cold start problems
hi guys the car is a jdm s4.
i recently did a tune up of the car and for whatever reason the car does not receive the proper amount of fuel to start. if i squirt starting fluid through the intake the car will start. if the car is already warm and i try to start it, it starts no problem. any suggestions as to what the problem might be? the spark plugs, fuel filter, fuel injectors, intake tubing were all replaced at the same time along with the water pump and install of an e fan.

well you did a bunch of work so you need to go over your basics again, and another time after that. Recheck the firing order, and try adjusting the TPS but turn that screw ever so slightly
sometimes shops and people unfamiliar with the engine turn the TPS screw thinking its the idle

car idles on its own fine, but idle varies slightly from 500 to 700 rpms. rob: I appreciate your input and will make sure to double check my work.
to everyone: thanks for your advice guys! will try to work on the car tomorrow.

i checked the water thermo sensor and the green plug is connected (the one with the plug that looks the same as the fuel injector plug). how would i verify the condition of the water thermo sensor? I'm debating whether or not it's the wiring harness or the actual sensor...

i took a radioshack tap to the water thermoswitch and when the sensor triggers it turns on the fan, its operated using a relay. I'll takea picture this weekend when i get a chance but I'll give it a shot again. iirc i took off the tap but it still had problems but I'll try again
