May still have a fuel pressure issue. What size engine is this? Should do a fuel pressure bleed down test that would check the spider injection system. Fuel pressure should be up between 56 to 63 lbs at the Schrader Valve on the intake manifold.
Did that the shop replaced flue pump its a 5.7 he had it running but said i had a bad injector so we pulled spider did a good cleaning with carb cleaner and seafome re instaled and now wont start
I suspect the spider assembly needs replacing. The older ones tend to leak, and for best results the spider assembly should be replaced if bad. Do a fuel bleed down test by hooking up a fuel pressure gauge to the Schrader Valve on top of the intake manifold. Cycle the key on/off until fuel pressure builds up and then with the key off, watch the fuel pressure gauge. The pressure should not drop more than 5 lbs in 3 minutes. If it does, then replace the spider injection assembly as a hole unit. They are re-designed from original.
