problems when turning right or stopping

[thebachelor412]

Once again im having problems with my 2001 jgc. About two weeks ago my car started acting up. It does not want to start until the 10 time i try cranking. When it turn on its starts sputtering and idles real low. Once driving it feels like if if needs gas, when i floor it its drops the rpm til almost zero. After a while it gets back to normal idling that is until i start drivin and turn right or stop real hard and just dies off on me. Then to restart is a huge pain. i have to leave it alone for about 10 minutes. i replaced my fuel pump and nothing i changed my cam sensor and nothing what else could it possibly be??? i thought it could be my ignition coil but i doubt it since that shouldnt affect my car when i turn right. please help guys!!

Did you check the voltage at the fuel pump before you replaced it? You may have an electrical problem. Check the relay, and if that's not it, then check the fuel pressure at the fuel rail to see if it's low. You can get a fuel pressure gauge at a regular auto parts store usually. My 93 JGC was at 42 lbs. If it's low, replace your fuel filter (if it's accessible on the 2001s) and see if that fixes it. If you have sufficient fuel pressure, check the air filter to make sure it's not clogged. If that's not it, then it almost certainly would be an electrical problem. As far as it only doing it when you stop hard or turn right, that's really awkward. If your fuel pressure is low and you have an I6 engine - turning right would push the engine in the opposite direction as the fuel rail and possibly reduce the fuel flow - but that's pretty far reaching I would think. Good Luck

i just replaced my fuel filter and bought a new k&n air fliter. i checked my fuel pressure and it was real low at about 25 psi. thats why i changed my fuel pump thinkin it was that. but nothing.. what kind of electrical problem could it be?

I would look at your pressure regulator. It will affect your pressure greatly. Also, might try running compressed air throughthe lines (disconnected) might have some crud in the lines blocking the fuel flow.

Did you check the voltage at the fuel pump? Verify it's 12 Volts. If you've already replaced the pump, checked the voltage, and you are getting some pressure, then it's quite likely the filter or the pressure regulator.

Sounds like idle air control

A long shot: Try some fuel dryer/anti-freeze. Perhaps some water vapor built up in your fuel tank over time (condensing over cold nights). Just a thought.
