2001 old silhoutte will not start

Looks like this might be the computer failing the initial self test. Check your battery voltage and if it is good have your starter checked.

Filter or valve problem in the transmission. Transmissions also need regular fluid changes and filter changes and most people do not know this. You can do this yourself, or have someone do it.

The humming would be the fuel pump coming on. It should only hum for a few seconds, then shut off.
Your problem is with the start circuit from the battery to the starter, or from the ignition switch to the starter solenoid. Check the connections at the starter (the big cable) for tightness.
Is the battery charged up enough to turn the engine over? Check by turning headlights on and observe while someone turns key to crank. If they dim a LOT, then either battery is too low, or the starter is bad and needs removing for testing. If brightness doesn't change, then the circuit from ignition switch to starter solenoid is likely not working. Check for 12 volts at the small wire to starter solenoid with key in cranking position. If you have power there, the solenoid may be bad. Remove starter for testing. If no power at solenoid in starting position, then either the ignition switch is bad or the neutral safety switch might be the problem, or the wiring from the switch to the starter solenoid is not passing current.
Good luck.

when you turn key on is there power to lights radio dash ? if yes check the starter relay and solenoid you can check easily using a test light find a good ground and a test light that works test light on battery first at the starter there will two wires one thick and will lead to battery the other wire is thin this is the wire you want to test have someone turn key to start while you test for power at wire if there is power at the wire replace starter the solenoid is deffective if there is no power at the starter sol wire then check starter relay

hope this helps leave me a comment and vote this was helpful any more questions reply

starter is probably rusted

Sounds like you have a starter issue.

If the engine will not crank but you have power everywhere else I would start by testing the starter. You can remove the starter and take it to an autoparts store for inspection.

try turning the engine by hand and giving it another try...if able as the starter is out of the way look at the teeth on the flywheel make sure they are not chewed up. if so there is your problem and a big job to replace that...if not just buy another starter and give it a try...your old starter my be having problems engaging the teeth...

Did you check to see if your old starter was any good, you may have a bad spot on your fly wheel and it is getting caught up on the bad spot and it want start try turning your fly wheel of the bad spot and then try to start it.

With a 12 volt test light and an assistant, check for a signal to (S) terminal on starter solenoid.If ok, check all connections at starter for clean and tight.If still no crank, replace starter. If no signal to (S) terminal, suspect ignition or neutral saftey switch.

please tell me what to do when the abs light and service tractions lights show on my 2004 oldsmobile silouette van
