Hi and welcome to Just Answer.My name is XXXXX XXXXX i'll be glad to help you this evening.
How long has this been an issue?Did it just start?
I havn't had past problems with the car. Drove it to the gas station fine and then went to leave and it wouldn't start or even turn over
If you shift the car into neutral will the car start?
Im not sure. I can check but it will take me a few minutes to drive over to where the car is
The code 21 is for the oxygen sensor.This fault will not keep the car from starting.
OK I'll stay on.
Also turn on the head lights and check to see if they stay bright or do they dim when you crank the engine.
ok I will check. I havnt been able to get the engine to even crank in the past
Check the battery terminals and make sure they are tight.
I will. the battery gauge reads normal
the engine won't crank in neutral and the battery terminals are tight
the headlights don't dim when i try to start the car
The neutral safety switch on the transmission,the ignition switch on the column or a fusable link near the positive battery terminal may have failed.One way to get the car started and home is to unplug the starter relay and remove the cover to manually close the contacts to see if the car will start.
should i just try to replace the ignition switch first?
Try swaping the starter relay with another relay in the power distrbution center.If it does not start then you still could have an ignition switch or neutral safety switch issue.Do you have a test light?
how do i identify the starter relay?
i probably have a test light at the house
I'm sorry i had a connection issue i'm still here and i'll answer your question
The stater relay is on the drivers shock tower. There should be 2 relays there.The stater relay is the one closest to the drivers fender.
should i switch the starter relay with the one that its next to?
It might or might not work because some of the relays have different monting bosses in the covers.
yea they don't fit..should i just replace the relay or is there a way to test it?
Can you hear or feel any clicking from the relay when you crank it?
no i don't hear anything
ok...more than likely the ignition switch has failed and needs replacing.
how long would it take me to replace it myself?
At the most maybe an hour and a half.
ok i will try to do that next week. can i message you if i have any other questions?
Yes please do.I will be here if you have anymore questions.
do you think the O2 sensor also needs to be replaced?
ok thank you
The chat will be open for 7 days.I will check back to see if you need anymore assistance...ok? Thank You for choosing Just Answer...Ric.
