Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

Have you checked the wiring leading from the fuse at the fuse panel for any shorts?I have seen issues in the past before where this wiring can short out and cause this fault here.

Let me know,thanks Pete.

I done an electrical test with my meter and it says it's fine
Expert:  Pete replied 12 months ago.

O.k.,even though the meter says it is fine inspect the wiring harness manually and check and see if any shorts to ground are found or any shorts to another harness is found to be at fault needing repaired or replaced.I have found this as the most common cause for this fault here and in some cases the short is at the fuse panel itself needing repaired or replaced.If you check all of this and find it to be o.k. let me know so we can continue.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete

I apologize for the delay.

After looking through my diagram info on this here unfortunately I do not show the diagram with the engine you have myself but others here may have this info.

I will open your question up for others here to see if someone else can assist further on this as there may be others here that may have more info on what to check or do with this issue.I hope you can get this resolved with ease.No need to reply to my last post here unless it is a last resort as it will keep your question locked to me and others will not be able to view it.If you feel you want to continue to work with me on this feel free to reply at any time but keep in mind in some cases it can be difficult to fully diagnose or help repair this without seeing your vehicle.

Thanks Pete

Does the fuse blow immediately or does it blow after you try to start the vehicle?

Customer: replied 12 months ago.
It blows as soon as I turn the ignition on before I try to start it
