The truck will start for 2 seconds then die.

Question:

I have a 1998 Chevy S10 pickup with a 2.2 4 cylinder engine and automatic transmission. The truck will start for 2 seconds then die. I would like to add that the security light is on.  I tried unplugging battery to reboot computer .

Answer:

If you can hold the key in the start position and the engine continues to run, then you need to replace the ignition switch ( not the key and tumbler, the ignition switch ).

If it does not continue to run, Then you will need to have your fuel pressure checked. Fuel pressure should be 41-47 psi. If less, then you need to replace the fuel pump.

The Security light should be on, this is normal… unless the key you are using no longer has the chip in it… The security light will come on and goes off after the vehicle is running for a few , then the lights go out ….. the check engine light should come on too, along with the seat belt light…. all normal.

car overheating

Question:

I have a 2000 Olds Silhouette and it is overheating. Why is the car overheating with a new radiator and hoses just installed?  Car overheated, so our local garage supposedly traced the leak to the radiator and replaced the radiator and hoses. Today it overheated again on the highway. 

Answer:

It’s not hard to figure out what is wrong when an engine is overheating. Every time one comes to me, I follow this exact same process, and it has not done me wrong yet.

You should start with a cold engine that has a completely full cooling system, that doesn’t have any visible leaks. Some engines have a bleeder screw on the top of the cooling system, this is for a reason. When you fill the system, have the bleeder open and add coolant until it comes out the bleeder, then close it immediately. Most vehicles also require you to run the heater on high, while filling the system. This will get all the air out of the system.

why does my air conditioning only blow out of defrost

Question:

I have a 2002 Ford Windstar 4.0 and it only blows out the defrost vents. What is wrong with my air conditioning?

Answer:

You have a vacuum leak between the source vacuum (the engine) and the heater a/c control head. When vacuum is lost the default setting is defrost (that way if all fails, you will still be able to see).

The most common place to loose vacuum in under the passenger side of the dash where the vacuum line comes through. If you look under there you should see a grill that covers the recirculation inlet and there should be 2 vacuum lines attached to the a/c box. Chances are one is attached and one isn’t. If they are both attached, then you will need to get into the engine compartment and find that line. It is unhooked somewhere.
 

My engine warning light came on

Question:

My engine warning light came on and the dealer said the 2002 Acura RSX with 99,000 miles needed a $1,000 catalytic converter. I took the car to Auto Zone and they reset the engine warning light after running the diagnostic check. I have driven the car about 200 miles and the engine warning light has not come on again. How long do I need to drive it before everything resets prior to running a new emissions test?

Answer:

Typically if the check engine light was going to come back on it would have by now. Usually there is a secondary cause for converter failure i.e. engine misfire, raw fuel being dumped etc. As to running new emissions test I would have it done so long as check engine light is off. These vehicles are sensor-ed to the point that anything at all pertaining to emissions will trigger the light on.

I have a 1998 Lexus GS-300. The car won’t start ?

Question:

It’s a 1998 Lexus GS-300. The car won’t start. Interior lights work, no head lights. When ignition key is turned there is a sound coming from a fuse box that buzzes. I tried a jump with no success. The buzz sounding fuse box is located on the driver”s side in the engine compartment. there a four of them. Blue, green and pink are the colors. The fuse box is labeled “fuses and relays.

Answer:

If you still have the original battery in the vehicle I recommend replacing it first.(9 out of 10 no start conditions are caused by a bad/internally shorted battery)

There is a Starter Relay that receives power from the ignition switch and then sends power to the starter. Most likely this relay needs to be replaced. It is located in the Fuses and Relays box you described. To test, you can just swap it with a new one or you can use a multi-meter and check for battery voltage at the “s” terminal on the starter solenoid (small wire) while someone holds the key in the start position. If you see battery voltage at the “s” terminal and it does not turn the engine over, you need to have the starter replaced.
