I feel like an idiot here. I changed the battery and the contacts, and I get nothing. I will say I did not surface the battery terminals. Is that actually necessary? Anyways, I feel like I'm wasting space here, but I really need to get this car going.

proably put the battery in backwards.

Double check that the Negitive terminal of the battery is next to the headlight, and the positive terminal of the battery is at the shock tower.

Remember that the ground lead is also Black/yellow at the battery.

ok, thanks man!

Chances are you will have to replace the 80a or 100a fuse under the hood too. It blew on mine when i connected the battery wrong

SoontobeLS1'd

Okay, I got everything in its proper order and the 80A fuse is replaced. The engine turns over and the headlights, info center, and the gauage cluster light up. However, the dome lights and the CD player do not turn on. Possible other fuse blown? If so, which one? Now, I cannot get the engine to start. It rotates, that is it. I thought it was flooded so I let it dry out by taking out the spark plugs for a few days and cranking it once for about 10 seconds. I got everything back in and no luck. I did the EGI fuse thing a couple of times, nothing. Here is the question. There is a broken, metal vacuum line behind the alternator. It is welded to a fuel line and is connected to the dynamic chamber by rubber hose. Could this broken line be keeping my motor from starting?

You need to see if your ECU is coming online, you probably nuked that when you reversed the polarity on your battery. And you can probably kiss your stereo goodbye too, but you need to check all the fuses in the drivers side foot well, there are some there that control the engine.

And you are putting an LS-1 in your rotary?

exactly my thoughts. Your stero fuse may be blown, but the stero its self is probably fine. Just go under the drivers side and look under the dash and just start pulling and looking at fuses. And my personal guess is your ecu fried.

i thought it might be as well. yes i am putting a LS1 in my car. i didnt want to take the 13b out so soon, but it looks like im retiring it. nothing against the rotary, love it to death. but it cant give me what i want with my budget and space. thanks for your help, guys. ill probably do some looking around under there to get the interior going again. as for the motor, it'll be up for sale shortly along with other parts i don't need anymore.

Ha ha, that was my first thought too- having trouble installing a battery, and wants to throw an LS1 in there...OK, enough flaming...

You need to check your 5 volt reference output from the ECU. This is most easily accomplished by accessing the boost sensor location's wiring. Check for 5 volts DC at the brown/white wire with the key on. If you got it, good. If you don't, change the ECU...

SoontobeLS1'd

in my own defense, the contacts were mismarked...red on neg, black on pos. thanks for the info.

Kory_yahi

isn't that reverse polar?

I really wasnt trying to flame.. Sorry..

At least LS1 didn't run his car into a wall

how could i when it wont even start??

Just to let you know, the two fuses you need to check are the bottom two, on the lower-left of your in-car fuse box, that's in the back left corner if the driver foot well. Those should get your stereo/interior back online.

I had a strange thing happen with my stereo once. .I blew the fuse that gave it 12V switched (I was playing, nothing serious ), and for some reason (completely unknown to me), it was causing a "Pulsed" 12V through the rest of the interior system. It would be a 1 Second on, one second off kinda thing. It was in everything, dash lights, ECU voltage, stereo, etc. Of course, the ECU can't operate like that, so try getting that back online, and it make clear your problem up.

SoontobeLS1'd

cool, thanks dude!

FYI, thats not a function of it being rotary or V8.

And Wayne is a punk...

SoontobeLS1'd

it not being able to start? i know, haha, it's a result of a series of nightmares stemming from one small problem.

WAYNE88N/A

Did you figure out if you got the 5v yet?

Rat, that's insubordination- I refuse to be called a punk by someone so much junior to me (in both age and wisdom)

SoontobeLS1'd

i haven't checked yet. i will update when i do.

So, I don't mean to jack your thread here, but I think I f'd up royally. I have a 91 NA original almost everything. After a couple years of it sitting doing a whole lot of nothing other than starting it to make sure I kept it from seizing I decided to plug in the charger and try and get the battery charged up. I plugged in the charger backwards, on high 12V current for about 45 minutes and now I get nothing for electrical, no dash, no brakes... nothing. All fuses are fine from what I can tell including the big 100A in the main fuse block, and I didn't try to start it, I simply key on'd it to see if I got anything interior when it was charging reversed. The battery was disconnected after that and it has been sitting for a couple weeks since this incident.

ECU screwed on this one? I won't be able to test it for a little bit, but if you can tell me what to test on the ECU I would appreciate it.

Scratch that. I pulled the main fuse, plugged it back in and went to test the voltage to the fuse and BAM!!! headlights and full lights with full power. Apparently I got SUPER lucky on this and no damage done to the car as the reversed polarity never made it past the main fuse. Now its time to get some maintenance done and get that rotary screaming again.
