The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

it sounds like either your having a short at the starter or the ignition switch is bad, I am leaning towards the issue being the starter, usually when the ignition switch is going bad there will be no click,

SOURCE: it takes three plus times turning the key to start

Take your car to your local parts store and have them load test the battery, this will be a pass or fail test

If the battery passes the load test. Replace ground wire on battery all the way to the engine.

We believe the the Ground wire has corrosion in the wire or over time now has too much resistance to get the power to the starter.


Hope the tip helps.

Hard to start when engine warm?


You dont need a code reader,you have a OBD1,to get the code you jump two wire together and count the flashing light,Beside we have the symptoms, Hard to start when warm, The ECT (engine coolant temperature) can do this.This is a thermistor it changes resistance and decrease voltage when engine is COLD. To diagnosis this sensor will cost you more than just to replace it.Its location is on top of the thermostat housing, As for choosing the right gear beside requiring ATF4 is the input speed sensor this sensor has a high failure rate and is resposible for reporting to the output signal. This sensor is located at the driver side of transmission,to the front of the manual shift lever.Also the output sensor has a high failure rate this is located at the rear of the manual shift lever.

Program new key for montana


As long as you still have one that works, it's easy.
1) Insert the "original" (working) Key.2) Turn the Ignition to ON (RUN), but do NOT start the engine. Turn the Ignition OFF and remove the key.3) Within 15 seconds insert the new key and turn the Ignition to the ON (just to ON, not to START) position. The Security indicator should light up for about 2 seconds to indicate that the new key has been programmed.
At that point, it should work. I don't know how many different keys you can get the Theft Deterrent Module to recognize; there may be a limit.
If you're don't have a working key now, it's much more time-consuming;the procedure to get the TDM to recognize a different key takes about 30 minutes when you don't have an old one that works.

My 2003 saturn ion will turn over but willnot start


You may have two issues, one with starting and running while the other may be ignition lock cylinder related. You may be able to try using the spare key if you have one otherwise its recommended to have one made by Saturn and try it before determining that its a worn out lock cylinder. Then Saturn may be the best choice to at least configure a new lock cylinder with the original keys to match. The lack of engine firing up may be a simple cps failure.

The engine turning over but never firing up may be related to the crank position sensor (CPS) as long as you don't see the security light flashing in the speedometer or tach. The security light flashing would mean the factory anti-theft deterrent system is preventing engine running by disablng the fuel pump. No fuel pump = no engine run. Determining a faulty cps is by way of observation - the spark from the ignition system is observed. Remove the spark plug wires, noting the firing order carefully, from the coils and have someone crank the engine over so you can watch for expected sparks across the coil towers. A lack of sparks usually means a failed cps as the only other failure would be the ignition module that the two ignition coils mount onto. The cps is mounted behind and above the starter with one 10mm bolt. You can buy it from any auto store stocking it.

2005 chevy malibu i replaced ignition now it starts for one second then turns off is can i directly permantly insert the chip from the key directly into sensor box which is cinnected to the ignition &...


A common problem is the ignition cylinder and/or the ignition switch. With the buzzing of the relay, i would say all this may be related to the ignition switch. A low voltage supply to any of the circuits that the switch feeds will give strange electrical conditions. If going to replace the ignition switch, then also do the cylinder at the same time. With all things described, sure sounds like the ignition switch. P.S. The locks may be related to the ignition switch problem or not at all. With that said, would suggest looking at the BCM(body control module)It control locks, and also has alot to do with the security system. See picture at bottom of this page of corroded BCM connectors. 4- Passlock Ignition lock
cylinder removed.
Install new cylinder.Try to start- it wont or dies.Leave key on for 10-12 minutes, or until light goes out.Then turn off key for 10 seconds.Turn key to 'on' position for 5 seconds, then turn to start

Driving the car and it died going down the road.. i think it might be my fuel pump, but im not sure


http://www.youtube.com/user/scottykilmer#p/search/0/WLA6syjt08o

Could be a distributor problem; see video above.

The fuel pump should humm for a few seconds when you turn the key to the run position. You can remove the gas cap and listen for the fuel pump to run while someone else turns the key.

If your timing belt breaks then your engine will stop running.

The Master relay has a habit of going bad due to poorly soldered connections.

