Bosch LE Fuel Injection Relay

[David McCollam]

Does anyone know a substitute for the single fuel pump relay for the LE injection? I think mine is shot. There is no "click" when energized on the starter circuit and I do not seem to be getting fuel delivery. The Siemens PN is 90 158 443.

Thanks.

The LE main relay won't "click" just by energizing it as it also has electronic sensor connected to the ignition trigger which must be pulsing for it to energize, i.e. tells it that engine is turning over/running!

Quick easy test for FI E-pump is to jumper air meter electrical plug terminals 36 to 39 at one end of the plug with ignition key on! This works for ANY L or LE FI!!
