Hey guys. Haven't posted here much but the guys at ZDriver are becoming retarded in trying to help me with my problem, so I am posting it here hoping that someone can help.
I started the Z31 ECU Upgrade to my 1982 280zxt back before Christmas, but with snow and a lack of a garage I was unable to complete it until this past weekend when it started warming back up. I double checked all of the steps from the tutorial, switched the 108 wire so it would control the Fuel Pump, added the 84 disk to my disty, and have an 84 Turbo ECU and MAF.
The car ran perfectly fine before the swap, but now it is acting weird. If I go out in the morning it will fire up fine, idle fine, and revv with no problems. But then, after a bit, it will just stutter and die. Sometimes it will start back up no problem, but sometimes it will not want to start back up for the rest of the day. I double-checked the wiring and everything is correct and secure.
Today, my friend came over and we went to work, adding a fuel stabilizer thinking the gas was just impure and when under a load was fouling up the plugs. It fired up easily after dying, but then died the same after about 5 minutes, and won't start back up. I have another project car that we took the adjustable Fuel Pressure Regulator off of, and put it on thinking there was too much fuel and it was blocking the spark. No difference. I then pulled off the fuel lines we had just installed and found that they were all still dry, both sides of the FPR, showing that there was no fuel entering the system. We are both out of ideas, so I am looking for help.
Like I said, if it sits for a while it will fire right up, but then dies within minutes of fuel deprivation. Also, after we installed the aftermarket FPR to be able to tune the Fuel Pressure, when we went to start up we heard two pops, one from the intake filter and one from the wastegate, both put up a little cloud of smoke.
Any suggestions will be gladly taken into consideration. Just need it running...
