Are you using new parts for the ignition such as cap, rotor, cables and plugs?

The reason I am asking is that if you don't there may be something wrong with the old cap, since you you have spark going to it but not from it. So the cap would be my first suspicion.

I hope you get it running soon,

Dirk

If you are sure that you don't have spark at the plugs but do have spark at the coil it pretty much has to be the distributor cap and/or the rotor.

If you removed the wires from the distributor make real sure that they are reinstalled in the proper order. Both Haynes and the factory service manual have them labeled incorrectly.

The correct order is here:

Volvo 5 cylinder engine firing order

Yes cap rotor wires and plugs i gap all the spark plugs to 25 wires are the same cap and rotors i took all apart again and inspect them all look perfect no cracks or nothing no crack wires

When I took everything apart I number the cap and the wires in order so I don't get it mixed I put them on the order that I had I check the photo that you post and both are the same rotor it's in good condition and also in good condition I bought it like 2 months ago

Check the circular, black metal brackets on the back end of the cams, there is one under the cap and there is a different one under the cam sensor. It is possible to put them on wrong and then you can get no spark.

It's also possible for the electronics inside the rotor to go bad, then you get no spark through the rotor. But sounds more likely related to the engine work, check those brackets.

Okay I'll try to check that apt I got the car to run a few seconds dad died and now I don't have any spark even at the coil or nowhere

No spark from the coil is one possible result of a bad cam sensor. Could be the plate, could be something else. Worth also checking the cam and crank sensor connections.

Ok so i check the little plate that goes at the cam shaft and one of the tapbs at the back its bend so it fits any way at the cam but also i saw that the camshaft sensor locks licke its mising something but i am not sure if its that way

The sensor wheel you are holding has been put on wrong. There should be two tabs sticking up. The tab to the right has been flattened by it being on top of the cam end instead of down in the slot ground on cam end. You might be able to pry that tab up and fit it correctly.
