I have been searching the forums, and it seems every thread dies before the issue is solved. I believe I have a CCRM issue. Car started acting like it had a miss. I pulled the plugs re-gapped and put them back in. Wires are good. Car ran ok for a day, the started acting up again. I noticed that my wideband gauge was going dead lean when it started acting up, and I thought I could hear pinging. Then it would straighten up and run ok for a mile or 2 and start all over again. Car sat and idled you could hear/feel it missing and af was lean. It then blew the fuse for the CCRM. I instantly thought fuel pump, so I took my power probe and put power to the fuel pump and it runs fine. Pump comes on, makes no funny noise and will run as long as I hold power to it. I have checked pin #15 on the ccrm and it has good ground. I can hear the ccrm click when I turn the key on, but shortly after the fuse will pop. Where to go from here? I've always been a fox guy so this is all new to me. Car is a 97 GT full PI conversion. The previous owner did everything to it, so it is kind of a hack job.
