[76C10Stepside]

I'm back from a long vacation from the S10. The driver side injector went from not spraying to a constant dribble, which flooded the crankcase with gas for the second time. A new injector got it back up and running. Runs pretty well, drove it around yesterday. But there was a slight smell of gas. The first time I looked for leaks, I didn't see any.

New Problems!

1. The coolant temp guage does not register at all.
Cleaned up the ground connections at the front of the intake manifold as suggested, then started engine to see if that fixed, only to find...

2. BOTH of the fuel line fittings in/out of the throttle body were leaking. After tightening both very snug, it is still leaking slightly. I noticed that the line fittings have plastic seals on the ends. Will I have to replace entire lines with new ones?

Thanks
