I've had a thread going on the Yahoo TurboEsprit site but figured everyone needs to share the love. Here's what I'm up against now. Little did I know when I originally posted about poor cold weather running that I'd find this:
Got love previous owners, NOT
I started a post called “Cold Running Problem HCi” but under the current circumstances, I must rename the fun I am having. Thanks to all that tried to help.
After checking out most everything I could with y’alls help I came to the conclusion that something just wasn’t right, nothing associated with the RPM Relay worked. Well obviously the fuel pumps worked but that’s it.
I remembered something the PO owner had told me to be careful leaving the key on because the fuel pumps would continue working. I was even able to do all my cold pressure checks without ever starting the car. Didn’t really think much about that until yesterday. Earlier, somewhere in a post I read that the fuel pumps don’t start working until you start cranking the car but mine did.
Armed with this info, I looked closer at the RPM Relay and was shocked or relieved at what I’ve found. A previous owner in his infinite wisdom to install the MSD CDI box to replace a possibly bad ignition amplifier had wired the RPM Relay totally out of the loop. Fuel pumps not working? No problem I’ll cut the wire to the RPM Relay (87b) and wire it to a wire that previously had gone from the coil to the ignition switch. Another wire, from neg coil, that had previously supplied power when cranking and running to RPM relay to trip the relay found life powering the tach through the MSD.
My car was also missing the Ignition Solenoid, Overboost switch and most of the vacuum lines. Why it even ran amazes me. Brilliant!
Anyway, I’m happy with what I’ve found but a little nervous that once I get this all straightened out that I’ll find the real problem. I’ll keep you informed.
Thanks
