Fuel Presure Regulator Or Fuel Pump Relay Location

91 LS with a new Fuel Pump and still will not start. It cranks over fine, however, it appears to not be getting any fuel. So, I'm guessing I need to check or replace the Fuel Presure Regulator and/or the Fuel Pump Relay. The fuel pump is working fine.

Any ideas on their location?

Thanks and Happy New Year!

Relay is in the main fuse box in the engine bay, lift the cover and look underneath, sticker will show you which is which I think.

How long have you cranked for? you may need to crank for a 30 second burst, but certainly no more than that or you could overheat the starter windings.

Thanks! I cranked several times for at least 15 to 20 seconds each. I'll try again today for a bit.
