First off you need a scanner and the 3 shop manual is a must!! I say this because in them they have most of the trouble shoot guides you need! with the scanner you can read the values to see if a component is not in the right value range and may need replacing! Most common problem is the EGR water temp switch and the most common on a OBD1 truck is the ground wires I thing there are 4-6. if there not clean you can get all kinds of weird things happening! Also here is a good site for trucks!
