How much fuel pressure do you have.

While the engine is on #1, you can check both #1 valves, the intake on #2 and the exhaust valve on #4. Now turn the engine over 360 degrees and check the valves on #3 and the intake on #4, and the exhaust on #2. > > When the key is turned ON the fuel pump relay and main relay are supposed to > click at the same time, the fuel pump is supposed to whir for ~1 sec and then > the fuel pump relay is supposed to click again.

How is the #19 wire from the control unit to the pump relay. If it is grounded, the pump will run all the time. The connection from this wire of the FI harness to the main harness to the front is located just left of center on the front firewall of the engine compartment. By firewall, I mean the verticle portion of the body in the front of the engine bay. It is a single connector. -- Russ Wolfe '71 FB AT '66 FB MT '64 T34 (not running) '65 T1 (not running) russw@classicvw.org http://www.classicvw.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
