95' GST wont start. Need some help ASAP.

[ebailey95]

Hey all, my first post here, but have been lurking and searching for days on end about my problem.

I've owned the car for about 6months with little problems(master cylinder, battery)

some changes/mods:
93 GSX 6bolt swap
Evo 3 16g
hks BOV
evo 550cc injectors(I think thats the size )
Python alarm system
NEW battery


The problem was: I drove 1.5 miles to my girlfriends house perfect. The car started up perfect, no hesitation, cranked and fired just like norm. Now when I went to leave her house, I went to turn the key and NADA. I drove the car about 30-40miles previous to this in the same day with no problems.

I've found my situation to be quite perplexing. At first I had full power to everything beside being able to start. Radio powered, Python alarm system would beep when armed/unarmed, warning would sound when key in ignition, all lights etc. At that point in time I would try to start and hear the starter solenoid click and nothing after, almost like a dead battery. I tried jumping and nothing. after a few more tries and some investigation i still didn't have her running.

I walked home, searched more here, then went back thinking i might have found the problem. NOPE. I thought it may have been the starter relay because now when i turned the key I was getting a loud buzzing sound coming from the rear of the center console. I removed the radio, checked the starter relay and all seemed fine. I bridged the relay just to check and I didn't get the buzz, but I got the click and nothing.

One thing that happened previously was how I discovered my positive battery terminal was shorting on my strut tower brace across my engine bay. What fuses or relays could this have possibly blown? Ive checked all and haven't found anything bad.

I do hear a pump of some kind running when I turn the key to ON but not sure what it is, it's only come on a few times after waiting a few mins between tries.

My main question is: What would cause the buzzing? Is it the Starter relay? could the MPI relay do this? It sounds like the MFI/MPI may be the source but im not sure. Could it be the alarm system?

Again, I hear the solenoid click, but wont crank. I havent have the chance to play with the starter, but i have a feeling its not it because it started up PERFECT just 3min before i tried again. The buzzing inside also detours me from the starter being the problem.

Please, if anyone hase some suggestions or can help, I'm open to anything. Just wanna get this problem fix and get boostin again

My ground cable is a little frayed, but still makes contact with both the neg battery terminal and body. I moved the battery around and fixed the shorting problem, but still wont start.

Anyone? I've confirmed that the buzz is indeed coming from the MPI/MFI relay. What does this mean? what would cause this??

As of now I have no power to interior features like dome lights, radio etc
I also dont have the warning chime(like when you leave key in ignition) or dont have a security arming beep. The doors still lock/unlock by remote but no beeps.

anyone have any ideas? I cleaned and clamped down the terminals nice and tight and that didnt solve anything.

I really want my car running

UPDATE:

Ive now come to think the problem is in the wiring someplace, somewhere. Where should I start looking? I checked the ECU and everything seemed good (good caps, no fishy smell, no goop etc) I've checked all the wiring from the ECU and it all looked normal and I unplugged the alarm system with no luck. The battery terminals are clean and clamped down tight.

I wouldn't be as worried about this problem if I still had power to interior accessories. I don't have power to radio, inside lights. I DO however still have power windows, headlights, blinkers, wipers, locks etc.

Any new thoughts?

Check your main fuseable link, I had a similar thing happen to me when my main fuseable link went out. Even if it seems ok, try replacing it and see how the car responds. If you don't know which fuse it is I believe it is called what I have been calling it in your chilton.
