I just got my 90 GS home from California on Thursday, it hasn't run since before I moved to Arkansas, still cranking but won't start and I have no power to the windows and sunroof, my head unit also flickers when I try to turn it on. I've been told it may be the ignition switch. Anybody have any idea what to do next, I'm at a dead stop. And I just installed my coilovers and header today, I'm ready to ride!

Check the fuses for the windows first. Trace back the power and make sure you have power at each step in the chain. Just to be sure, you hear the fuel pump when you turn the key to the on position?

So I'm getting power to the fuel pump, a friend of mine said it would likely be a ground wire somewhere in the harness, anybody got a diagram, because I can't find anything yet.

Getting fuel, air intake is good, but no spark yet. Plugs, wires, distributor is new, belt is good, fuel filter is new, I'm out of guesses for now.

new part can be bad .... your playing a guessing game called swaptronics or tryonostics take the car into a shop shooting the parts cannon is not working for u

Thanks for the vote of confidence, however, I'm not trying to play guessing games, I'm trying to narrow down the cause of the problem. And just because I can afford new parts, doesn't mean that I'm playing " swaptronics" or " tryonostics". I just want my car running like everybody else. 👍

sorry was not trying to come off as a douche bag ........ but you are narrowing down the search by replacing parts that possible could be the problem ..... you need to test parts to narrow it down ...... buy a hayens manuel for the car ...... ive seen it to many times people start swaping parts and the new parts burn them because new does not equal good

I get where you are coming from, and

I get where you are coming from, and thank you for the clarification on your position, it's just driving me crazy because I'm trying to get it running again and having to work 6 days a week for 12 hours a day puts a strain on my time. Thanks bro 🙏

you need to get a wire diagram thats why i suggested the haynes manuel because they are in there ....... if i was in your position i would start with powers and grounds and signal wires right at the distributor it cuts the system right in half if all is good at the distributor then the problem is either the coil in the distributor or plugs or spark plugs if your not getting power or ground to the distributor then its a wiring or fuse problem but if your getting powers and grounds but no signal then its the ignition switch

Use a multimeter to check the battery to make sure you have 12 volts if you haven't already. I'm not sure how recent the picture of the engine bay is, but the ground terminal looks rusty/corroded. I would also use a wire brush or sandpaper to clean the battery posts and the inside of the terminal connectors. Make sure that the terminal connectors aren't cracked or broken and that they will tighten down enough so they they don't move. On a lot of cars, bad battery grounds cause strange electronic problems. Some things will work sometimes and other times they won't or they will only work partially.

Once you've confirmed the battery and the connections to it are good, follow the instructions on Meltman's article for Advanced Ignition Troubleshooting . You will need to look up the resistance specifications for your car. I think Melt's article is for a G3, a G2 should be very similar.

If that checks out, I would probably make sure that the new distributor was installed properly. Hope this helps. Good luck.
