Still no go!

[kwin]

I posted a few days ago about bringing an old suburban out of long term hibernation.
I could not get it to run without dribbling gas down the throttle body.Turns out the fuel pump was seized and the rubber hose that connected the pump to the sending unit had dissolved.
Replaced the pump and confirmed that it runs and still no go.
I am going to crack the main line and confirm that the pump is pumping , next thing was to to the same at the fuel filter and at the throttle body.
I have made sure the electrical side is all working.

Any other suggestions?

Beginning to run out of ideas.

Thanks
