Welcome, I'm Chris (aka Moose).

Will the engine at least crank?

What is the theft light doing with the key in the run position?

With the key in the run position is the check engine light on as well as the odometer reading?

What is the fuse ignition switch number

Engine won't crank
Customer: replied 1 year ago.
the light is automatically on my radio keeps going on and off as well
Expert:  Chris (aka- Moose) replied 1 year ago.

The fuse for the ignition switch is #102 under the dash. When your ready for me to help you diagnose what is wrong, let me know.

If your confused on what to do now. You have already been charged the full question value. It's now time to compensate the tech that helped you. The only way I can continue to work here and help customers is by getting rated. If your not pleased yet or plan not to rate me. Let me know so I can help more, close the post, or opt out. Please let me know if you are pleased with my help.

Thanks Moose.

Are you good to go or are you needing more assistance. Just checking in before I log off for the night.

Customer: replied 1 year ago.
We still need help
Expert:  Chris (aka- Moose) replied 1 year ago.
  1. Is the odometer on with the key in the run position?
  2. With the key in the run position is the theft light off or flashing rapid?
  3. Will the headlights shine bright?
  4. Are you at home or stranded on the road or in a parking lot?
Customer: replied 1 year ago.
1.yes, but no numbers
3. Yes a stop on jersey turnpike
...when we try to start we hear a buzzing sound
Expert:  Chris (aka- Moose) replied 1 year ago.

1) No odometer is a good sign the PCM is not good or not getting all powers and ground

2) A rapid flashing theft light means the computer is in theft mode and it has disabled the vehicle

3) Should mean the battery voltage is good.

Give me a minute in the meantime search the vehicle for a paperclip, or short piece of wire.

Expert:  Chris (aka- Moose) replied 1 year ago.

Remove this relay under the dash.

Match this diagram with the holes under the relay.

Turn the key to the run position.

Briefly jump a wire from pin 30 to 87, the engine should crank.

Does it start though?

If not then a volt meter and possibly a diagnostic tool are needed to proceed, do you have either of those tools?

Customer: replied 1 year ago.
Is there a way to change the fuse that's there already?
Customer: replied 1 year ago.
The relay
Expert:  Chris (aka- Moose) replied 1 year ago.

The relay is likely not to blame like the fuse you asked about prior. I am wanting you to bypass the relay, ignition switch, and transmission range sensor. If it cranks but does not start this means its a theft system or PCM issue.

Customer: replied 1 year ago.
How do I bypass these?
Expert:  Chris (aka- Moose) replied 1 year ago.

You do exactly what I mentioned in the long reply with diagram files I posted 13 minutes ago.

Expert:  Chris (aka- Moose) replied 12 months ago.

Hello again Chris here,

I am contacting you because the post has not been closed or rated. We have 7 days to get a post rated before it times out. When a post times out, that means its no longer on my active list (if you reply I never know it.) You have already paid the fees to get this question answered, but it appears you're not pleased, or need more help.

Let me help some more. Is there anything else you feel I could offer so you would be pleased with my help. I have the option to call you if that would be better.

Thanks Chris
