I have my 99 pickup in the shop with 6 burned out glow plugs. 5 weeks ago I replaced all 8 plus relays and wire looms. Apparently the glow plugs stay on full for 2 whole minutes which in turn causes them to burn out quickely. Another computer from a properly working truck was installed and the problem persisted. The books says that there is a cycling device in the circuit as well as a temperature sensing device and a barometeric pressure sensor.where are these located?? My book indicates they are there but does not note where they are located. Please help
