can you at least hear the starter relay and/or starter solenoid click when turning the key to start?
Ok, here is the wiring diagram.
Do you have someone to turn the key while you feel if it is the relay that is clicking?
If not, at least check those fuses.
So the relay doesn't click? Backup and test those fuses for voltage. Simply looking isn't good enough, you must check for voltage.
And check both sides of each fuse. The Maxi fuse 6 should be hot on both sides all the time. The crank fuse should be hot on both sides when the key is on start. the if all, ok, remove the starter relay and check the terminals in the socket, one should be hot all the time, that is from that maxi fuse and then one additional hot when the key is on start, that is from that crank fuse. If all ok, replace the relay. If not anything from the crank fuse, replace the neutral switch or at least test for voltage in and out of it with the key on start. Although now a days they call them a range sensor and are on the transmission.
No power to which terminal of the relay? You were supposed to be testing 2.
I going to bed now, I'll check in on you tomorrow morning about 10am or so.
Replace the starter relay.
Ok we are going to have to communicate better so we understand eachother.
Remove the starter relay and check the terminals in the socket, one should be hot all the time, that is from that maxi fuse and then one additional hot when the key is on start, that is from that crank fuse.
Let me know the results of these 2 tests. I know you probably already told me but tell me in a different way so I don't get confused.
No, stop. You are confusing me. Only answer the questions I asked. Then if I need to ask more I will.
I'm sorry to be blunt but this is going on for too long with misunderstanding.
Now, you are not suppose to be testing the relay, but the relay socket.
Forget about the fuse right now. Unless you are able to test the relay while it's in the socket but if that is how you are testing you have to let me know cause I am expecting the relay to be out.
Ok, but that isn't what I asked.
Are you testing with the relay in the socket or out?
I am starting to understand now. I think you may have to check the wire at the starter solenoid now when the key is on start, the purple wire.
Out? No, that's wrong. First of all, only 2 should be hot.
Plus, when you are testing do you have the key off, key on run or key on start?
So you are telling me with the starter relay out of it's socket, the socket has power to 3 different spots with the key off, key on run and key on start?
If yes, something is really truly messed up here. First of all, only 1 spot should be hot with the key off, then a second spot will only be hot when the key is turned to start and at no time should 3 spots be hot.
That just isn't correct. You are going to have to determine which it is to begin with that don't belong.
I might know a way to narrow that down. remove that Maxi fuse #6 and see which goes dead.
in the underhood fuse/relay center.
There isn't one what?
I will look it up.
I don't have that info. Isn't there a fuse #6, a 40a?
Wait, I see it's the same as the IGN A.
Here is a list of those underhood fuses,
No differenece? both still hot?
Do you still have jumper wires hooked up?
Nothing in the starter relay socket should be hot with that IGN A fuse removed.
You started off this post saying "Ran a wire instead of a fuse at the eng 1 plug" What did you mean by that? What were you running a wire to and why? Is this wire still hooked up?
Is this your vehicle or a customers?
I don't know what else to tell you except you are going to have to find out why that starter relay has voltage to it when it is not supposed to. I would assume you may have to just unbolt the fuse box and pull it out and look behind it or whatever and find out what is going on, such as if there is a shorted wire, a wire hooked up to something it isn't supposed to be hooked up to or what.
You have the wiring diagram, it should work like what the diagram shows. Anything else from that is wrong.
Unhook everything that is addon then retest.
