BUICK RIVIERA RIM PROBLEM

1996 Buick Riviera • 240,000 miles

Hi,

My 96 cranks over but wont start. The fuel pressure goes up to 55psi then drops quickly after the key is turned off.

Turn key on pump only runs a second or 2 to prime. Pressure should be steady when cranking.

It loses pressure with the key on and still wont start. It primes then drops right after.

Yes that is correct after it primes it drops quickly from 55 to 0 with in a couple seconds so it has no pressure when it is cranking
