one moment please while I look up diagrams !

This code is for low voltage to the IDM ( injector driver module ). I would start by checking the fuses above the batteries in the battery box . I believe there is usually one for the ECM , one for the IDM and one for the tranny ( if automatic) . A lot of times the fuse is melted , or the terminals in the fuse holder are discoloured and spread from excessive heat and the holder may even be slightly melted . Have a look and get back to me while I chase the diagram further !

I found the problem, a large three wire plug next to the below the wiper motor.

If the fuses are good and the holders are in good shape , then we need to follow the wiring to connector 9260 and connectopr 9261 , which are just a little further down the wiring but still above the batteries and check them to make sure all is well there . If all is good up to there , then we need to check the 3 wire connector 6323 next to them in batt box . If good, then follow the wiring under the truck to check for rubouts and corrosion anywhere down that wiring up to around the starter area . If all is good up to starter area , then follow it up to just above the starter. Let me know what you find from that point.

Oh good! Glad you were able to find the problem ! There is also another connector you might want to check while you are there ! It is also known for bad connections causing the same problems. There is a connector just behind the oneyou just found . It is a square looking 12 pin connector that has large wires and small wires in it and most are purple in color. If you check that one , you may find some more problems in there! Just a heads up ! If you need a picture of connector , I could send you it !
