was any "crack" sound heard when removing or re-installing spark plugs? also was any oil sprayed into the cylinders during the compression test?
Have a feeling the vehilce was just flooded, especially if the compression test was done without disconnecting the fuel injector harness. If neither of the above (cracked plug or oil) was done, recomend cranking, and cranking with your foot on the accelerator, all the way down until it starts, to clear the cylinders. Will run rough for a few moments, then should be fine.
Let me know.
