Crank no start - out of ideas

[Headlikeahole]

I'm desperate for help here guys

Situation - just got my 80 a month or so ago, I was trying to install a small timer relay for my abs light so I can pass inspection. While in the dash I was also checking and changing some of the lightbulbs. Connected the relay to one of the power sources, ground etc all seemed fine. I'm an idiot and didn't disconnect the battery and I think something short circuited.

When I turn the key I get no MIL, no battery light next to the voltage gauge, HVAC, dome light etc all work, engine cranks hard but doesn't start. Did some digging and thought the fusible link was my best bet.

Swapped the link. No change. Now I'm worried. Any help would be greatly appreciated.

If you give us the year that would help with trouble shooting.

Of course duh that's my bad.

Its a 94. I should add I tested the EFI fuses and everything seems fine. I tried testing the EFI relay but I'm not sure I'm doing it right. Not 100% sure what prongs I'm supposed to be testing and with my multimeter set to resistance 200 I seem to get 000s no matter which I test.

80 Series Engine Turns, but doesn't start up - MY 1994

Hi Everyone, I'm hoping there is some sort of checklist that's out there to what should be checked to ensure nothing is missed. So as the title says, the engine turns but doesn't start up. No check engine lights are on. The one odd thing is that the stereo no longer turns on (stock stereo)...

Thanks for the help. I've read through those and I was leaning toward EFI relay being the cause however my charge light still doesn't come on with ignition on. Which is suppose to be a sign of faulty fusible link which I just replaced.

Hoping it's not a short that busted the new link.

First thing would be to remove whatever you installed and return to an unmolested configuration.
Test links/fuses with a meter, not your eyeballs.
