How to go about checking this PCB

Hi, I have this ignition PCB, it opens a valve but does not ignite. I bought a primitive tester for £7.99 and what I checked was the fuse and the output terminals.

The fuse is ok and output terminals show 0.05 (My Ohm meter goes from 1 to 0 and says 200kO on the selector knob dial). But I can't read anything on the input of the grey little box the output terminals are.

I went to the local phone shop and the person there poked around with the meter and spotted a blown capacitor.

He said he would be happy to swap out any faulty part but also said that he had no means of finding which one was which.

Can I find anything conclusive with a multimeter on the board?

I understand that capacitor appears as an open circuit to the 3V multimeter.

If I wanted to order the capacitor, how would I figure out its specs?

Please could anybody check out the photo?

There is a primitive diagram on the box.
