Hello welcome to just answer I am master tech and will be able to assist you.

can you tell me what prior work has been done .

Customer: replied 12 months ago.

Nothing has been done so far..vehicle had been sitting for 6 months or so..just checked underhood and dash fuses

Customer: replied 12 months ago.

Vehicle was running fine when parked..battery was dead upon arrival also

Expert:  MASTER TECH replied 12 months ago.

ok when you turn the key on does the check engine light go off or stay on ?

Customer: replied 12 months ago.

Stays on...no immobilizer light at all tho

Expert:  MASTER TECH replied 12 months ago.

ok lets check the alternator main pivot bolt ( 14mm) see if it's loose

no alternator work or timing belt ?

Customer: replied 12 months ago.

Ill check that bolt and get back with you. Can you tell me what made you ask me to check this?

Again, no work done, car was parked 6 months or so ago with a slipping transmission problem. Vehicle ran great. Vehicle towed to us this week.

Expert:  MASTER TECH replied 12 months ago.

their is a known issue with these bolts been loose and over time they will short the pcm if this is left loose.

Customer: replied 12 months ago.

Wow ok interesting..it was tight tho..

immobilizer light not coming on is definitely concerning me....ecm is ground main relay 1 and 2 when key turned on, so Ecu seems happy..even did immobilizer brake code to try to get vehicle to start

Expert:  MASTER TECH replied 12 months ago.

ok let give me a bit I will look up some info for this.

Expert:  MASTER TECH replied 12 months ago.

here is some diag info to get you started

Customer: replied 12 months ago.

you sent me mil circuit diagnostics? nowhere in there does it mention anything about the immobilizer. the only real help i got from this is i also realized the oil pressure light isnt coming on during bulb test either. All other cluster bulbs seem to work other than the oil pressure and immobilizer key light.

Expert:  MASTER TECH replied 12 months ago.

ok this was for a no start and no codes stored diag.

I will look up imobi info also.

but to confirm the Key icon is not on at all correct

Expert:  MASTER TECH replied 12 months ago.
