Jumped time most likely. remove the oil filler cap and observe the valve train as the car is cranked. are the valves moving?

    He's said the valves moving because that's what's chattering its will start but won't stay started unless he holds throttle down the motor is shakes while trying to start when he lets go of throttle it shuts down he'd just trying to find narrow it down and check all possibilities someone said cam shaft broke in 2 it's a 1999 Pontiac gran prix Se does it sound like it has jumped time

SOURCE: 2004 1.8l nissan sentra what now? not battery or fuel pump/filter

Check your catalytic converter. If you are over 80k miles, these devices will wear in stages. The first stage of wear is slower gear change at cruising speeds when approaching any type of incline. Second stage is the engine light will reveal a faulty oxygen sensor. Because the converter is basically a "filter" built into the exhaust system, it wears by slowly clogging, which leads to no starts, no power, and sometimes a blown head gasket. If your mechanic removed the oxygen sensor before the converter, theres a strong chance it would start right up.

SOURCE: Shuts off will driving, especially if I hit a bumpy road.

It could be the computer. Computers can diagose whats wrong in your car but it cannot diagnose itself. Get a jeep mechanic to check. The computer might of gotten water in it. In a 1996 jeep grand cherokee the computer is right over the right wheel when you looking straight from a seat. The wheel may have slung water or mud up into the computer.

yea you have no fuel and sound like a bad harness and the gm's are know for there fuel pump harness's! did you change it when you changed the pump? there is a lose connection somewhere in the fuel delivery system and it's pretty simply! i would check the fuel pump relay on the left hand side of the engine compartment and maybe even put power to the pump at the relay position "b" on the fuel pump relay harness and there should be a one pin connector to put power to also connected to the same position on the relay "b" the wire should be tan and white! good luck

After checking/adjusting all tire's pressure (including spare, some spares have a tire pressure sending unit), turn ignition "ON" (NOT "START", just the position key is at when you are driving).
Press the MODE button until LOW TIRE PRESSURE HOLD SET TO RESET is displayed.
Press and hold the SET button until a chime sounds and TIRE PRESSURE RESET is displayed and a chime sounds 3 times.
Release the SET button and TIRE PRESSURE NORMAL is displayed.

I had a constant grinding coming from front passenger tire. Replaced Caliper and put the worn pads back on for a day, the constant grinding went away. It would still grind while braking,hitting a bump

It sounds like the brake pads are metal to metal, when you turn the flexing of the wheel makes them touch the rotor and grind. This can rarely be caused by a badly worn wheel bearing as well, have both brakes and wheel bearing inspected.

I have a 2007 ford explorer sport trac had it serviced they checked tire pressure and now low pressure light wont go off. All tires have same pressure

Are all the tires the max pressure? They should be. If nothing else, inflate to correct pressure then disconnect the negative battery cable for 10 minutes and put it back on.

A bytton in my car an when i push it the letters trac on

the button is for a feature call low traction , when the low trac light is on ( on the dashboard ) the traction control system is off. when you press the button again the light should go off ( low trac. on) I leave mine on all the time. it works with the antilock brake system. if the computer detects that the wheels are starting to slip or slide , it cycles abs on and off quickly to help you remain in control of car, feature is more designed for driving on icey roads. Just leave low trac. on and dont worry about it ( no trac, light on dash) hope this helps S.R. Peace
