2000 Acura TL changed the fuel pump car runs good but now the TCS light and check engine light are on.

Make sure one of the wires leading to either back wheel that controls the anti-social brakes wasn't disconnected while taking out/putting in the gas tank.

If it happened right after the oil change, I would take it back there first.
Even if they can't fix it, they need to know about it if you have it fixed somewhere else. They might be on the hook for the repairs.
They could have left something unplugged which would turn on the check engine light. The traction control is affected by the engine performance.

This is strange. The tcs is a traction controll error. If you are getting misfire codes and traction control warnings, then I would have your control module tested to make sure it is not having intermittent power issues to each component.

Check and test injection system. 300 is misfirn random and 306 mifrie cyl #6

this ussually happens if there is a transmission fault yes they are related dosent mean any major problem though could just be a sensor

Sounds like the transmission is starting to slip. If you have an Acura dealer check for fault codes, you will more than likely find a malfunction code for the transmission.

acura 1999 3,2tl .check engine light on ,my computer show code P0141 , 02 HEATER CIRCUIT, [BANK 1, SENSOR 2] please to help find problem .thank you

these lights are not like a check engine light that stays on with a memory code. the only way to turn these lights off is to fix the problem.

Try changing the fuel filter.

you may have a faulty crankshaft position sensor this is what controls the firing of the plugs. you may also have corrosion on the plug for the coil pack causing multiple misfires
