Difficult Cold Start

Problems

Several things could be causing difficult cold starts for your Diesel Pickup:

Problem: Poor fuel quality

Problem: Glow-plug problem

Details

To check the glow plugs:

1. Listen to the glow plug relay. You will hear an audible “click” when the key is turned on.

2. Check all the wiring leading to the glow plugs for breaks or cracks in the insulation. A single chaffed wire can throw out a whole bank of plugs.

3. If the wiring looks good, measure the resistance across the glow plug to see if it within specifications; an “OL” reading on your Digital Multi-Meter means there is no continuity in the circuit, and the glow plug is bad.
