Customer Question
05 Topkick. Glow plugs...

05 Topkick. Glow plugs come on for a split second only . Not long enough to warm engine even in moderate temp. Changed the relay , glow plugs are new. Unhooked the temp sensor. Nothing.

Mechanic's Assistant: What is the complete model and serial number of your machine?

Mechanic's Assistant: Are you fixing this yourself? What have you tried so far?

3 different shops have taken a try at it

Mechanic's Assistant: Anything else you want the equipment mechanic to know before I connect you?

It's like the computer thinks it is warm outside. If you plug the vehicle in it starts immediately
