I have a 1995 Saab 900 V6 that is hard to crank when I turn off the ignition. (I installed a 1996 engine the car). The engine turns over rapidly and evenually starts. The exhaust has rich smell like it trying to flood. I have replaced the fuel pressure regulator, the engine computer, spark plugs, fuel pump and fuel check valves with no success. I need help. JR
Sounds like an ignition problem..
The Direct Ignition module in the turbo model can fail but is
easily
tested and replaced.
Remove turn the , Direct Ignition module put the spark plugs in the holes, ground each
plug to the negative battery terminal by use of a wire about 2 feet
long and stripped at each plug. Crank over the engine
over watching the spark plugs. If there is a problem with the cassette, one
of the plugs will have no spark or a very weak spark. Also, when you
turn the ignition key off there should be a shower of sparks that runs all of the plugs simultaneously several times.
DANGER BE CAREFUL ! ! ! EXTREMELY HIGH
VOLTAGE! There have been occasions when the Direct Ignition module would test ok
when turned upside down but would fail when turned back over to install
into the valve cover ?
Also: Oil leakage from the individual coils of the Direct Ignition module have also been a problem. Oil leaks can be identified by
noting that there is oil surrounding spark plug hole.
Hope this helps.
Cheers MMP

I have a V6 engine and it does not have a direct cassette ignition. Thanks for trying,
