Fuel pressure fluctuation
My 02 Dodge Ram 1500 with a 3.7 V-6 started
running rough at long idle. Then it died out at idle,
then died out while moving and refused to start.
No codes have been thrown. I replaced fuel
pressure regulator/filter, then throttle positioning
sensor and now Air Intake idle control module. No
changes at all.
Please let me know if you have dealt with same
issues or what your fix it plan would be.
Thank you. Paul
Paul,have you checked the fuel pressure?Sound,s like your fuel pump is bad.
