Could very well be the glowplug controller. Its the little black box on the drivers side, rear top of engine, next to the fuel lines.

Also, could be a broken/frayed connection to one of the glowplugs. They are located in the same spot as a spark plug would be on a gasser. Check all the wired to the GPs, and also check the metal bar connecting them together.

BE VERY CAREFUL if you have to mess with the nuts on the ends of the GPs, or if you have to replace any of them. They can EASILY break off in the head. YOu have to soak them with PBBlaster and be very very careful when servicing.

Got this from another site:
Quote:
You can go to the tip of each glow plug individually with a test light connected to 12volts, or pull the right and left outer most plugs on the glow plug module and test each circuit white wires are driver side and red wires are pass side. this is for california spec truck, You will have to check at each glow plug for 49 stater.
Also:
Quote:
Fed trucks it's usually the controller.
Cal trucks it's usually a glowplug (or 2,3...etc)
Here's the procedure from Alldata:

I hope you can read it. I cant get it to zoom out.

Customer Reimbursement - For US

All customer requests for reimbursement for previous repairs for the special coverage condition will be handled by the Customer Assistance Center, not by dealers.
A General Motors Customer Reimbursement Procedure and Claim Form is included with the customer letter.
Important: Refer to the GM Service Policies and Procedures Manual, section 6.1.12, for specific procedures regarding customer reimbursement and the form.
If the work was done by someone other than a GM dealership, the amount of reimbursement will be limited to the amount that the repair would have cost GM to have it completed by a GM dealership.
Courtesy Transportation

The General Motors Courtesy Transportation program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranty. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product program is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. GM dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.
February 2008Dear General Motors Customer:

This will cause illumination of the Malfunction Indicator Light (MIL). Depending on the ambient cold start conditions and the number of glow plugs failing open, some customers may also comment about hard starting, misfiring and white smoking after cold start.
Do not take your vehicle to your General Motors dealer as a result of this letter unless you believe that your vehicle has the condition as described above.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
