I have a nifty problem with my 86 XJ6 that even seasoned mechanics can?t get. The problem started with the MAF and I have replaced it with a new one. The car will now not start and run. Here comes the fun. If I remove the relay which I think is the "start" relay.....nothing, won?t start. If I remove the "run" relay the car will start and run with difficulty. If I plug the run relay back in it kills the car. Now yes I reversed the relays and the same thing happens. With the MAF door open I test the fuel pump voltage (with the run relay in place) and have a good 12 volts. By the way the pump puts out 37psi. now, I tried replacing the ecu also but to no avail. Ok now, like I said I got the car to run with only one relay in place but the fun is about to begin. With the car running (poorly, richly, and delicately) I quickly and I mean quickly changed the relays by replacing the run relay and removing the start relay and the car sounded great for all of 1 second and died. Hmmm. I just don?t Know. Any thoughts at this point would be of great help. One "mechanic" told me to keep replacing parts and It will eventually work. Sure, thats the ticket. Anyway, Thanks, Mike
