Disconnect the fuel line from the intake manifold and lower it into a vessel with a capacity of approximately 5 liters.
Remove the fuel pump relay. The relay is located in the relay box on the left rear in the engine compartment.
Motronic injection system:connect with a short wire terminal 30 on the relay socket and terminal 87V and start the pump for one minute.
Multec injection system: connect terminals 30 and 87 in the same way.
The pump capacity should be 0.8-1.2 l/min. The 115 hp engine has production since September 1989, the productivity should be equal to 2 l / min.
If the performance is too low, replace the fuel filter and retest. If performance remains low, replace the pump.
