I cant get my bravada to crank over.

I DON;T KNOW. CALL FOR FREE ROAD SERVICE

SERVICE MAN MAY DO A QUICK CHECK.
USE LOAD CELL TO TEST BATTERY.
CONSIDER CLEANING BATTERY CONNECTIONS. COULD BE STARTER. TRY JUMPER/ BOOSTER STARTING TO SEE IF HIGHER VOLTAGE
MIGHT WORK. CONNECTION AT THE STARTER FROM BATTERY COULD BE LOOSE.

Starter fluid won't work if the starter won't turn the engine over.

Get the battery load tested...it may not have enough juice to start the truck but have enough to light up the lights

check your fuses and battery connections at the starter. Is the anti theft light flashing? If it is that's your problem. Wait 10 minutes insert the key...wait for the theft light to go out before trying to start.

if that doesn't work you will need to get the starter checked...which means you will have to take it off.

hook a volt meter up to your battery you should see around 12.5 volts. Then crank the engine and see what the voltage drops to. If it drops to less than 12 volts the battery is bad.

Are you sure your battery is good and able to take and keep a full charge? The only thing in the start circuit that could cause a big drain on the battery is a shorted starter. But if you can send power and it cranks okay, I don't think you have a bad starter.

Is the ignition key on when you crank it and have no spark? Does your distributor rotor turn when the engine is cranking?

I would try a new solenoid. If it clicks it should send power on to the starter on the big cable. Make sure all battery and ground connections are clean and tight. If still a problem, buy a voltmeter and learn how to do voltage drop tests. This will help find bad connections.

Could be the cables or the starter. Remove the starter and have it tested.

you have a earth problem/neg on battery check the battery wires i suspect a dirty connection.get that starter checked again and test the most common problem[ THE BATTERY].adrian,,,,

This may be a long shot, but try re-setting your ECM. Remove the negative battery terminal, wait a minute or so and re-fit it. This will re-set the module and return it to default values. From here you can begin diagnosing if you still have problems

STARTER ASSM HAS SOLENOID ON IT

Hit the starter few times with metal object (hammer or pipe or some sort) while someone else is holding the key in START position. If car starts, your starter is NO GOOD. This is a quick test. There is more testing that you could do, but start there. Whack it with something.

Chech the electrical circuit from the ignition key to the starter motor
To test this circuit an automotive test light is needed.
Attach one end of the test light to engine ground and the other end at the starter trigger terminal of the starter solenoid.
The test light should illuminate when the ignition switch is activated (crank engine over).
If the test light illuminates the starter motor/solenoid has failed and needs to be replaced.
If the test light does not illuminate suspect a neutral safety switch or clutch safety switch if provided.
A wiring diagram is needed to trace power from the ignition switch through the safety switch and down to the starter solenoid.
Replace failed components as needed and recheck system.
