Well you just saved me. I replaced the vatts with the bypass module. Ran for years. Than let it sit for years after it stopped running. I never came across this video after doing tons of research. I just did it and it started again. Huge props bro🤘👍
I'd image the car would never start if you pulled that fuse. The fuse that says "theft" is for the theft deterrent system.. basically it will keep your horn from honking if you take it out.
I have a 91 c4 and having the intermittent no start. New starter, have the vats bypass. No one can figure it out. I'm leaning to the neutral safety switch by need to know how to bypass it
depends on what "better" is. Yes you can replace it, and it would have fixed my issue if I replaced it. I didn't replace it because the VATS still won't let the car run if it's active. I can easily hear the fuel pump running or not, but I can't do that with the relay. For me it was "better" to bypass the relay and leave the other part of VATS alone.
@@JerrSpud Not running yet Hopefully once the ignition switch, new key, and I even order bypass that goes under steering comes in. Hopefully that will work and get my car started again. For now it cranks but doesn’t fire So I’m thinking it’s the computer with the anti theft that’s holding my car from starting. I have gas coming to injectors I have spark Any ideas what to do?
Hello, I need some help. I bought a 1988 Corvette convertible manual Trans that has been sitting outside for a while, not running. I found Mouse nests under dash top near gray VATs module. No wires chewed that I can spot. I have no way to speak with a prior owner. The car was rigged with a separate wire going to starter solenoid so it could be touched to battery and would turn over. I turned the ignition on with the key, dash lights came on then I turned motor over with jump wire. I got no spark and no sound from injectors. I unrigged jump wire, I bought all 15 resistors and tried them all 4 minutes apart to bypass VATS. I have the clutch safety switch bypassed and the Vats start relay bypassed. Still nothing when I turn the key. I have cleaned all grounds to the frame under the hood. Unplugged and cleaned every connector under the passenger side dash. I replaced Plugs, wires, dist cap, rotor, Ign control module. I have some fuses with no power going in to them: HTD MIR, Inst-LPS, FR or FP( I cant read it but it is on the bottom row far right). In my convenience center, I have no power to the fuse labled: Cinj/clu. Can you please give me an idea of what to try next?
Hi, hopefully you can help? I just got 1990 C4, but the owner lost the key. I got the new key at the Dealership with no chip and bought a bypass for the vats. But unfortunately I forgot to disconnect the battery first and my dashboard went out. Do you know that fuse or fusible link is??
@@JerrSpud before I installed the bypass the dashboard was working properly. After I installed the bypass the dashboard would not turn on? Thank you for responding.
If you watch the entire video, you'll see that wouldn't start at the beginning and it ran by the end. Sometimes it would start just fine and sometimes it wouldn't. All these steps are how you go about troubleshooting the one of three problems it can be.
Ok so not the battery starter neutral saftey or relay. Only thing left is vats and tumbler? Car ran fine. Cranked one day then when turn key nothing. Thanks
@@robertjenkins7372 Bad cylinder or bad vats key if VATS issue. If security light doesn't go away when key is turned on most likely a VATS issue. If Security light goes on and then goes away the issue is something other than the VATS.
