993 95 crancking without starting

Hello every one,
I have an issue with 993 1995 with drive block system.
The car was sitting for almost 2 years. We replaced the battery.

Car cranking not starting. Doesn't seems to start
We confirmed spark available, timing is correct.
Fuel pump not starting.
We confirmed signal available from immobiliser to ecu available ( pin 27), pin 18 also have power.
DME relay replaced. First stage power of relay available.
Pulse sensor replaced and gapped correctly to 1 mm.

We noticed only 1.2 v supplied to pulse (crank position sensor) sensor from ECU.
Any body knows How much should be the power. And how to further diagnose the non start issue
