I had a question quite a while ago about this but I havent gotten to work on the car for a while. I get fuel to the pressure regulator but none into the rail or injectors. I have changed the fuel pump, and the regulator with different ones and still no change. It seems like maybe the fuel lines had gotten switched around by the previous owner in an attempt to fix it. Too complicated to explain...... Prior to me doing anything the lines went past the filter into the engine. He said he had the injectors tested and they were clogged completely. I reversed the lines so that it went through the filter first. After that fuel comes out of the return line on the front of the engine. Then I changed the lines going into the rail from under the car to make it take the correct direction and still nothing. Pump-filter-regulator. Does anybody know the exact path that it takes so I can trace it to make sure that I have it all correct. Also i have changed the relays around with others from another car. I really have no idea at this point. I can take the hose off before the regulator and it seems to have more than enought pressure. Any Ideas would be greatly appreciated. I am just frustrated.
