Why does my Saab 900 start and stall?
What could be causing the stubborn starting, stumbling and dying upon startup, etc. is a lack of fuel pressure. When the engine is at rest some residual fuel pressure should be retained in the system. If fuel pressure leaks off then what happens is that the pump is having to purge air out of the system, or burping the baby I guess you could say.
Is the fuel pump on the bottom of the Saab 900?
For what it’s worth, I did find an ’89 SAAB 900 n/a fuel pump and after checking eeuroparts.com, it appears that’s on the same compatibility list as my 900. It looks like it’s complete, except for possibly a fitting that’s on the bottom of the assembly.
What is the AMM on a Saab 900?
The AMM is the Air Mass Meter, also known as the Air Flow Meter, the unit that snaps on between the air filter and the intake manifold. The fuel for any CIS system is controled by the position of a rod inside the fuel control head.
Where is the pressure control valve on a Saab?
If not, the valve should be replaced. The valve has three hose connections. Turbo compressor, which is the source of air pressure, waste gate actuator, which is operated by the air pressure, and the air intake which is used to bleed off air above base boost. The valve is normally open from the compressor to the waste gate, and closed to the intake.
What kind of issues does a 1989 Saab 900 have?
About a month ago I bought an ’89 SAAB 900 that had hard starting and stalling issues. To help clarify things, I’ll describe those issues. First, the hard starting. To start the car, it would require several cranking sessions of about 5 seconds or longer to turn over. Then, the stalling.
How often do you change the oil on a Saab 900 Turbo?
Oil-change intervals went up from 6000 miles to 10,000 on late versions, although many prefer to do it every 3-5000 miles; it blackens quickly due to the turbo’s high operating temperatures. It is wise, especially on non-intercooled cars, to let the engine tick over before shutting down.

What kind of fuel line does Saab use?
In the picture at left, the stock 4-mm rubber hose is was replaced by a 4.8-mm reinforced fuel line. It is less likely to clog, and lasts longer. The check valve (PCV valve) needs periodic replacement.
