| Re: How to check for a faulty FPR (Fuel Pressure Regulator) and replace it
The '93/'94 FPR is inside the intake manifold. Remove the top cover. Since it is inside the manifold it is subjected to manifold vacuum, hence no need for a vacuum hose. When you go key on to pressurize the fuel system, DO NOT crank the engine. If it starts, it will run away at WOT and bounce off the rev limiter as it will be unthrottled. |
