Intermittant Fuel Starvation? - Saabnet.com Bulletin Board
1989 900, normal aspirated. Rotor-type pump, replaced in 2011 at generic mechanic shop who reused screen. 196,000 total miles.
Last Saturday, with at least 10 gallons in the tank, the engine died on the parkway. Coasted safely onto the shoulder where I tried restarting. Would start and run for around 3 seconds. Set up flares. Called insurance co's towing service, which turns out not to have pickup privileges on that highway. (Sheesh.) Some 15 minutes later, though, car restarted and ran seemingly normal. Left highway and took local roads the remaining 40 miles home, during which it died several more times. On a hunch, and still 10 miles/30 minutes from home, topped the tank right up. It didn't die after that.
Running tests on pump, I'm seeing normal 43psi pressure with engine off, 36 psi running. Pinching return hose (engine off) quickly raised pressure over 60psi, but I didn't want to press my luck with a 28 year old hose, so I called that quits after a couple seconds without finding out if it would go higher.
Tell me about the filter screen and ejector pump. What's the probability one of them is screwed up, given the symptoms? And, if they are, is it just a question of cleaning them, and if not, are replacement parts available anywhere?
