What brand of fuel pump was used?
Fuel pressure 60/66 lbs?
When it no start check fuel pressure and for good hot blue spark to all plugs.
Any codes or check engine/security lights?
Post back info.

You are welcome and thanks for posting back the fix.
Yes Ac-Delco/Delphi fuel pumps are the best.
If you had a Airtex fuel pump in it That was your problem for sure.:lol2:
