Fuel Pump: Testing and Inspection

INSPECTION AND REPAIR
If the fuel system is suspected of delivering an improper amount of fuel, it should be inspected and tested in the vehicle, as follows:
1. Make certain that there is fuel in the tank.
2. With the engine running, inspect for leaks at all fuel feed pipe and hose connections from fuel tank to injector. Tighten any loose connections. Inspect all hoses for flattening or kinks which would restrict the flow of fuel.

Fuel pump flow test
1. Test fuel pump by connecting hose from Throttle Body Fuel Injection fuel feed line at the engine to a suitable unbreakable container. Apply battery voltage to the fuel pump relay No. 3 pin.
2. Fuel pump should supply 0.24 liter (1/4 quart) or more in 15 seconds.
3. If flow is below minimum, check for fuel restriction. If there is no restriction, check pump pressure.
