Hello all, i got stuck in my 930 project.
The car is a 1987 SC Turbo ROW
I rebuild the engine and now it comes to the final start after some years of restoring this car.
Weeks ago I installed the engine in the car and try to start, but without success.
The following steps I renewed or troubleshooted since:
- new fuel tank (after 3 years, the old fuel was weak and rusty)
- new fuel-pumps with the identical original specs
- new fuel-accumulator and filter-cartridge
- measured the flow rate, the system, control and residential pressure (all in specs)
- checked the injectors (some spray ok, some not)
- new fuel injectors
- fuel-head rebuild (iron cast version) with new gasket rebuild-kit
-- tested the fuel outlets (4 outlets delivers fuel with ok pressure, 2 send nothing)
-- double checked the rebuild and figured out an error with a wrong inserted
fuel-cylinder
- fuel-head rebuild #2 (correct the cylinder-position to the correct ports
-- checked the outlets with running fuel pumps (all 6 ports are wet, but no pressure)
-- used that time less loctite 574 because there was to much inside the 1st time
-- all adjustable ports reinstalled and with 6 1/2 rotations installed and precise
measured
- fuel-head rebuild #3 (new gasket kit, all in a clean room with more focus/time)
-- checked the outlets with running fuel pumps (all 6 ports are wet, no pressure)
-- same behavior like the 2nd attempt
Now I canīt believe that the fuel distributor could be the problem...
I bridged the WUR but no symptoms of more pressure. The shims under the pressure-valve in the fuel-head are tested with 2 shims and without...same behavior.
Did any of you had an impulse for me for further investigation.
Iīm lost
Thanks for your help
AJ
