I've got 30psi in the ring. Timing When everything is wired and working correctly, #1 injector should fire with #4, and #2 with #3. The firing sequence is controlled by the FI trigger points in your distributor. Check to make sure your injectors are wired correctly (see FI wiring diagram in your manual) and that your trigger points are clean. Drag a business card through these points to clean them. Are you sure your FI components are all there and correct for your system. For example, it is pretty common for people to have all kinds of weird problems only to discover later that the wrong ECU was in the car. For your '69, you want the ECU VW part number to end with "B". > reinstalled.

If the repairs were make using crimped connections, the connections won't hold up for long before something vibrates loose or allows corrosion to get in and make the electrical path resistive. Splices should be soldered, and the unions finished off with shrink tubing. -Mark Fuhriman '69 Fastback ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
