    Cold Start MFI Issue

    It takes some time to start my 73E especially in cold weather. It would appear to me I'm not getting the quick early fuel squirt into the stacks. I know my Thermo Time switch is good. Any ideas where to look next ? Thanks in advance.

    Try the easy stuff first like the relay, then manually energize the solenoid with a jumper wire to see if it works, check the fuses on the rear 3 fuse holder, beyond that you need to get out the meter and check circuits. I actually once solved one that turned out to be a bad ground between the breather cover and the case. Loosened the nuts, sprayed carb cleaner around the gasket, tightened it all back up, checked for ground again, and then it all worked. That one did have me scratching my head a lot.
