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.
