The symptoms described indicates a fault with the ignition switch. Here are procedures for testing the ignition switch.
IGNITION SWITCH Disconnect ignition switch connector. With ignition switch in specified position, check continuity between specified terminals of ignition switch connector. If continuity is not as specified, replace ignition switchRead more: http://www.justanswer.com/questions/2j349-i-have-a-1993-toyota-camry-4-door-2-2-4cyl-problems-are-no#ixzz0dZrxv2RT

Terminal 4 and 10 should be hot at all times.Read more: http://www.justanswer.com/questions/2j349-i-have-a-1993-toyota-camry-4-door-2-2-4cyl-problems-are-no#ixzz0dZsITjfh
The connector of the ignition switch looks like the second diragram.
1 . To gain acccess, remove upper and lower steering column covers (it may be necessary to first remove lower instrument panel trim panel). Remove outer plastic trim cover from lock cylinder assembly (if equipped).
2 . Disconnect ignition switch electrical connector(s). Remove screw(s) retaining ignition switch to lock cylinder. Remove ignition switch from lock cylinder. To install, reverse removal procedure.
Above are removal pocedures for the ignition switch. After removing the steering covers you would be able to notice the ignition switch , at opposite end of where the ignition key is inseterd.
You would need a DVOM for continuity tests. If you have a test light, backprobing the terminals Read more: http://www.justanswer.com/questions/2j349-i-have-a-1993-toyota-camry-4-door-2-2-4cyl-problems-are-no#ixzz0dZsouJfy

ReplyDeleteYou have been given some good advice here. My question would be, are you hearing 1 click when attempting to start or a series of multiple rapid clicks? It does make a difference.
1 click would indicate the common starter solenoid contacts problem as I stated above.
Multiple rapid clicks indicates a weak battery, corroded battery cable connections at the battery or starter itself, or even bad cables.
Remember, a weak battery could be a defective battery, a defective alternator or even a loose alternator belt. All these things must be checked. I would start by checking the voltage of the battery itself with your digital volt/ohmeter, as suggested by someone above, with the car not running and then with the car running. Taking the car or the battery itself to an auto parts store that can check all things, would be a more difinitive test.

ReplyDeleteIf you are hearing 1 click, you have the very common "starter solenoid contact problem". The contacts inside the starter's solenoid wear and no longer allow current to pass throught them to the starter. This results in a no crank situation.
ReplyDeleteDo a search on this forum for "starter contacts". It has been covered numerous times. You can varify this the next time it happens.
Have someone hold the key in the start position while you get out and give the starter a tap with a hammer or good size wrench. If the starter now cranks the engine, you have verified the starter solenoid contact problem.
You will need to replace the starter's solenoid contacts or replace the entire starter with a new or rebuilt unit.
One other option is to remove your starter from the vehicle and take it in to an auto electrical rebuilder in your area to have your original starter rebuilt. This is an option I prefer if you have the original OEM Toyota starter.
However, these rebuilders are becoming harder to find all the time.
If you are hearing multiple rapid clicks then you have a battery problem, an alternator problem where the alternator is not charging the battery, a loose alternator belt again resulting in the alternator not charging the battery, or a problem with poor/corroded connections at the battery posts/terminals or at the starter itself.

2 possibilities
1. the neutral switch is bad. The battery voltage drops at there and can't activate the starter.
2. internal contact points of the starter are worn.

ReplyDeleteSTARTER CLICKS ONCE BUT DOES NOT TURN ENGINE
Q: Often my starter will just click and not turn over the engine. It will do this for a long time, but eventually it will act normally. Is this a common problem with Camrys? How can I fix it?
A: Yes, it is a common problem with Toyota starters. Many times, the problem is sticking starter solenoid contacts. See the following links for descriptions on how to replace them. This is a really cheap and easy fix on a Camry and should be the first thing you try after you check all the cable connections and the battery quality.

what about turning the engine off but the starter keeps going?
