knock sensor replaced car won't start 850 1994

I have a 1994 Volvo 850 turbo. The car starts fine when cold, but does not want to start when hot sometimes after few attempts it finally turns and starts. This only happens when the car is warm..

I took to a local garage for computer dig. it show the code 143 which is the knock sensor. To make sure it was the knock sensor I took it to the volvo delear they ran the test and it showed the same code 143. They replace the knock sensor but as soon I got home it did the same...

Any idea?

Please help... thanks
