I have an 88 GTI 16V (CIS-E) that isn't getting fuel to the injectors. It was running before I changed the fuel filter and air filter. Both pumps appear to be fine as all the fuel delivery tests up to the feed line at the air box are within spec. However if you pull an injector and do the crank test with the sensor plate lifted, there is no fuel at the injectors. Also bone cold the car ran once off only the fuel from the cold start injector with no power and it died as soon as it got warm. I have no way to test pressures, but I am starting to suspect either the vacuum control pressure regulator or the dpr. I am thinking that changing the fuel filter might have knocked some crap loose in the fuel line that is now clogging a screen somewhere. Are there filter screens in the fuel distributor or the control pressure regulator that can get clogged? Does the diaphram in the control pressure regulator ever fail (we could see fuel returning to the tank when there was air in the system after the filter was changed)?
Thanks in advance Brian
