96 bravada cranking but no start

[jhymel]

everything points to fuel pump but i want to get some more opinions before i drain my tank (filled up the day before problem started, so its got to be fuel pump haha).

my 96 bravada wont start. it cranks all day but wont fire off. i know spark is good cuz i if i pour a little fuel in throttle body it will fire off and run. fuel pressure on schrader valve is reading 45lbs. changed the filter which was horrible clogged (could barely blow through it). and pressure did not change

im thinkin of maybe a voltage problem because once the engine is running it works well. maybe there is an electrical connection problem at the pump and when the starter draws all that crankin power, there isnt enough voltage for the pump to pump the needed 54lbs for the poppet valves to "poppet" off. haha.

help...stuck...please...

Grey wire should show battery voltage at the fuel pump connector and less than 5 ohms resistance to ground on the black wire. Key on, engine off, fuel pump running, fuel pressure must be 60psi to 66psi. Must remain above 55psi for 3 to 5 minutes after the pump shuts off.

I agree with OM, looks like the fuel pump to me too.
Get the Delco fuel pump for best results.
