    Question 95 Seville SLS cold start problem with instant fuel pressure drop.

    I have a 95 Seville that has cold start problems. Changed FPR, did full tune-up, checked for leaking or plugged injectors, and new TPS. When i hook up the pressure gauge to the fuel rail and turn the key on i get a 20 psi spike than it drops to zero quick. Any one have any ideas????????
