You may need to replace the starter and solenoid. My car had the same problem. I just tapped on mine until I could get it replaced the next week. It may have a flat spot. Somehow tapping on it moves it enough to make it turn over.

I think I may have triggered an anti theft kill switch on my 03 expedition 5.4. It has a viper alarm, but I found a spare and activated the door code and now it won't start. Everything else comes on.

Engine code 25 26


man there is a lot of chatter about those codes and O2 sensors. I do know my truck popped a couple of those error. It ran rough and generally made my truck upset. I finally ran it down to the dealer and they said it was a broken spark plug. This happens to me in the winter. Run it by a dealer, but first pop the hood, start the engine have a friend rev the engine a couple times and see if you see an odd light from a spark plug or two. Best if this is done at night. Just be very careful not to reach in while the engine is running. Just watch. If you see the blue light, kil the engine replace that spark plug and retest. You can read here what some other tried:

Symptoms of a bad map sensor on 93 cadillac fleetwood brougham


Well code 23 is a faulty signal from the manifold air temp sensor. The sensor is telling the computer the air temp in the intake is out of range compared to the other readings.
Code 26 is a quad driver problem inside the computer.
Code 34 is a MAP sensor signal saying the vacuum is high when it should be low compared to the other sensors.
They may be connected or separate issues. You could check the MAP with a vac gauge.
I would clear the codes and see which ones come back again.

1989 lesabre engine codes


26 is a quad driver failure, 41 is a cam sensor failure. I can give you a test procedure for 26 but for 41 you likely need to replace the magnet that is in the cam gear for the cam sensor pick-up.

The ECT (Engine Coolant Temp) sensor is most likely bad. Common problem with Saturns.
