Subject: Help with diagnosis...


This group has been great help to me in the past, and so I hope you can lead me in the right direction. Subject car: 1990 Saab 900 Turbo Convertible, approximately 170,000 miles. The other morning I came out to start my car. I turned the key and it turned over and started for a few engine revolutions and then immediately quit. Subsequent attempts at starting didn't work. Now my guess is that it's something to do with fuel deleivery since it did initially turn over. First suspect for me is the fuel pump (comments?). What is the easiest way to test the fuel pump? Just pull the back seat and listen to it? Pull a fuel line or injector? Additional maybe related information: Over the past months, occasionally the engine would cut out on deceleration kind of acting like the hooter valve was going. The hooter valve was just replaced last year, so it's doubtful that that is what was going on, but it acted much the same way. I am suspicious that it may be related and could also be related to a fuel delivery problem. So I guess what I'm wondring is do fuel pumps go catastrophically and do they show this type of symptom? Or could a hooter valve actually keep the car from starting like what I'm seeing? Thanks in advance for you collective wisdom. -klaus
