I'm Awesome
Hi all,
1993 Sierra, 305 TBI, 135K. Truck runs well, but when it's "cold", aka sitting for hours/overnight, if I turn the key, it will start and die. In order for it to actually start and run, I have to crack the throttle just a tad with my foot. Then it starts, and "catches" and runs fine. When truck is slightly warm/operating temp, it will start with no assistance each time, but not when cold. Any ideas? New fuel filter a year (3K miles) ago, fuel pump seems to work just fine when the truck is running.
