Saab 9-5 2001 crank no start

Hi there Saab friends.
This is my first post here.
So I hope someone can give me any good advice what to do.

Problem: my Saab 9-5 2.0t 2001 model doesn’t start after staying in the garage for 3-4 weeks.

Symptoms: no response on the rpm tachometer, and the remote lock button on the key doesn’t work.

When I turn on ignition everything seems to be normal, when turning the key to start the starter motor turns like normal but the car doesn’t start.
Randomly it fires up for 2-3 seconds then dies, and when it starts there are still no movement on the tachometer.

Things I have done:

Changed cps sensor with new Bosch original.
Changed the di cassette original v.3.7e made in Sweden Åmål.
Changed to new NGK spark plugs.
Changed fuel pump and filter and check valve.
Confirmed that it is good pressure on the schrader valve on fuel rail.
Changed the maf sensor.
Fully charged and new battery
Checked the earth connections.

I haven’t checked for spark with the plugs out, but most likely there’s no spark since it only fires up for a few seconds very randomly.

What is the correct way to check for spark? Is it to put the spark plugs in the di cassette and hold them to earth while cranking?

So if anyone has any idea what should be the next step just shout out, I would be very grateful for any help.

So sorry. Many of things that I would have suggested, you have already done. The only thing not listed that I thought of is that there is no fuel because someone has siphoned and stolen all of the fuel.

Hi there,
I started wondering that myself, but I know the fuel tank is almost full. I could see that when I changed the fuel pump

New CPS sensor and still no wiggle on the tach when cranking with random occasional ignition.
Good fuel pressure, with lots of swapped and new parts, give your wire harness a very good visual inspection not just the ground points. Be amazed at the kind of damage one mouse can do in one day.

Hello,

A happy day!
The car runs again, solution:
It wasn’t a mouse eating up my wires, but the fault was a slightly bended pin in the big connector on the torpedo wall. I had checked it before, but obviously not good enough.
I carefully bended the pin back again and cleaned the connector with "electronic cleaner"
And then it started and runs just fine.
So note to myself again, check connectors and wires very very god before changing out half of the engine.

Congratulations and good job on the visual inspection.
