Ok people, somebody help please...

Car: Ae86
Engine: beams
Computer: Adaptronic

Problem:
After sitting in the garage for a month or so I decided to start it just to keep it ticking over.
After flicking the switch that kills the fuel pumps, I turned on the ignition.
Lights lit up, fuel pumps kicked in, all good.
Cranked her over and it started no problems.
After idling for about 5 seconds it just died. I turned the key again and it started cranking but never came to life.
I turned the key all the way back and then back to ignition and noticed that the fuel pumps weren't turning on.
Straight away I thought that the kill switch for the pumps was faulty so I removed it and joined the two wires together. Back to ignition and still no pumps.
Then I checked all the fuses. All good.
Checked the relays. All good.
Next thing I thought was that the fuel pumps have shat themselves, so I gave the external one power from a battery and it buzzed. Removed the fuel tank and checked the internal and that buzzed too.
I had a friend come past and play with the wiring from the fuel pump relays, and made the pumps turn on when the ignition is on BUT if the key was turned to the ignition and left there the pumps just stayed on which isn't what used to happen. It used to prime itself and then they (fuel pumps) would turn off until you started the car.
Anyway even with the pumps wired in this way that they stayed on, the car doesn't want to start.
I am not very electrically savvy, in fact I hate electrics and never touch em, but something tells me that there might be something wrong with the computer or some shit.

So yea. If you have had a problem like this or know what the problem might be please let me know before I take it to somebody that does.

Thanks in advance

Check you have spark..

What lights are on your adaptronic when you turn the ignition on.

i would be checking everything electrical..... as in all the relays that are hooked up to the computer(including the wires that are hooked upto the bottom of the relays and the fuses if you have fuses in your relays) i have had that problem before.... Matt has the right idea, check that the lights on your adaptronic are are all lit up, do the obvious stuff first :). My adaptronic does as yours used to, primer for about 3 seconds before you start it

I've had this happen before. I can basically guarantee you that the adapt isn't on. Check the lights are on on the ecu when the ignition is on. In my version all three lights are on not sure with yours but at least one should be on.
check the plugs on the adapt. check the earth to the adapt and if you still get no power to it I would be contacting the adapt guys. I have a feeling their is a fuse inside the ecu.....don't take that for gospel though last time I had mine apart was like 2 years ago in a moving car lol

Thanks guys
Just checked the ecu and when i turn the ignition on no lights light up.
I checked the plugs going into it and they are all good.
I couldnt see any relays or fuses that are connected to it and chased the wiring back all the way to the individual coils.
I also pulled the ecu apart and there are no fuses inside it.
Where to from here?
I might give the Adaptronic guys a buzz and ask what they reckon.
Once again thanks for the advice.

Ok
Just checked the Adaptronic site and their forums and there is a whole checklist to go through to determine the problem.
I'll give that a go and let you know how I went.
Cheers
