Asked by Apr 24, 2017 at 10:16 AM about the 1985 Dodge RAM 150 Short Bed 4WD

Question type: Maintenance & Repair

been trying to update components in the engine compartment since they have never been replaced. Having trouble with getting the engine running. There are three units the left one has a inline white 3 prong plug. One of the other two is the start run but the third is a question also. Dodge couldn't help either. They had a picture but no number.  (1985 100 Custom, w100)

Finally found an engine component chart that also had pictures. They show this as being an EGR time delay

What’s the unit on the left. Mine is leaking any idea


the one on the left is the egr time delay. I didn't replace it. Have taken the pollution pump off and it never made any difference. The problem I finally found on mine was the sending unit in the gas tank was bad and put a new one in and no problems since.
