Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hi there. Welcome to our site!
Let's see if we can get that Saturn running on all six cylinders again.
First I need to know what we're dealing with here, so I need answers from you to a few questions:
Was the correct harness and ECM installed along with the 3.0 L engine?
Why were you replacing the coil pack?
What were you trying to fix?
Got it. Thanks.
Looking at the diagram, there is only the one ignition fuse that powers both coil packs, so I don't think the problem is there. Now, looking at how the coil packs are grounded, I do see that each has its own ground circuit (Black wire), so I think we should look at that ground connection. What do you say?
Please let me know if that solves the issue.
OK. Please give me a little time to mull this over. Be back in a bit...
I'm back. Pull the main relay and see if there's power at its terminals marked BATT (see graphic). Let me know what you find
Forgot the graphic. Here it is.
If the hazards and the horn work the problem with the main relay not having power to one of its terminals marked Batt is inside the fuse box it self. If the hazards and horn don't work either, then check the 30 amp maxi fuse marked IGN 0/3/CR. Let me know what you find.
OK. In that case there is an internal problem with the fuse box. I just can't see how the main relay socket would loose power if all you did was change the plugs and the coils. Are you sure the engine wasn't loosing power intermittently before?
For now, you can just put a jumper between the two BATT terminals, then plug in the main relay and see what happens.
Yep. First one should be ground (Black wire), second one should be power (Pink), the other three are used by the ECM.
Have you plugged in the scan tool after jumpering the main relay? Are you getting anything?
I mean, things like this don't happen just like that. There's got to be something someone is not telling. Can you ask the customer?
Ahhh... you know what? Could it be that somehow the anti-theft system got activated? Do you have a scan tool capable of communicating with the body control module? I mean, other than that I'm as stumped as you are.
Where is what located?
Mounted to the top of the glove box. Why are you concerned with its location? All I asked you was if you had a scan tool that could communicate with it because it controls the anti-theft module.
Man, I'm sorry, but this is getting much more complicated that I can handle. I'll opt out and let other experts try to help you. Please don't reply or the site will revert your request back to me.
Good luck to you.
