It used to be a hit and miss kind of thing, now it won't start at all. Battery is not an issue. Rumor has it these cars are notorious for this, but nothing tried has worked. Changed relay for security system, ignition switch and everything. (All the cheapest ways to trouble shoot...) Anyone have this before and can suggest how to fix it?1991 Cadillac Sedan Deville won%26039;t start?
Well if it is cranking (trying to start) then check for spark with a timing light, old sparkplug that is grounded, etc,
if there is no spark then check the output from the crank Position Sensor (a GM Problem), check for 12V at the coils, and check that Ignition Relay (swap with a known good) It may be your ECU in which case I would get a replacement at a junkyard
If you have spark then check the fuel pressure, and the fuel pump fuse and relay, if the pressure is fine make sure that the injectors are pulsing a Volt-Ohm Meter will show you if there is power to the injectors. Visually make sure the injectors are not leaking. If the injectors are not getting any voltage then it could be the ECU.
If the car will not crank, check the ignition switch, check that the cables to the starter are good, and see if you have 12 V at the starter. Test the starter motor. If you have an aftermarket alarm check that the alarm system is getting power and functioning correctly1991 Cadillac Sedan Deville won%26039;t start?
Sounds like it jumped time. Check that next, if not that check your fuel pump. Good luck.1991 Cadillac Sedan Deville won%26039;t start?
My Buick did that. What was wrong was the crankshaft postioning sensor. Since then it was fine. My brothers 94 Olds did the same thing. New sensor. No problem.
I don't know for sure what or where one is but I know it costs me $75.00 at the garage. And, to me, it was money well spent. I think it was an early 90 GMC problem.1991 Cadillac Sedan Deville won%26039;t start?
You might have a bad starter/alternator or maybe some of the wires could be lose.1991 Cadillac Sedan Deville won%26039;t start?
I bought a new 91 caddy back in 91 and had the starter solonoid replaced . sometimes car would be fine and the next time it would not do anything .

At-mt swap on civic key is being held in ignition cylinder, WHY?
95 civic was originally an automatic but i converted it to manual trans. I changed the brake light switch then after checking my bulbs, the key wouldn't come out of the ignition. I disconnected the battery then the key was released and I was able to take it out.....HOW do i fix this??At-mt swap on civic key is being held in ignition cylinder, WHY?
I don't know the wiring on that, but the key cylinder does not believe the car is in Park so it does not release the key.rodents tvs

I have a 1989 cadi deville and i was wanting to change the?
ignition switch but i have no idea how to do it so can some one tell me how i would do it or send me a link on itI have a 1989 cadi deville and i was wanting to change the?
u need a puller 4 the steering wheel,a variety of small torque bits,investing in a chilton or haynes book would b your best bet 4 every car is slightly different in removal,there is also another tool that may need required 2 compress unit back on 2 put snap retaining rings back on or steering wheel will b wobbly,not a very hard job,but pay attention of order of parts removed,have proper tools.

97 Chev 5.7 ltr starts & runs then shuts down?
The battery died from repeated start %26amp; quick shutdown. A few days after reading posts, I installed a new dealer ignition switch with wire harness. I didn't change the ignition cylinder. I installed a new battery and the vehicle started fine. I started %26amp; shut it down several times to check if it was operating correctly. Alternator appeared to be charging properly. Vehicle was performing normally. After 1/2 hour I shut it down to button up the covers and when I finished the job, it started doing the same thing again. The only adjustment I made was to snap on the plastic ignition cylinder butterfly over the key insert. Does the ignition cylinder have some electrical component that controls spark %26amp; fuel? It will rev up if you press the gas pedal then it dies like the spark is being cut out. Could there be some theft deterent system malfunction at work? Can I bypass this some how? Is there an electrical component to change?
Any ideas?97 Chev 5.7 ltr starts %26amp; runs then shuts down?
This is probably a vortec 350 small block-they are great engines, but the electronics can be maddening-here is a hint-make sure this is not a fuel pressure related problem, rule that out by checking the pressure after it dies on the down side of the fuel filter. If that is ok, then use an obd tester to see if the system is giving any trouble codes. If nothing, get it to a reputable shop. The only way to alter the theft deterrent system is to reprogram the computer.97 Chev 5.7 ltr starts %26amp; runs then shuts down?

Try cleaning the resistor on the key. Sometimes when they get dirty it can cause stupid problems like this because of the theft system.

88 toyota 4 wheel drive removing the ignition key switch? and how?
put new starter on 88 4 wheel drive truck , when i turn the key to start i get a click like no power to the starter, i have have changed the starter, im woundering if it might be in the key switch sending power to the starter ? and are the anything i need to check ? how do you remove the key switch? someone told me there is a pin you push in. havent found it any help will be thankfull,,,,,,,,,,,88 toyota 4 wheel drive removing the ignition key switch? and how?
the key switch (ignition switch) only sends a small amount of power to the solenoid and the solenoid makes the connection from the battery cable to the starter because the small wires coming from your ignition switch can not carry enough power to run your starter your problem is probably your solenoid or you have corroded battery cables if so clean them the ground or positive cable could also be loose at either end
I'm assuming you have already made sure your battery has a full charge88 toyota 4 wheel drive removing the ignition key switch? and how?
How do you KNOW the %26quot;new %26quot; starter is good? Key sounds OK! Charge your battery, clean your battery terminals AND posts with a wire brush. make sure all the BIG connections are clean and firm-tight enough, not overdone. repeat on the starter motor. Make sure the Earth cable goes to the chassis AND the motor and that these points are clean and firm. If battery %26gt;3yrs old, or left unused too long, may be shot. when you replace it, use Cadmium Sulphite solution in the new one to retard sulphation and failure. It works!!! If all else fails, short out the 2 big bolts to each other only on the stater solenoid with the forks of an old spanner, and it should spark %26amp; spin fast. If not, it's battery or starter. Starters are easy to recondition, as are alternators. The usual parts (bearings %26amp; brushes) are very cheap.

How hard would it be to change the following on a 1988' jeep wranlger 4.2 6cyl...?
ignition system, coil, ignition switch, ignition module...or to check if they are working rightHow hard would it be to change the following on a 1988%26039; jeep wranlger 4.2 6cyl...?
real easy, if you know what you are doing or looking for. My guess is you have no spark. start from the starter relay to the ballast resitor and on if you can find them get a qualified mechanic to look aat it before you thow parts and money at it and the truck still wont startHow hard would it be to change the following on a 1988%26039; jeep wranlger 4.2 6cyl...?
fairly easy..
it's an inline 6, the coil is 3minute swap, ignition system, meaning plugs and wires.. pretty easy to change those.
ignition switch is under dashboard, probably mounted to steering column on the topside.
module is either under the distributor cap or mounted close to it.How hard would it be to change the following on a 1988%26039; jeep wranlger 4.2 6cyl...?
No more than a 100 dollar job at the chop shop.How hard would it be to change the following on a 1988%26039; jeep wranlger 4.2 6cyl...?
Easy just like the others noted. The thing here is what are you trying to fix?

2002 impala wont start?
i have a 3.8 impala and i just changed the switch of the ignition now it wont start i put the old one back on and it wont start either i got it to start straight from the starter but it shuts off. what can this be and how can i fix it also everything turns on just dosent crank at all2002 impala wont start?
yea i have heard of this before with some of the new cars the computer thinks you are trying to steal it so it shuts down the car
also you might have blow a fuse some where or crossed wires with something just a guess with out really looking at it2002 impala wont start?
call the dealer, you might have flashed your computer ( security )
they will have to program ithide my myspace friends what is the name of
