95:ka24de hard to start when car is cold.

[R_G]

When the car sits for a couple of hours it's hard to start. The car cranks and cranks for about 4 seconds then i re-crank for a couple of times till it starts. I ether have to press on the gas pedal and start it starts or keep cranking it until it starts. Checked fuel and new maf and it has spark , good compression.
It runs good but it only gives me crappy fuel economy. Thanks
Could it be the crank angle sensor? or Engine cooling sensor?
Injectors are not leaking.

COLD WEATHER STARTING TIPS

This bulletin supersedes PI95-005. The Service Information has been amended. Please discard all paper copies of PI95-005

APPLIED VEHICLE(S):
All models

SERVICE INFORMATION

In case a vehicle is hard to start during cold weather, we suggest the following procedure.

^ These steps are a review of the procedure outlined in the Owner's Manual.

^ Use these steps when the weather is cold and the engine is hard to start.

1. Press the accelerator pedal down approximately 1/3 of the way to the floor.

2. Hold the accelerator pedal in this position while cranking the engine.

3. Once the engine has started release the accelerator pedal.

NOTE: Do not race the engine while warming it up.

4. If the engine does not start within 15 seconds, stop cranking, wait at least 10 seconds. Then repeat steps 1 through 3.

Once an engine is started in cold weather condition:

^ You should keep the engine running for a minimum of 2-3 minutes before shutting it off.

^ Starting and stopping of the engine over a short period of time may make the vehicle more difficult to restart.

^ It may also adversely affect a vehicle's fuel economy.


Another factor which may affect a vehicles "startability" is the viscosity or thickness of the oil that is used.

^ SAE 5W-30 viscosity engine oil is preferred for all temperatures, all year-round for most models.

^ SAE 5W-30 viscosity oil makes it easier to start the engine and maintain a stable idle during warm-up.


Please communicate these cold weather starting tips to your customers.

towards the firewall on the passenger side, over by the idle air control valve, i wanna say it's a grey plug

do you have power on one of the wires when the key is in the ON position, right before the start position.

mainly you're looking for power on the black/yellow stripe wire, that's before the subharness, it changes to a blue/red at the actual plug for the IAC air regulator valve. this wire should have power anytime the fuel pump is running

the idle air control valve (brown plug) should also have power on the brown but changes to Red/green wire at the iacv connector when the key's ON

lemme know what you got, and i'll get back to you.
