SOURCE: truck would not start, installed fuel

You may want to check your wires. I would also recommend to check for 6-12V w/ DIGITAL multimeter@ TPL and Idling sensor, right under intake manifold. If you have questions let me know I don't have the schematics for the connector w/me right know, but can e-mail them to you if you still have the problem. I had a similar problem as well.
