Truck runs like a piece of sh*t. I replaced injectors with g&b rebuilt from Glendale Auto Supplier Southfield MI. I had to send back half of them defective. I got new g&bs from Auto Zone to replace the defective ones Glendale ran out of rebuilt. Fuel still leaking down, $800 so far and still counting, not coming out the f/p regulator vacuum port anyway. Maybe fuel pump check valve?. Kind of cold 2/16/14 in mi. to do a pump on the ground.
