I am still chasing down my FI problems. Got a new realy board seems to have solved the fuel pump problem. when I switch the ignition on now I here the FP for a brief moment as I think it supposed to do. I have reconnected the vaccum hoses (dumb ass PO unhooked every hose (IMG:style_emoticons/default/fighting19.gif) ). I am sure the fuel is being delivered to the pressure reg and beyond, still need to measure pressure. Alas I am getting no fuel into the cylinders. Crank it for 15-30 seconds and pull a plug and it is dry. Tried 2 diff FI brains and nothing ( I am pretty sure that the new one should be operational). Sorry this is a long explanation. Tonight I want to check the trigger points. As I understand it they signal the control unit to dispense fuel RIGHT? I am wondering if they are stuck closed or bad or what. I don't know I am just chasing my tail. (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif)
Am I going about this all wrong? Thanks Guys, Todd ps. Thanks Dave Darling the help you gave on my last post helped to diagnose the Relay Board problem real fast. new one is in and working (IMG:style_emoticons/default/clap56.gif) |

Yes, the fuel lines from the fuel pump are High pressure which go to the fuel rails and injectors then go to the fuel pressure regulator which bleeds excess pressure off to the return to the gas tank line.
All fuel lines should be brand new PORSCHE high pressure fuel injector hose. Don't use anything else as it won't be rated for high pressure or the high heat from the engine. That's why crappy FI line cracks and sprays at a high pressure gas onto the hot engine. The result is a burnt up 914, see there are lots of pics of those cars posted here. The VW stuff is not rated either. Please use a the FI fuel line clamps that Porsche used too, they don't pinch the fuel line like the cheap carb fuel clamps do. Geoff |
