Well this may be the "Belts Slipping" you may hopefully just need them tightened? In any event you need to get your transmission looked at by a professional, take it in, and ask for a "Quote"as to this, and go from there.

may have to change the power steering pump.

It sounds like you have a fuel problem. You should replace the fuel filter before trying anything else, and when you do, dump the old one into a CLEAN container and look for water. Dirt should be taken care of by the new filter. If you do have water, you will see beads in the container. Get some isopropyl alcohol or gas line antifreeze from your automotive dealer.

• Code 542 indicates one of the following conditions:

Engine Starts:

· Fuel Pump secondary circuit shorted to power

· Fuel pump relay contacts always closed

· Open in fuel pump monitor (FPM) circuit between ECU and connection to POWER TO PUMP circuit

· Heated Exhaust Gas Oxygen (HEGO) sensor shorted to power

· faulty ECU

Engine Does Not Start:

· Open inertia switch or inertia switch circuit

· Open in or between ECU and fuel pump (This includes open in fuel pump brushes/windings)

· faulty ground connection at fuel pump

The easiest way to check this circuit is to go to the fuel pump relay. If the relay clicks when the key is turned to the "RUN" position, then the inertia switch circuit is ok.

The Pink/Black wire starts from the fuel pump relay and goes two directions. One side goes back to the fuel pump. The other side is the fuel pump monitor circuit and goes to pin #8 at the ECU. This wire should only be hot for a second or two when the ignition is turned to the RUN position.

The fuel pump relay receives power on the Black/yellow wire. It comes from a fusible link at the power distribution center. This wire should be hot at all times.

If all the above is working as designed, them you probably have a bad fuel pump.

Start from the basics,does it have sprark does it have fuel pressure?

Absolutely; Automatic transmissions will slip for a number of factors but the the #1 cause is low fluid level closely followed by very old and brown fluid. Recomended fluid is MerconDexronII. Best of luck.

DASH HAS A SHORT CIRCUIT.DASH NEED REPLACING BUT CHECK FOR SHORTS IN THE WIRES TO DASH.DONT PUT A LARGER AMP FUSE IN A CIRCUIT TO KEEP FROM BLOWING FUSE BECAUSE IF FUSE DONT BLOW WIRES GET HOT IN THE CIRCUIT THAT HAS A SHORT IN IT AND CAUSE A CAR FIRE.

make sure hoses going into the intake are on properly and very tight

Hi:
Normal operation of the headlight circuit is to just have one set of headlights on a time, bright or dim, but not both.

Plug for connecting the Code Reader is located under the dash beside the steering column.

Sounds like the relay located in the trunk behind the driver side carpet panel is sticking on. Contacts are burnt and causing fuel pump to keep running. Tap relay with a screwdriver handle and if it starts, replace the relay.

Check your vaccum lines . Check you vaccum line going in your master brake cylinder.

Take out altenator and take to autozone and have them check it for free, if bad replace it, most altenators have voltage regulator built into altenator
