Wont run change efi fuse n relay fuel pump not coming on no fire to connection under back seat to fuel tank whats going on 1990 toyota camry DX standard 4cyclinder efi please help cant figure it out
The fuel pump should run for a second or two when you first turn the key on, but then shuts down to prevent the engine from flooding if the computer does not get a signal from the crank or cam sensors which the computer uses to trigger the ignition system. So no spark no fuel. Check to see if you have a spark in the ignition system.
