1996 LeSabre Engine will not crank over

Engine will not crank over with the key.
Engine will crank over and start if the solenoid is jumped.
The engine will run for about 5 seconds then shut down.
It will restart immediately by jumping the solenoid.
Any suggestions...
Thanks.

    It cranked over and started for a second then died. Now it will not even crank over. This happened before and jumped it and it started right up. What is wrong?

This fix was for a 1996 Buick LeSabre.
I found the key reader in the ignition switch was faulty.
Made up a resistor pack to match the key resistance, cut the orange wire which comes out of the steering coloumn (it contains two white wires) from the reader to the VATS module and soldered it into the two white wires going into the VATS module.
This bypasses the security system so now any properly cut key will start the car.

How to diagnois problem with no scanner


Eliminate the battery as the issue first up.
Check if you can jump start the car from another vehicle with its engine running or at least have the starter motor kick over the engine. If it starts then you know your battery is the issue. Having lights does not mean the battery has enough cold cranking amps to turn over the starter motor.

2. If the starter cranks the engine over as normal with a jump start from another car but your engine does not start you have also eliminated the starter motor as the issue.

3. If it does not start and the starter motor will not crank the engine over either when you jump start from another vehicle, then there may well be a problem with the starter solenoid, the starter motor itself or with the wiring to the starter solenoid or to the starter motor. No power getting to the starter motor solenoid or to the starter motor and obviously the starter motor will not turn over.

4. So I need not write much more here, there is a very good guide to solving starting issues here which I suggest you might like to read.

Engine won't start turn


no crank
1: battery dead, not charged. does it jump crank?
2: bad battery (corroded clean em) cables lugs. (4 ends)
3: bad starter /solenoid, assembly
4: engine seized, (turn it by hand you cant?)
5: bad key line, (from key switch to PRNDL to stater , no connections)

jump start it, if passed test, battery bad/discharged , and if fail?
you then (battery is good)
hot wire the starter solenoid, keys in pockets
fail? yes, bad starter, seized engine. turn by hand , now you know.
if passes hot wire test, bad key line. (tiny wire)

easy huh?

I have a 1996 Chevy Suburban 1500. No crank or any noise or sound when trying to start. Battery is good, even tried jumping to make sure. Could this be the starter? If so, where is it located?


The starter is next to the side of the lower engine block where the engine and trans meet(I believe on the passenger side on GM V8s)You should get 12 volts on the small(purple?) wire of the solenoid when the key is turned to "start".If you don't get 12 volts when the key is turned,it could be the switch on the shifter(usually referred to as the PRNDL switch)IF you get 12 volts at the solenoid when you turn the key,replace the starter(my Chevy work truck has gone through 6 starters(ONE A YEAR)since I've had it!)

the security ignition key reader is at fault. A chip is embedded under the keys plastic head. If the module can not read the key no longer the engine will die out after starting.

I have a 96 Dodge Intrepid and it wil not start. it clicks when you try to start it. All of the lights in the car are on. the battery has been charged. it cut off on me a few days ago and i thought i...


solenoid clicking, troubleshooting steps: Run 3 tests to troubleshoot.

1. try to jump start at battery terminals
2. unhook the jumpers and try to jump the solenoid following procedures at http://www.fixya.com/cars/r6222268-engine_doesnt_crank_turn_over (see picture there--make sure car is in park or neutral)
3. Only if #1 and #2 fail to crank the engine, smack the starter motor (not the solenoid) with a hammer and then try to start.

Based on results of above tests, here are solution options:

If smacking the starter is the only test that worked, you have a dead spot on the starter commutator--replace the starter.

If it will jump start but will not crank by jumping the solenoid, check to make sure the battery terminals are clean and tight.

If it will not jump start and will not crank even by jumping the solenoid, the problem is either the cable to the starter or the starter/solenoid itself.
check the big red wire that goes from the battery to the starter and make sure it is strong and tight at both ends. If that is good, replace the starter/solenoid.

If it will not jump start but will crank when the solenoid is jumped, the problem is with the start circuit not getting sufficient current to the solenoid. This usually only happens when there is a separate starter relay (in the engine compartment relay box) that is worn out. Replace the starter relay.

Please let me know if you have questions.

a starter that is bad is bad and no way to jump it this way
