I have a 1985 380se, rebuilt fuel dist. new fuel filter fuel accumulator in line reg. rebuilt warmup reg. when injector is removed will not spray fuel unless sensor plate is deprested and the fuel doesn't misterfys only shoots out (fire hose ) since the fuel dist. been rebuilt do I have to change the shims in regulator? can you let me know if pump is activated if injectors should be spraying without sensor plate depresed. thanks.

Does the engine start & run??? What is the problem?? Does the system have at least 75-80psi fuel pressure?

If the fuel pump is running no fuel is injected until the plate is "sucked" down by engine vacuum....

Fuel pressure is 70 psi at pump, 3 at distubuter. when tee is shut off is70 psi. car doesnot run it try's to and so i think the cold start inj. is why .but now no start. the distubuter is rebuilt and wondering is shims need to be changed in pressure reg. in dist. how far does sensor plate travel down before injectors spray. If pinch return line will shoot up to 100. it has differant readings at differant times when testing. thanks
