Hard To Start SR20DET

[blacklable245]

Ok so this has been going on for awhile now just havent had the time to look deep into the problem, and before i started anything i wanted to get some ideas of what could be going on.

After letting the car sit for a couple of hours (2+) and try to start it up, it turns over a few times but it doesnt start till i smash on the gas a few times. Also, i have HORRIBLE mpg. I think it is due to a bad O2 from what i have been reading, if thats the case, anyone know where to get a sensor for SRs?:confused:

wow this is like the 5 thread about this

Check your ECU for codes, i can almost gaurentee your ECU will Flash a code 13

Which is your Coolant temp sensor
its either Unpluged or bad
$21 at autozone get it for either the KA or a 94 Sentra SER
the CTS is located above the Thermostat housing you will see two sensors the left one is the CTS when you remove it coolant will flow so be prepared to catch it.
Alfter installing and hooking up the sensor reset the ECU and all should be dandy
