Okay here's the deal. I have a stock 1987 GN with an old stage three chip in it thats been running fine for about a year.Until now (Of course). It all started when i stopped at a gas station by my work to get a soda. the car had about five gallons of gas in it when i shut it off and went into the store.when i got back in and tried to crank her up.It would only start for about two seconds and cut off(almost as like if it were lacking fuel).The car wouldnt start at all after i towed it home. I immediately started troubleshooting the car. First i checked all the fuses (fuel pump, ignition, etc, etc). Then i checked the relay, and replaced it just in case. Then i took the fuel pump out from the gas tank and hooked it up to a battery to see if it was pumping fuel( The pump seemed to have plenty of pressure to push fuel through.)I also checked for any shorts in the wiring from the ignition switch to the fuel pump. It tested out AOK.I also checked the ignition system to make sure it was getting enough spark to all the plugs and it seemed just fine). I then replaced the mod chip back to the stock chip just in case their would be any problems in that area.and of course it still wont run. the only thing i can even possibly think it might be is my fuel injectors may be clogged or something with my oil pressure indicator switch.To be honest im really used to working on old carb driven vehicles.So please please please let me know if you have any idea at all with whats going on with my GN. And/or what i can do to fix it.
Thanks: Nick........

check fuel pressure at the fuel rail with a pressure gauge and use a noid light to see if the injectors are firing.
