ok so i just bought this car from david great guy. told me all about the 2 very honest. anyway he told me about the car would not do a cold start and that it might just be a sensor. i havent tried it yet i wanna make sure what the problem really is.

ok so the car starts cold but i have to disconnect the coolant air temp snsor. and reconnect it after its started. thats how david told me how to start it. so help me identify these parts cause it might b causing it.


this might b for the MAP or vacuum im not sure

this is prolly for the air intake temp sensor

these might b for cruise control box. im disappointed woner where it is? and i dunno how to diagnose the speedo problem

same thing as above

ok thanks guys

The last 2 look like its for cruise control,. but by the looks of your bay you dont have cruise control. am i correct??

you also mentioned you have a speedo problem,. what exactly is it?

^^ you probally need to replace your rear speedo cable,.. I have posted about it a million times at least, no joke... Its pathetic that still isnt a sticky.... If you want me to I guess I can find the thread AGAIN and give you the link.... I assumed you didnt have cc because i didnt see the boxes in your bay,. but since you do i have no clue what that is for.

IAT sensor wont cause any problem,. mine hasnt been working since i got the car and it hasnt caused a problem yet other than that code always being thrown when i do a diagnostic.... and i highly doubt it could cause my car to have the problems it has now(if you have been reading my threads) lol....

isnt the IAT vital for a cold start? and the check engine light isnt on. only when i take out the coolant sensor to start the engine.

when you unplug the sensor you are putting the car into default. that makes it sends more gas. if that coolant temp sensor is bad the car thinks that it is at temp and dose not use the cold start injector.
