Fuelish problems...

01 Blazer Xtreme 5 speed. Searched on this one and thought I had found the issue...

Truck slowly began to have a hard starting issue. Would crank for a long time. After first start, it was ussually good for the day though. If it sat overnight it was back to hard start. Eventually it got to the point where it just wouldnt start anymore. I replaced - plugs, wires, cap, rotor and coil, all to no avail.

Put a pressure gauge on the test port and it read 52-54 PSI at prime.

Sounded like the notorious bad pump. Replaced that over the weekend, now she makes 61-62 PSI at prime, but still no start.

Injector? Spider? Regulator?

A little history:

I have an 02' Extreme that I picked up recently that was a theft recovery. It had no fuses or relays in the underhood box. I swapped all of them out of this 01' to see if it would run. I purchased a complete box from a wrecked truck and installed it into the 01'. This was in January or so, and the truck did not display any of these hard starting symptoms for a few weeks. Could there be a bad relay that is supposed to fire the injector? Or open the poppet valves? All of the fuses are fine...

Any help would be much appreciated!!!
