1989 Volvo 240 DL - B230F - Jetronic
Car runs for about 10 seconds and dies (it also dies if gas is pressed - any amount of throttle opening causes it to stall) - trying to resolve the issue

At his point i think it might be the TPS or TPS related issue but I would like to check with the community here before spending $ on a new sensor.
I understand that the TPS should be getting only 5 volts of reference current. Mine seems to be getting 12 volts. (could high reference voltage related to malfunctioning ECU?)

I should add that the timing belt snapped while diving (car ran just fine before that, mind you I did have couple of would-not-start right away incidents and at times it hesitated a bit on acceleration). I have replaced the timing belt, but have not installed any of the accessory belts yet (that should not be a problem at thins point, as the car should run without them just fine (?)

Things, which I did check:
- Timing seems to be ok (All the marks line up and I checked the compression which yields around 160 psi across
- Fuel pump seems to be engaging. (did the fuse jump 4 to 6)
- at his point it looks like TPS
- checked the fault codes which read from the second socket 2-2-3 and from the sixth 2-1-4
