It's never a good idea to just replace parts to attempt a repair. First find out WHY the engine will not start. By replacing parts you have introduced other possibilities into the possible reasons for the engine not running. Always go back to the basics: Fuel, Spark and Compression. If you have the three in the proper timing, the engine should start. You did not mention if the engine "cranks" when you try to start it but since you claim that the starter is ok I'll assume that it cranks. Check to see if there is a spark. Pull a spark plug wire, either use a tester or connect a spare spark plug to the wire and set it on the engine block while you attempt to start the engine. If you get no spark, trace everything back to see if voltage is getting to the coil before replacing the coil. Same thing with fuel. See if there is fuel pressure to the injectors or if there is fuel at the carb if it isn't injected. Get a compression tester to see if something bad has happened internally. If the timing chain/belt has slipped and you have no compression the engine will never start. It's always a matter of going back to the basics.
Since you changed your battery and starter I'm assuming you are getting fuel and spark is your problem. You should check your starter relay, the wires from the relay to your starter, the wires from your battery to the relay, the wires from your locking cylinder to the relay, and your locking cylinder. You might also check your alternator. You can take it to a parts store to have it bench tested for free.
Remove the starter and haeit checked at auto parts for amp draw Check the alternator to see if it is keeping the battery charged Check engine ignition timing may be too far advanced
Assuming it started and ran before you changed the battery, and changing the battery actually is when the problem began, the starter relay wire has been left off and needs to be connected at the battery terminal. I would need more information to diagnose it further.
Interesting?? I had my starter and battery replaced on my 2002 Saturn VUE and within a few months my low beams ands daytime running lights went out. Dealer says the post in the fuse block is burnt and the entire block needs to be replaced at a cost of over $600.
I means you have a battery problem or a starter problem or dirty/loose battery cable connections. If the battery is operating the starter and the starter is turning the engine over but the engine won't start and run, you may have a spark problem or a fuel problem.
Sounds like the ignition switch.
That depends upon what the starter problem is. If the battery is exhausted, you can use another vehicle's battery, with jumper cables.
Check the battery cables or starter.
your battery is dead or the starter solenoid
Dead battery? Loose or dirty battery cables? Bad starter solenoid? Bad starter? Neutral switch?
is the battery fully charged?
purple wire comes from park netural switch .yellow wire come from ingintion switch to park netural switch
