Ignition switch problems

I have the same issue. Sometimes it starts and sometimes it does not. I never know when but typically (when it doesn't start) if I let it sit there anywhere from 20 minutes - 2+ hours... it starts up no problem. I have replaced the knock sensor twice and it works for a couple of moths. I take it back to the mechanic and it is burned out. He replaces it and same thing happens a couple of months later. Today it is in the shop again for a 3rd time with same problem. Also, the start engine light is on and I went to Autozone for free diagnostics test and the sensor is what it came up with. Ideas? Help! I love my car even if it does have 193K on it, runs excellent.

I have the same problem with the same model year. Replaced battery, starter and control module. Dealer doesn't have a clue.

2003 Saab 9-3 convertible.  Frequently fails to start, but then starts after a wait of 5 minutes to 2 hours.  These events have nothing in common, (weather, time of day, driving conditions, etc.) Dealer replaced starter and no change.  Battery okay and start assembly is apparently ok, since it's new and the car does start most of the time.

My ford van is doing the same thing, engine turns over but sometimes doesn't start, wait a few minutes or move from part to drive and pack it starts?

Starter sometimes engages. Other times I just get a 'click' or nothing at all. I wait for a short period of time, turn the key and the engine starts. I'm assuming it's the starter contactor (if there is such a thing) but I have no idea where to look for it. I can't afford to pay for diagnostics at the dealer and want to fix it myself if that is an option.

My 1989 Mazda B2600i will start and stay running only if I hold the key in the start position. I noticed I have to play with the key in the neutral pwr. position to get the dash lights to come on. What's the matter?. Thanks, Ole.

can anyone tell me if it would be in my ignition.... my pathfinder would not start on x-mas eve (right when i was packing up the truck to go to kamloops), So we changed the solenoid..... now it starts only when it feels like it... what should i do?

1998 CABRIO 2.0 picks when it wants to start.

its NOT the starter or battery.

few people online with the same problem seem to have the issue when they are also around water. It is raining outside today and my car wont start. Those people usually wait (that would give it time to dry right?) and it will start and they issue is fixed with a new coil. Sounds like a possiable solution to me.. i will def try this bc i have had problems when i have gone through really big puddles and when its wet outside...

the starter engages and turns the motor it just doesnt want to start.its not every time or even real often but when it happens it just happens.

6 mos. ago wouldn't start, ran a hot wire from battery to ignition switch, Started fine. For the last 2 mos. I have to pump it 10 times & hold throttle wide open to start it. Now It wont start at all, it gets really close though.

same problem, car wont start then when i let it sit it starts. this morning it wont start any more

starts sometimes and shut off twice while driving. mechanic replaced fuel pummp 3 times still starts sparatically

I just came across this post in a google search. I have a 2002 IS 300 with 100000 and it took two times for it to turn over this morning. I hope this doesn't pose a constant problem!

Replaced starter, still does the same thing. The old starter turned out to be fine. Cleaned battery cable connections. Not that either... Ignition?

I have the same car, with the same problem. I have been told that its either the ignition cylinder or the ignition switch. I have had my battery, starter, and alternator tested all are fine.
