1999 9-5 wont start

Goldjason · 10-06-2011, 11:07 AM

Hello Folks,
Hope some folks out there can help me.
Car will not start. Since I do not have any schematics am taking wild guess only.

1) Engine will fire if i inject starting fluid into the intake manifold. This confirms ignition circuit is OK.
2) Crank position sensor replaced
3) Fuse #19 fuel pump circuit checks OK with 12v
4) Can hear pump running when ignition switched on.
5) tried jumping #87 and #30 on fuel relay , fuel pump runs, car still wont start
6) fuel rail on top of engine indicates fuel. Did not check fuel pressure yet.
Did I miss anything ? I am stumped. Hope someone can give me a clue.

Fuel - After you crank the car, look for the fuel valve, looks like a giant tire valve on the fuel rail. If you take the cap off, and momentarily press the valve, do you get gas (Note: you are testing for live fuel, put a rag underneath and be careful).

Autozone has a fuel pressure tester for <$40 with coupon, it attaches directly to the fuel rail and gives you fuel pressure reading. Note: It too will spray gas, ask me how I know

Spark - Look at the black DIC aka DI, is the connector on the end? There are four bolts, pull it off and if a buddy has another one, test with it. Look at the DIC, is it cracked, burned, etc? Harvey's Autohaus has a great demo of T7 systems in the 9-3 forums, there is a test to see if you have spark.

Codes: Is the check engine light on? Can you get a code reader and report back the codes, note most code readers can show the codes, it takes an internet search or special tool to check Saab specific codes.

Air: Check the MAF, Mass Air Flow Sensor, and other air related sensors.

Yes , there is fuel on the fuel rail.d Pump is working by shorting #30 and #87 on the fuel relay.
Swapped with a known good DIC. Still will not start
Yes, it does fire momentarily when I squirt starter fluid on the intake. This means ignition is good ?.
Is there a way to check whether the immobilizer has been activated to prevent starting ? Thanks in advance

Immobilizer is not crank condition

You are not getting fuel its seems have you chacke pressure you need at least 30 psi at the rail to charge the injectors Check fuel pressure, oh you were told that already

Do you have a Check Engine Light on at all? Limp Home Mode can prevent the car from starting as we;;. Happened to me when my Throttle Body was bad and triggering LHM every so often. If I started the car with the gas pedal half depressed it would crank and start right away. Sent the TB to BBA Re-manufacturing and have had no troubles since.

Here is a (kinda bad) video that shows how to check and reset LHM.

Hello Saab Gurus,
I did checked the fuel pressure. It was 35 PSI. I suspect this darn thing is associated with the alarm system shutting off the fuel supply.
Also the luggage compartment release on the driver's side door will not function.
Also I cannot open the luggage compartment manually with the key.
Is there a way to open the luggage compartment manually ?. I do see a mechanical release for the fuel cap but not for the luggage compartment
when I crawl inside from the rear seat to seach for any kind of release mechanism.

Is there a way to completely disable the alarm system. It is causing too much problem for all it is worth from what I have read from the posts. Damn the GM designers ! The "Saab" brand has been permanently damaged as far as I am concerned.

Cranking the engine did produce an error code of P1460. The Immobilizer did kick in immobilizing the car. Looks like it needs to be unlocked with the Tech 2 tool. Unless there is another alternative, must have it reprogrammed by a dealer. Someone did say when they disconect the alarm module, (not just pulling the fuses or relay) the car may start up.
Any one care to confirm this before I start trying it ? Thanks
