HelloThe Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

The relay is above the fuse box accessed on the drivers side above the drivers feet. The relay is in the third receptacle from the left on top of the block. A relay costa from $17 up. if your handy with a solder iron when you get the relay out pop the cover off with a small screwdriver. get a magnifying glass and check the solder joints. Usually they crack from the heat stress. Just resolder joints if you find one cracked. and you should be ready to go. If no joints are cracked then its time for a new relay. I just replaced one on a 98 ram pickup owner said just replace it. so i did.

check the input and output speed sensors for failure,or of different voltages,and or replace both of them at the same time.
