Google or Bing it. Lots of blogs about disarming or disabling security systems. Is this a factory installed alarm? You will have to pick carefully, but there may be a saab story out there!Prepare for a big learning curve. I'm happily too old to learn, but it looks like a lot of wiring there.

Maybe the anti lock brake ecu is bad or the sensors need to be replaced on the appropriate wheel as indicated by fault codes for the ABS system.

Fault codes were not provided on the original 1989 model of the Saab 9000, but the 1990 to 1991 model ecu can be installed and fault codes read from the AntiLock warning lIght flashing codes.

Check wiring to ensure there are no opens to the module from the ABS Wheel Speed Sensors.

Maybe check that the wheel speed sensor is picking up a sinusoidal wave of AC electricity when the wheel is spun as seen on an oscilloscope function of a multimeter. This would isolate the problem to wiring or the ECU being at fault.

You can tell how to put a jumper across the relay primary by looking at the diagram on the side of the relay. But your problem is probably the fuel pump safety cut off. It is different on different cars, and I don't know where it is on a Saab. But I can tell you some cars use an oil pressure switch for this, and you can tell because it will have more than 1 wire then. Some cars like VW use the alternator, and a bad alternator will do it. Others, like Jaguar, use an inertial switch. It can be behind a kick panel, in the engine compartment, or even in the trunk on Ford.
The idea is you want the fuel pump to cut off in an accident.

engines have a fireing order for each piston like 18436572 for an eight cylinder the distributer cap will have eight spark plug wire connections starting with number one connect plug wire to number one cylinder then moveing clockwise around the capconnect plug wire to the number eight cylinder untill all wires are connected in order to the right cylinder

1 - make sure there is enough oil in the engine to start with - you may just have low oil. 2 - the oil pressure switch could be faulty - any garage will test the switch for you for a small fee, best to know this before embarking on any repairs or remedies.

3- if you found that both of the above are ok then to clean the engineyou can use a proprietary engine flush such as wynns engine flush,

your local motor shop should have a few different types of engine flush. these here are what I would use as have always had good results. "Gunk" is another good buy but a little more expensive. The "flush" is poured in the engine same as oil and mixes with the oil, you run the engine for 5-20 minutes (as per instructions on the tin) at normal temperature and the oil and flush go round the system dissolving all manner of grime and varnish, burnt oil etc, you then drain the engine oil ,let the engine drip with the sump plug out for a good 20 minutes at least to get as much of the oil oil out as possible - if you disconnect the ignition coil (to prevent the engine starting) you can then crank the engine for a few seconds to empty the oil pump of any residual flush and oil. Now remove the old oil filter and fit the new one (take the rubber seal out of the new filter and wet it with fresh engine oil, then put the seal back into the groove on the filer and fit the filter to the engine) then refit the sump plug (with a new washer - auto shop £1 ) , fit the new oil filter and add new oil to the engine upto the FULL mark on the dipstick - start and run the engine - hopefully your low oil pressure condition is gone. If not youre looking at a worn oil pump or a generally worn engine - Low oil pressure in a high mileage engine is nothing to really worry about, but ZERO oil pressure is terminal
Oil for your car is 10w/40 -[part or fully synthetic (fully synthetic is better but more expensive)
The oil pressure switch (if faulty) can be obtained from most auto parts shops and maybe available from saab dealers parts desk (which is best option because you are sure to get the proper official part and not a cheap copy)

You dont. Alternators DO NOT require polarisation as they can only be fitted to vehicles that are wired as NEGATIVE EARTH. If you have replaced the Alt, reconnect the wiring, reconnect the battery - Positive lead first then the negative lead, then start the motor !! Using multimeter, check the charge rate at the battery. It should be around 13.8 volts. The charge rate SHOULD NOT go above 14.7 volts and if it does, turn the motor off immediately and recheck the connections, especially any battery voltage sensing wires. if nothing appears to be wrong, contact an auto electrician and have them check things out. I have known faulty regulators, even in new Alternators..

the valve seals in the motor are worn and letting oil seep into the cylinders when the vehicle sets overnight. when you start it in the morning it burns off the collected oil.. have oil seals replaced if you are parcial to your car....

the clutch is fed by the brake's .. its actuallly jsut break fluid.. if your low on clutch fluid it means you must have a leak check the master it self for leaks.

in the boot behid the tool tray on the right side ther is a cable with a yellow platic thing hanging pull this and your flap will unlock

the metal rod came off the inside. You need to come in from top with a slim jim to open and then work on the door by taking panel off. Get a locksmith or call the local dealer and ask who is there SAAB roadside assistance. Also Cadillac dealers have a roadside service.

You'll find the access panel under the boot floor. There is, or used to be, a large one for the pump & a small one for the gauge sender unit. The pump is held in with a threaded collar.

Common issue on ZF transmissions. Reverse clutch failed and the only way is overhaul/change transmission :(

If the starter is left in the engaged position ( trying to start the engine) the first thing to fail will be the pinion over-ride clutch and then the armature wires melt out and the starter is dead.. If it costs you a new starter motor that will be an expensive lesson for you to fix problems when they occur and not leave it for RON (lat-er -RON)
