The key with a slash it referring to your SKIM key or SKIM module.. Do you know what codes you have?

Customer: replied 1 year ago.
No I don't
Also I notice when I try to start the car I hear a noise in one relay
(ASD) I replace but still making noise
Expert:  Brad replied 1 year ago.

The first step in repairing this issue is to see what codes are in the PCM and SKIM using a scantool.. It could be a bad module or wires bad in the door jam, but without the codes you will be guessing as to what is wrong..

We try to scan to read troubles codes with two different scanning tools and on both said error scanning turn off switch for 10 second and try again. We try but always said the same.

Have you tried disconnecting the crankshaft sensor in the bellhousing?

Customer: replied 1 year ago.
I replaced
Put a new one
Expert:  Brad replied 1 year ago.

OK just making sure because it says you replace the camshaft sensor which is a different sensor.. At this point without a scantool to see which modules are on the BUS you can test for 5v on the orange wire at the TPS or MSP with key on and it should have 5v, if not the PCM is dead..

Hello and welcome. Different expert here. Does anyone I'm starting fluid? Have you checked engine compression? I'm going to send over an offer with my phone number. If you'd like to talk on the phone please except my offer and call me. I do work until late tonight but will be available to chat after work. Please leave me a message if I don't answer.
