Hard Starting Neon

it could be a coolant temp sensor... but it could also be weak fuel pressure... has the fuel filter been changed lately? seen as its a 95 it should have an external (normal) style fuel filter... if thats been changed might be worth having the fuel pressure checked cause the fuel pressure regulator could be weak or the fuel pump may be weak

it still could be the coolant temp sensor and it deff still could be the fuel pressure regulator or fuel pump... number one sign for those starting to go bad is hard starting after sitting (cold engine starts)... i've only had to replace the fuel pressue regulators on 4 vehicles for the same exact symptoms you described... i haven't had it on my neon yet but several other vehicles...

I agree with Ghost.
You don't specify how many miles are on the car, when it was last tuned up with new plugs, wires, etc., when/if any sensors have been replaced (mainly the o2 sensors and even then mainly the upper one), what/if any fault codes that may be stored on the PCM (you can do the On-Off key dance to get the two digit codes and go to almost any parts store to get a ODB-II readout for the detailed P codes). The 1995 model was the ONLY Neon model to have an external replaceable fuel filter and as it starts clogging up, it will cause issues.
Depending on when the car was last maintained and how many miles are on the car, you may want to pay for a full tune-up and have the timing belt and tensioner replaced - and if it were me - I would replace the water pump too as it is not that expensive, and when a good pump goes bad, it WILL wreak the timing belt, bend valves, and cause far more damage and cost a whole lot more then just replacing the pump!
I know this from working on MY 1995 car. I was given to me by my friend (had 158K on it) and when it blew the timing belt (either it blew because the water pump seized, or the timing belt warped it when it snapped) the #1 intake and exhaust valves were bent, and all three rocker arms needed replacing too - as the hydrostatic adjusters were torn off.
Spend a little money and keep it going. These are good little cars. Mine is giving me fits right now, but I am going to see it through. Beats the heck out of car payments!

The temperature sensor for a SOHC engine is on the driver side end of the cylinder head, right next to the Camshaft position sensor. You will need to remove the air pipe from the air filter to the throttle body and shift the wiring harness and brake booster hose out of your way. You may even want to go ahead and remove the EGR pipe just to give you plenty of room to get the sensor out.
