I sent you 2 scanned images of the European and US specifications for the fuel injection system. I am not sure if you got it. When you say "Canadian" edition, does this have a carburator instead of fuel injection? This is the engine number break down Position Values 1 B=gasoline engine ( F is gas engine modied to run on paraffin) 2-3 20 = 2 liter displacement 4 1 - single overhead cam 8 valve 2=double overhead cam 16 valve 5 1=Saab 99 2=Saab 900 6 C=single carb D=fuel injection 202 T=twin carb I=fuel injection S=turbo L=intercooler 7 0=no APC 1=APC 8 exhaust emissions control specs 0=no specs 1=Euro 2=Sweden 3=US 9 A=auto trans M=Manual trans 10 G=1986 model H=1987 model 11-16 Serial number The diagnostic steps for the CI system are as follows - I will also send you the scanned image 1. Check for low voltage, breaks in wires, poor connections, faulty relays - 2. Check fuel pump for proper pressure and volume 3. Check fuel system for leakage, faulty fuel pressure regulator, blockage in return line 4. Check for air leak in induction system 5. Check injection valves for leakage and opening duration 6. Check temperature transmitter (NTC resistor) - not functioning, poor connection, break in wire 7. Electronic control unit - poor contact 8. Auxiliary air valve - leakage, not functioning Number 3 sound like it just might be your problem. If you have the CI system and you did not get the scanned images, let me know and I will send it again. "Christopher A. Nowell" wrote: > It's just a '87 900 Canadian Ed. I'm pretty sure it's 8v.
