Hi...
After you have checked the BATTERY.
Check the bATTERY terminals.
Due at they are Side terminals. Lots of times they get A corrotion on the terminals.

But if you check al of this.
ON One of the common problems for this kind of vehicle is the Electrical part of the ignition switch. I Replaced a few of them.
Because they give this problems.
One of the simptoms is . They Crank but the cluster lights Don't come.
Some times they crank and running but sedently stop.
The Accesories don't work.

Check all the connectios as possible.
Repair as need.
Check if the problem is the ignition switch.
Don forget check the fuses for misscontact.

OK.. I hope this help to start disgnostic your car.
If need more information I will glad to help you.

Ere are some things to try... First, make sure all battery and starter connections are secure; then if it won't crank, at the starter solenoid (on top of starter) there are two wires, the fat one providing the actual voltage that operates the motor, and the smaller wire that carries the starter actuation control voltage, when the key is turned to "Start". being very careful not to touch grounded metal, use an insulated pair of pliers or screwdriver to connect these two posts together, delivering the always present 12 volts direct from battery to the solenoid. If the starter is good, this should make it crank, indicating a problem further upstream in the crank circuit. If it doesn't crank, you have a bad starter... You can also check this with an inexpensive 12 V test light... ground the clip lead and hold the probe tip to the smaller terminal while having a helper turn the key... If the crank impulse is reaching the starter, the light will come on, and if the light is on but no cranking it is the starter.

If the crank impulse is not reaching the starter, it could be caused by any of the things in the start circuit. The voltage that is supposed to trigger the starter originates from the under dash fuse panel and goes through a kind of self resetting circuit breaker that can be tripped by excessive current heating a short length of resistance wire sufficiently to cause a bi-metal contact strip to curl away from its mating contact and breaking the start circuit... If your problem was heat related, I would suspect the breaker. From there the voltage goes through the ignition switch, and from the ignition switch it goes through a safety interlock circuit which is different for automatic and manual transmissions.

Automatics have "neutral safety" switches that break the circuit if the car is not in park or neutral, and this switch can either be under the shifter cover or built into the transmission. You can try jiggling the shifter while trying to crank; an intermittently faulty switch will usually show some effort to crank (possibly briefly) while doing this.

Manual Trannys have a switch that breaks the start circuit if the clutch pedal is not fully depressed, mounted under the dash in contact with the clutch pedal arm. Working the clutch pedal while holding the key in crank position might produce intermittent start efforts if this is the problem.

If you can locate whichever of these switches you have, you can also use the test light to (1) see if the start signal is coming out of the ignition switch and (2) going through the interlock switch.

You can also temporarily bypass these switches by shorting together or jumpering the two connectors on the switch.

I had a similar problem with my 1991 Prelude that ended up being the starter, and it was HUMIDITY related, of all things! I had driven through some high water by necessity, high enough that the starter was submerged, and then experienced your exact same symptoms... Showed up especially in humid, cold, or rainy weather, The water had washed dirt/sand into the solenoid engagement mechanism and had eroded lubricant, causing the solenoid to bind and not fully engage. Starter replacement solved the problem!

Hope this helps you get it fixed, but don't hesitate to post a comment or question if you need more help, and best of luck!

Have the starter and regulator tested, and check the wires and connections to the starter.

Check all of the battery terminals and cables and check the wires on the starter/selonoid, start from the battery and follow the cable out and check all conections , clean and tighten them and if it still does it the starter/selonoid is bad and needs replacement...

Hope that helps..........

Either there is a bad or dirty battery connection which is allowing the lights but no crank or you could have dirty or loose starter wires or starter relay may be bad or ignition is a possibility. All these can be tested with an ohmmeter for power. I would start with connections

Daughter ran 97 ranger out of gas, now it wont start, reset the fuel pump button and have gas shooting out of releif vavle, but still wont start, tried many times. Please help. Thanks


You have fuel at the rail, now it's time to see if it's making it past the injectors. Disconnect the air intake duct from the throttle body. Have an assistant crank the engine over while opening the throttle slightly. Spray starting fluid into the throttle body and see if the engine attempts to start. If it does, then the injectors are not firing. The reason the injectors are not firing could be :
1. Blown injector fuse (sometimes marked "INJ").
2. Bad crank sensor.
3. No power to computer.
4. Computer problem (bad injector drivers).
If you have tried to start the vehicle many times, then you should start to smell fuel if it is getting into the engine. If you smell fuel, then let it sit for a while and try checking for spark. An inexpensive spark tester can be purchased from most parts stores. The reason for no spark could be :
1. Blown ignition fuse (sometimes marked "IGN").
2. Failed ignition module.
3. bad crank sensor.
4. bad ignition switch.
If everything checks out, then try disconnecting the battery for at least 20min. the longer the better. If the engine still wont start, then more advanced diagnostics will be needed to determine the problem. I hope that this information is helpful and thank you for using Fixya.com.
WARNING : Wear safety glasses when performing the starting fluid test. Keep hands and loose clothing away from moving engine parts and cooling fan motor. Use caution when working around distributorless ignition systems. These systems produce extremely high voltages which can cause severe injury or even death.

2002 impala intermitenly wont start


I would clean the battery connecters or possibly change them. How old is the battery? sometimes when battery get old, they have enough juice to crank the motor but not enough to start it..But then again, if it doesn't crank at all sometimes, it could certainly be a bad or loose battery terminals..Start with this since its the simplest and easiest and could very well be your problem. hope this helps
