What is code 1391 on my 2001 dcdge ram 1500 pu 5.2l

Possible failed fuel pump

They wear mechanically & electrically & work
on & off for months

You could have 10 other issues & not be the fuel pump

Look at Freeze Frame Data when it quits

Have you replaced the transmission or steering column/steering gear?

I would start with the throd body and Mass Air Flow system for build up, do not listen to anyone who tells you that low grade gasoline is ok for you to use, your engine will not perform well on it and will cause a sticky residue on the throd body and MAF sensor. Also it is critical that you keep your truck with a clean air filter and service with oil changes and spark plugs as needed, follow dodge reccomendations, I learned the hard way 1994 Dodge Ram PU 1500 Quad and 2008 Dodge Ram 2500 PU both were the same way, they both had trouble with AC and Radiators as well.

hope this helps

No, its all done by the lifters

On a Dodge a lot of times this light comes on because you are putting gas in the car or truck with it running, have someone with a OBD2 box clear the code and try this, when you open the gas cap with it running it sucks air and sets off the light due to a purge in the system. I hope this helps

Your truck is OBD2 compliant take it to a local auto parts store and have them read the code for you they usually do this as a free service, if it doesn't have a obd2 port then your truck is not a 1996 vehicle.

94,95 are the same 96-99 are the same. the 94-95 models have a 4 pin connector as the 96-99 have a round 12 pin connector. Hope this helps

its the security light

Synchronizer , damaged reverse gear
