haha...well i checked my coolant and its fine. the only work ive done to my car recently really was install a short ram intake and change my oil? i still need to check my spark plugs and the vaccum hoses.
today when i started my car i had to fight it to keep it running just by giving it gas until it was warmed up...but once it got a little warmed up it ran fine.
Alright, I just might have your answer.
You have an 87 LX-i. So, when you turn the ignition key, you hear the engine slowly cranking and cranking and cranking....until finally it fires up.
First of all, make sure you oil level is at the proper level. Trust me, I know. Next, your ignition coil is the culprit. The ignition coil has a little relay that is connected to ground (I believe on the passenger side fender). Take that relay off and thoroughly clean the connection with some sandpaper making sure that the contact betweent metals is clean. Make sure the single ignition wire going from the ignition coil to the distributor is within proper Ohms specs and is making good contact.
How many miles do you have on your car? Does it smoke when you start it up in the morning sometimes?
Try this and let me know if it works.
You might have answered your own question. You are getting a code for the coolant sensor. This sensor has nothing to do with the temp gage or the fans. It lets the ecu know that the engine is cold or hot so it can adjust the fuel mixture.
Check it, make sure that it is connected. With the key on, disconnect the sensor plug. You should have 5 volts between the 2 wires. If there is voltage change the coolant sensor and see how it starts.
there you go!
and that little relay looks like a small black box just hanging out in the middle of nowhere by itself.
also, when you test for ohms, you always want to be as close to 0.00 as possible (DC ohms). the lower the ohms, the lower the resistance, the better the flow of power.

Mac is right coolant temp. sensor car wont start well when cold since it cant judge the motor temp.
Its loacated on the thermostat housing. It s not the same sensor that makes your guage work.
I'm not even gonna try and explain how to use an ohm meter Ill let google do that.

where is it exactly and what does it look like? gonna try this out tomorrow.
Top radiator hose follow it back to the engine. That housing its clamped to has the thermostat inside its bolted to the head. The plug on it has 2 wires/pins its sticking straight up it will poke your eye out. Resistance should be between 200-400 ohms measured on the sensor.Thats car warmed up. It should be about 50 ohms cold by this chart. I think the wire has plastic coil wrap on them. The temp sensor for your guage has one wire its right next to it.
