Hey guys. Had problems starting after my lq4 after it was warmed up. Couldnt figure it out. Switched base timing all around and all.

So the other day I pull into the garage after driving it a while and I noticed the rear pump squirter squirting fuel. Or percolating fuel. Mind you the truck was shut off. The fuel level looks fine. What else should I check? Is the fuel boiling?

Check the clearance on the pump arm to the adjusting bolt. It may be adjusted a little tight. Also check the gaskets on the squirter itself. Just some places to start. Eric L

Also check to make sure the secondary throttle blades arent opened to far making the secondary squirter pump prematurely. Hope this helps, Eric L

also pull the pump diaphram and see if it has a metal check ball or a red rubber "umbrella" in the floatbowl. if its the red rubber, change it. they go bad.
