spark plugs have been recently replaced. Upon checking codes I find 2-2-1 that the manual says "long term fuel trim part load, upper limit." I could find no explanation for this or probable causes in the manual, and am wondering if you can shed light on what this means I should look for. Hopefully related, the car often starts with a normal brief cranking, but other times must be cranked over for up to 30 seconds before starting, running badly for a few seconds and then seemingly clearing itself, settle down to normal good running. Thanks for any additional help you can provide! Jim Dworschack http://www.brickboard.com/AWD/?id=1355574&rss=1 Sun, 21 Jun 2009 04:01 GMT I have a 904 850 with auto trans. My wife drives this regularly, and we just rturned from a 600 mile trip in it. It drove perfectly except for the car 'bogging down' climbing some grades near our home. The slow down was much more than normal, the trans downshifted as it should under these load conditions, but even flooring it, the engine just did not respond. Later on, full normal power restored itself. THis problem has happened to my wife about three different times in the last 1500 miles. The engine seems to be firing on all 5 cylinders all the time, even when bogged down. Anyone have any ideas as to what to chase? I recently replaced the fuel pump relay due to a random stalling problem which the new relay seems to have cured. This power loss problem had occurred before relay replacement. Thanks very much for any help.

I firt tried replacement of the fuel pump relay, and that seems to have cured the problem! Many thanks! Jim Dworschack, Wisconsin http://www.brickboard.com/AWD/?id=1353094&rss=1 Tue, 9 Jun 2009 01:49 GMT My backup lights have never worked on our 94 850 wagon with an auto trans. Bulbs work, fuse seems fine, so now I suspect the switch. However, I'm not sure where it is located. Took the console apart around the shift lever and don't think I saw it there. I see a couple of impossible to get to two wire devices deep down in the trans area, and am hoping none of those is the switch... Or is there something more logical to suspect than the switch that I have overlooked? Thanks very much for assistance! This bulletin board is great! Jim Dworschack, Wisconsin http://www.brickboard.com/AWD/?id=1347095&rss=1 Sun, 3 May 2009 04:01 GMT We have a '94 850 wagon with auto trans. Owned it for almost three years, from 105000 to now has 161000 miles. The first couple of years, about 4 times a year, we would be driving along and the car would simply quit as if one turned off the ignition key. You had to sit for about 60 seconds before trying to start it, as it would never immediately restart. This stalling originally happened only in the summer heat, at varying speeds, load conditions, etc, so the problem did not seem dependent on any one event other than a hot day. No codes show for the car. Now the problem is occurring sometimes 3 times in a day, sometimes not for weeks and summer heat is not here for sure! So far it has always immediately restarted after the approximately minute wait and runs perfectly. I have seen other early 850's advertised on ebay with this problem, which leads me to think it might not be unique to our 850. Have other owners experienced this problem and found a solution? The entire ignition system, cap, coil, wires, plugs have been replaced over time (the coil was a used unit tho.) Any and all help would be appreciated!
