Re: Formula 89 TPI 5.7 problem

1. With car NOT running, remove electrical connector from each fuel injector. Using a Volt/Ohm meter set to Ohms, check the electrical resistance of each injector. Each should be 15 to 17 Ohms. Replace any that are not. If you smell fuel locate the source. One or more may be leaking from the seal or the body of the injector. If all is good reconnect the electrical connectors to the injectors.

2.Remove vacuum line from the fuel pressure regulator. Connect a fuel pressure gauge to the schrader valve on the fuel rail. Start the car. The fuel pressure gauge should read about 42 pounds per square inch or metric equivalent.

Report back with your results.
