No power to cluster, no headlights, no dome lights, no radio power, nothing at all when the key is turned to run. When turned to start, the newly installed starter cranks the motor, I get spark, but it will not stay running. The fuel pump does not power on when the key is turned forward as it used to. Seems the fuel pump along with all other electronics are not working for some reason.
Update #1 When I connect my test light to the negative terminal of my battery, and then touch the probe to the firewall, it lights up.
Update #2 With the ground wire to the battery disconnected, I have 12v on my ground cable.
There is no power anywhere in the vehicle as stated, so no check engine light.
The battery is sitting at 12.3v
I need you to be able to go back and forth with me quickly so I can perform your tests and get back to you within minutes. The van is in my driveway and I am ready to fix it. If you can reply quickly so I am not waiting all day, I will continue. Please confirm.
I see that you are more than credible. I will wait for you dependant upon how long I must wait. I am in MI, EST, it is 2:08PM here, what time must I wait till? Also, please be very descriptive with me and let me know what tests I can perform in the meantime to help you diagnose the issue.
The 140 amp is the alternator fuse. I am bowling now and will not be home and ready to work on the van until tomorrow. Is that ok?
Ok, the 140 alternator fuse has power. Am I supposed to pop the plastic piece off of the other fuses in there so I can check for power on them?
So what is the proper way? If I remove the fuse, all it tells me is that there is power going to the fuse, but is does not tell me if the fuse is good. How do I test these fuses while they are plugged in? They are all square fuses, not spade fuses.
I don't think you understood me here:

I am able to pop the clear plastic piece off and then use my test light to see if I get power. I will go test them all, and then I will report back.
Testing now, stand by.
Ok, all 14 fuses have power at all times.
Funny thing I just noticed. They all had power even with my battery ground cable disconnected. Another thing that is weird.... When I connect my test light to the battery negative post, and check for power, I have 12v on the metal grill of the van.
Checking now. Again, the engine block and grille of the van have 12v, and they should not right? I will check the interior fuses and report back.
All fuses have power, both under the hood and inside the vehicle. The battery now has the negative cable hooked back up as well.
Not a single light anywhere, headlights, dome lights, radio, dash cluster, the buzzer does not buzz like it used to when the key was inserted, nothing at all. But the starter will crank when I turn the key, yet still no lights. The engine block still has 12v with the key on and off.
Can you help me locate them please? I am not familiar with this vehicle, it is my grandfathers.
Please do not lose your patience with me, but how are you wanting me to conduct this test? Do you want me to disconnect the sensors and check a certain pin on them with the key turned forward? Or dig my probe into the wire with it connected? Sorry, excuse my ignorance.
Both connections have 5v or slightly more at the harness on 2 of the 3 pins.
Not sure if my last response went through, I have 5v on both harnesses in 2 of 3 pins like you said. What next?
There is no power to any light, under the hood, the glovebox, anything, no power to them. Also, when the key is turned forward, I can not hear the fuel pump working like it used to.
I was wondering about the fuse box under the hood. Remember, this all happened due to the jumper cables being hooked up backward. I will try to follow what you said and test the circuit.
Jason,EVERY SINGLE TIME I have seen this issue caused by jumper cables being hooked up backwards, it is due to a blown fuse or fusible link. Hands down.
So you think we are going to be able to fix it! I hope so my friend!
They all have power at all times. I only have one ground cable going to the battery is that right? Then a cable that comes from the harness and grounds to the firewall. Both cables going into the fuse box have power on them at all times.
the cable you circled is the one that connects to the firewall.
the harnesses may be causing the problem, when they were unplugged, i had no power on the fuse box inside the vehicle, then i plugged the first one back in, i think the map, not sure, and still no power to the fuses inside, then i plugged in the other, maybe the tps, then i had power all the sudden.
Van is running, but the radio goes out when the headlights are turned on sometimes, and the lights seem dim. The dash goes in and out also. Gauges work sometimes, not sure if loose connection, short, or battery problem.
I replaced the old ground wire and made sure the new one had a good connection.
13-14v so alternator is working. Still when headlights are turned on and off radio dies, lights dim and sometime gauges dont work.
