First step - check the engine oil to be sure it's filled to the correct level. Next step, check the engine oil pressure switch and pressure sending unit. Also, check the oil warning light, switch, sensor and wiring / connections.

The tank has to drop in order to remove the fuel pump.

Fuel Pump
REMOVAL & INSTALLATION

Prime a starting fluid through the throttle body, if the engine starts, check the fuel system pressure.

The Fuel System Pressure


50-60 PSI (Pounds per Square Inch)Vent the fuel tank vapors by loosening the fuel cap then disconnect the electric fuel pump relay plug, and start the engine . Allow the engine to run until it runs out of fuel and stalls.After spinning the engine over for a period of (3) to(5) seconds, turn off the ignition switch and reconnect the electric fuel pump relay . Install a fuel pressure gauge in the fuel rail test port, and secure the fuel tank cap.With the ignition key in the on position, verify that no leaks are present and utilize the scan tool to energize the fuel pump. This will bring the system to a stabilized fuel pressure that can be visually verified on the gauge.

If the fuel system pressure isn't in the specifications, replace the fuel pump.

For your 2009 Chrysler PT Cruiser 2.4L SFI DOHC 4cyl

Stoplight switch directs current to the stop lights, cruise control, and shift interlock to turn them on or off
When not replaced, stop lights will run continually or not function, potentially causing premature bulb failure, safety issues and/or the transmission will not shift out of park

Try starting in Neutral. Check to make sure you have brake lights when applying the brakes (brake switch could be failed) This is Chryslers listed part number #4659676AC for the neutral safety switch, sometimes called a range switch. It would be listed under transmission sensors.

Easily taken to an auto parts store and have them look at if not sure.

I'm assuming the washer pump is working. The clogged part is from the tiny washer jets. Use the paper clip and try to dislodged the residue.

Probably not the spark plug, probably a bad coil. The spark plug comes out after the coil is unplugged and the retainer bolt removed and the plug comes out with an extension and spark plug socket.

If there is something in the way that does not allow clearance, move it. In many cases it looks impossible to gain enough clearance to remove a coil and boot but it can be done. Remember, most coil boots have some flexibility to increase your angle of exit. Obviously, the firewall can't be moved, but maybe the thing that is interfering is just attached to the firewall and it can move?

Do you do your own repairs and oil changes. My answer will be drastically different depending....
