Replaced fuel pumps,pressure regulator. Car started and ran in park. under load would stumble & stall.then not re start.
Went to pick apart,as there is an abundance of new bosch parts there from cash from clunkers.
picked 2 of ea fpr,fi relays, iac,knock sensors,power stage & radio suppression and a brand new bosch external fuel pump for <60.00

after reading your site info i had found out the 2 sensors or relays above battery were actually radio & power stage.
All day i worked through swapping parts with no change to starting.ran battery down so i pulled to charge overnight( <1 month old battery) put it in this morning and turned key car fired up stabilized and continued to run!!!! i was dumbfounded.
let thermostat open & shut it off to tighten distributor bolts and battery connections.
would not restart fi relay working pumps on ??

help they will tow my bertone have had since 1990.
