Just finished installing fore innovations fuel hat dual pumps on my 04 cobra
Returnless setup with upgraded fpdm and relay with a base tune and it won’t start
I’m not positive I wired the pumps to fpdm correctly
The positive wires I teed into the brown wire w pink stripe
Negative wire from pumps teed into red wire w black stripe
It smells like gas when it cranks but won’t turn over

Those are the correct wires. Did you plug in the FPDM ? Try resetting the rollover switch.

Do you hear the pumps prime with key on?

If you hear the pumps and can smell gas when cranking I'd say your pumps are working correctly. Or at least correctly enough to fire the engine. Pull the plugs and see if they're wet.

You have pressure at the schraider valve on the fuel rail?

When I push the valve no fuel squirts out.. I ordered new injectors hopefully that does it

If you have no fuel at the schrader valve, then it is not the injectors.

Do you have a fuel rail pressure gauge? Are you building pressure? I know you said the pumps prime, How many times have you cycled the key to prime the pumps? You might need to do this a bunch of times to fill the lines, then press the schradar valve to release the air. Then prime some more.

Could also be the FRPS, if it is broken or open, could be pumping fuel into the vacuum system and into your oil.

The other option, drop the tank and check the pumps are installed correctly, socks are installed correctly, not clogged, or not pressing against the bottom of the tank.
