I drove my '84 XJ6 to my son's graduation a few weeks ago (it drove ok) and I haven't been able to get it started since. Not a hint of ignition. I swapped out the fuel pump from a parts car I have and tested both. They seem to work ok. I checked spark with the number 6 plug out and had spark. I squirted starting fluid into the spark plug port and got it to sort of fire. Seems like a fuel problem. Any suggestions?
