HI, The switch is likely bad. You can buy a new one for the dealer for a lot of $$ or look on ebay, amazon, or a local wrecking/salvage/use auto parts yard for a replacement. Google how to replace the switch. Many Dodge vehicles had poor switch quality in the '90s-early 00s. GL, TD

Battery flat or cables loose, fuel not reaching engine possibly due to a clogged hose or filter, TDC Sensor fault.

Does it turn over? Have you checked the battery?

Diagnose the cylinder misfires Google your codes & study obd 2 vehicle systems TYPE: PO300

The cooling fan is not working check fuse then relay but before you replace parts you must check with fuse tester if there is power and ground to fan motor if not move on to fuse then relay if everything seems ok check ground output from pcm to relay if no ground replace pcm

there should be a code to help in diagnoses. check for voltage at the coil and the ground circuit as the PCM controls the coils.

It means there is at least one transmission code set in the TCM's memory. P0700 is an informational code only. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module http://www.obd-codes.com/p0700

try it on with the sound very low. If it causes no problems that way I would guess it is the output circuitry. HOWEVER, for that to affect the electrical system without blowing the fuse someone must have put a penny in the fuseholder.

P0108 (M) MAP Sensor Voltage Too High, P0118 (M) ECT Sensor Voltage Too High Engine coolant temperture sensor input above the maximum acceptable voltage, P0123 (M) Throttle Positon Sensor Voltage High Throttle position sensor input above the maximum acceptable voltage range, P0522 Oil Pressure Sensor Low Oil pressure sensor input below acceptable voltage. Sounds like you have an electrical problem, either computer failure or bad sensors. It's hard to believe that you gained so many sensors just from replacing the cylinder head. Disconnect your battery for one minute, then reconnect. Try driving it down the road.

Depends what is wrong with it

Fuel not flowing to the engine. I had a Cutlass (for a week) that would shut down for no apparent reason. After being towed 4x, I told the garage to drop the gas tank and flush it out, since I thought it might be bad gas that the previous owner could have purchased. When I returned, they showed me a handful of small tinfoil balls that were floating in the tank. Whenever I accelerated, the tinfoil balls were sucked into the screen that protected the gas line from foreign objects being sucked into the engine. I knew it was fuel related but, I had to convince the mechanics. I'm sure you don't have tinfoil in your gas but, you may have a clogged fuel filter if you bought gas when the tanks at the gas station were almost empty. I'm betting your problem is fuel related, in some way. Find a mechanic you can trust. Good luck, John!

Most of the time if you smell gas in the car .is because a gas line is leaking I wouldn't keep driving the car get it look at as soon as possible .

the alternator may not be charging and so when extra components are turned on the battery has to give out more power instead of the alternator working ,taking power away from the ignition system

replace the cam shaft sensor.located on right side top corner of engine under PCVvalve hoses. she should fire right up,after new sensor installed
