My '84 88 takes longer to start if it was sitting overnight. It usually takes three tries. Does the gas drain back a ways and it takes longer for the fuel (pump?) to get back up to the carb?

Hmm... It's always been 2 pumps of the gas pedal and 1 crank to start my 85 for the last 9 years unless it sat for more than 2 weeks. See if you have any vacuum leaks, bad egr, and vacuum test your choke controller. your choke butterfly may be sticking or hanging up as well.

if It's a diesel that's a different story. Weak glow plugs maybe.

Are you using the factory fuel filter? It has a anti-drain back function.

But usually the main wells are porous and leak fuel. A little epoxy works here, but requires removel and dissassembly of the carb. I've tried to link a photo of what I'm referring too. If it doesn't work go to my gallery.

Thanks Don71. I just put a new filter in it a few months ago. Picked it up at Advanced. I'll bet it is draining back somehow. I won't worry about it for now. The few extra seconds starting is no big deal. The pics were great.
