I have just completed a rhd swap as well as a sr engine trans the hole shebang. Tester I was finishing up by installing my gauges and when I got to he greddy oil pres gauge I believe I wired it incorrectly to the ignition. Now the car won't start and wha I mean by that is there is no power. The battery is good all of the ignition and acc relays are good. I removed the gauge from the wiring and tried to start the car and still nothing. I also have a apexi auto timer but it came with a plug and play harness. I also replaced the fuse link on the positive battery terminal. So what do you think?

Check the timer harness. The power pin on mine was going to a blank pin on the ignition and wouldn't let anything get power. Voltmeter will make things easy.

It's wired correctly there is no voltage to the ignition switch. When I remove the apexi timer still no start. It seems that something between the battery and the switch is stopping the car from start up.

Sounds like you blew a fuse. Did you try wiring the gauge with the batt still connected?

Check the kick panel fuses.

I did wire the gauge with batt still hooked up. All of the fuses are good. Thanks for the help. I have been working in this car for 3 months now and I had here running perfect before this gauge install.

Where is the fuse that's attached to the postreminal cause I have a red box I don't see a fuse? Kind of a stupid question

i always hook the gauges up to the stereo wires since it cant keep u from starting the car if it blows and a fusable link wouldnt be a bad idea

That's funnier than the problems I'm having!
Let me guess you have no suggestions either.
Thanks for your intelligent input!

Well after some more trouble shooting I found that my 10 gauge 12v live wire that goes to my ignition switch from the ignition relay 1 was compromised. I replaced the wire and it works like a charm. If you ever have any ignition issues I would use this link as a basis to start working from.

Thanks guys for the help let me know if there is anything I can help with.
