The indigo wagon has been cursed with on/off hard starting.
The fuel pump was replaced with the newer style (smaller style) pump in 1998.
I still suspected the internal check valve as a potential culprit, which my
mechanic confirmed with a fuel pressure test.
I sourced a newer style replacement43 mm pump, but forgot to get the
Of course I realized this AFTER pulling the pump from the tank.
The interesting thing is that the 43 mm Pierburg replacement pump currently
in the car uses the old style banjo fittings on the hose, instead of the
hose clamp required by the "new" replacement 43mm pump.
I also could not figure out how to pull the Pierburg pump out of the
adaptor sleeve to install the new replacement pump...
Of course the wiring connection are soldered to the Pierburg
pump....crimping connectors on is easy enough, but it appears that there
are some capacitors solder to the end of the leads...
Any advice, tips appreciated, and yes, I took photos...(of course I can't
send them to the list)
