Good for you and what a relief. Post 10 explained it exactly. The basics within an hour would have pin pointed were your problem lies. Basically 3 full sides to eliminate as to where your problems lies for any mechanical problems and or running problems, the fuel supply side, the motor side and the drive / prop side.
Always start with a fuel sample for condition of fuel, always run on a known clean fresh fuel supply, test fuel pressures, read spark plugs, compression test, maybe leak down test after that then of course if its a fuel injected computer controlled motor scan it somewhere in that mix. These are the common basics that any tech should have done right up front.
If the gas tank was filled completely 100 % it is possible that the greatest tech in the world could have missed a broken fuel pick up but once the fuel level started to decrease in the gas tank and the running / starting problems came back, he should have known it was the fuel supply where the problem lies.

In the long run, my first bill was around $1300, I think. Plus, this bill for $850 = $2150 Can you believe this for a simple broken fuel pickup hose? The first mechanic said one full pump made the other fuel pump got out. I believe neither pump was broken. They were throwing parts at my engine hoping something would stick.
At least now I am more comfortable working on my engine. Can someone answer this question? Why are the bolts metric v standard? I thought the engines were GM?
Thanks for everyones help.

Old castings used in new packages, results in some unusual bolt configurations. I have some studs that are metric one end and American Standard the other.
Would much prefer 100% one or the other, probably metric if I had to choose.