I have a 96 pontiac grand am that doesnt start all the time


Starting Problem # 1: Engine Won't Crank At All

Scenario: You turn the key, but nothing happens: And by nothing, we mean there is no dash light, no sound, nada. The first thing you should do in this case is to pop the hood and check the battery. Either the battery is completely dead or there's a wiring problem in the starting system. Try jump-starting the battery. If that doesn't work, you'll probably have to call for assistance.

Scenario: When you turn the key, you hear a rapid clicking sound, and the dash lights dim. This is your classic low-battery symptom. Jump-starting the battery should get the engine to start.However, if you keep experiencing this problem, you could have a bad battery or alternator, or it could be some­thing as simple as a loose alternator belt. Take your car to a mechanic just as soon as you can.

Scenario: When you turn the key, the lights on the dash come on, but you don't hear anything. Make sure you have the shift selector all the way in park. Move it out of park and then back, or try starting it with the shifter in neutral. If your car has a manual transmission, make sure you have the clutch pressed all the way to the floor. If that doesn't help, you can try jump-starting the battery, but it probably won't work. There's a good chance your car has a bad starter or a problem in the starting circuit. That could mean a prob­lem in the ignition switch, neutral safety switch or starter sole­noid.

Scenario: The dash lights come on when you turn the key, and then go right out, and the engine doesn't crank when you turn the key to start, But, the lights slowly come back on when you release the key. This is another classic: the bad battery connection. When you turn the key to start, the starter pulls so much current that it breaks the connection. Then, when you release the key, the connection slowly comes back. The connection provides enough power to turn the dash lights on, but not enough to crank the starter. Cleaning and tightening the battery terminals may fix this prob­lem.

Scenario: When you turn the key, you hear a single, hard clunk. Turn the headlights on and try again. Do the lights dim slightly when you turn the key? If so, you probably have a bad starter or a seized engine. If the headlights don't dim at all, or just barely dim, there may be a connection problem between the starter solenoid and the starter itself.

Scenario: When you turn the key, you hear a loud, scraping or grinding sound like metal on metal. The starter drive is bad, or the ring gear on the flywheel damaged, or both. You may get the starter to engage if you try turning the key a couple of times, but let go of the key right away if you hear the noise again. If the car does start, you should drive it right over to local repair shop and have the problem fixed.

Starting Problem #2: Engine Cranks but It Won't Start

Scenario: The engine seems to crank normally, but the engine doesn't even sound as if it's trying to start. Is there gas in the tank? Gas gauges are notoriously inaccurate. If you have to move your head to one side to get the needle to move off empty, try adding some gas to the tank.

Scenario: When you first turn the key on, you don't hear the fuel pump run. In cars with electronic fuel injection, you should hear a light hum a few seconds from around the fuel tank. That's the electric fuel pump running. If you don't hear the fuel pump run for a couple seconds when you first turn the key on, try cranking the engine until the oil light goes out. That may start the pump running and allow the engine to start.

Scenario: The engine cranks normally, and it sounds like it wants to start, but it won't. You may have flooded the engine. Hold the gas floor and try again. (Let the gas pedal up when it finally starts). If it's raining out, the ignition system may be wet.

Scenario: The engine cranks unevenly in a repetitive-sounding pattern. You may have a bad timing chain or timing belt. Call a tow truck and have it towed to the repair shop.


Starting Problem # 3: Engine Starts but It Shuts Off

Scenario: The engine starts right up, but shuts off as soon as you release the key. This is the classic symptom of a bad ignition switch. A new switch should fix it.

Scenario: The engine starts and runs, but when you put the transmission in gear, the car lurches and the engine shuts off. The converter clutch in the transmission torque converter probably is engaging when it shouldn't. On some cars, you can bypass this by disconnecting the torque converter clutch solenoid; but unless you know which wire to pull, forget about it. Call for assistance.

Scenario: The engine starts and runs, but seems to idle slowly and stalls when you come to a stop. This probably is a fast idle problem. When the engine is cold, it's supposed to idle a little faster than normal to keep the engine running. You may be able to drive using two feet until the engine warms up: one on the gas to hold the idle up a little and the other for the brake. However, don't keep driving it this way. Take your car to your repair shop just as soon as you

You're not gonna believe this. Your problem sounds like the fuel pump. Put a pressure gauge on the regulator under the hood. You should read about 30 .p.s.i. I don't think the sun has much to do with it. I had the same issue before.
