1995 F250 XL ZF5 7.3l PSD. Turns over fine, wait to start light won’t come on, fuse #22 is good, bowl heater unplugged, I think I hear a relay click when key is turned on. It will not start without a sniff of something like a dab of gas on a rag or ether. Once it’s running it sounds healthy but has little to no throttle response and stalls really easy when trying to take off in 1st or reverse. I’m thinking PCM but not sure. Any advice will help. Thanks in advance.
