drivers side rear under the fuel rail

I suspect the drain is blocked. I would clear the drain vent to stop it overflowing.

Hello. What 'category' did your Saab fail? Was it 'functional' or 'visual' check/test? Good luck and keep me informed; if you want to.

B207 doesn´t have a camshaft sensor

If the key has not been coded with the new ECU the electronics will not release the key. Everything, Saab/Volvo is coded to the ECU.

rescan for a correct trouble code --try boosting battery or have load tested - running out of gas may have overheated fuelpump try starting with starter fluid

Yes it does. There are many causes from poor fuel grade to timing issues. I would take it to a SAAB garage for service.

Remove the rear seats, remove the plastic cover on the lower part of the opening, remove the galvanised steel cover and lift it up from the front and under you will see a plastic hydraulic tank with a brass nut/screw, remove the brass nut screw and fill to the line with a good fluid, I used Lucas hydraulic (power steering) fluid which also has a stop leak (for seals only will not stop leaks in fittings) in it. Utube has a few videos on this opperation and thats where I go to Saab school.

While there are a variety of reasons your Saab 9-3 is overheating, the most common 3 are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.

If this is a tuning box for your vehicles ECU get an expert to fit it because if you get it wrong it will cost you a stupidly huge amount of money to put right. THE GOLDEN RULE! Leave engine tuning to the experts!

Two ways 1. Use the Key. 2. Get underneath the engine. Find the starter motor. Put the positive lead of a battery charger on the positive lead of the starter and the negative to any earthed part of the engine or body. Wait 5 minutes and open as normal. https://www.google.com/search?q=1995+Saab+900+starter+location ..

I suggest you begin by servicing the engine including checking spark plugs, spark power and testing the injectors, fuel pressures, delivery volume, etc., with a thorough visual inspection of pipes, wires and connections. Once done, erase the codes and go for a drive and see what codes come back. If any comes back it will be time to begin serious fault finding... https://www.troublecodes.net/pcodes/p0202/ https://www.obd-codes.com/p0204 https://www.obd-codes.com/p0201 https://www.obd-codes.com/p0246 https://www.obd-codes.com/p0300

Use google for a method.

It would be nice to know what the hose looked like. Maybe it is a heater hose. https://www.eeuroparts.com/Parts/33434/Heater-Hose-Inlet-12798534/ https://www.onlymanuals.com/saab/9_3/2000_06_saab_9_3_4_cylinders_23l_mfi_turbo_dohc_32581403 https://drive.google.com/file/d/1undKbsox0GJVSTLnuM5iLDmu62zgIPQ0/view https://www.youtube.com/watch?v=zRkRPX0AXas https://www.google.com/search?q=2002+saab+9-3+vacuum+hose+diagram&client=firefox-b-1-d&sa=X&tbm=isch&source=iu&ictx=1&fir=-o43GqCWuqTWpM%252C5NTLHP-q3o4P7M%252C_&vet=1&usg=AI4_-kTJ3R3JJ3CFTb_7Tk0UQ-CD5vrHzQ&ved=2ahUKEwit0sncj-TqAhVaHM0KHbI6D0MQ9QEwAHoECAsQFg&biw=1025&bih=520#imgrc=-o43GqCWuqTWpM Pretty safe to bet it is not the lower radiator hose.

What engine ? could have come with two different one's Starter Replacement (4.2L Engine) Starter Replacement (5.3L Engine)

most like ly the clutch actuator or electronic setting from the TCM have a fault code reading done to determine the fault

the ecm has a different ignition code for every vehicle get your keys reprogrammed to the new ecm and the problem is gone

The key decoder at the bottom of the ignition lock cylinder needs to be checked and probably replaced.

Problem is probably the key recognition module below the ignition switch. You will need the service manual to fix this.
