i have a 86 2.5L iron duke, it has a hard time starting up and has a fluttering idle. it has no power when trying to accelerate and sometimes dies on acceleration. ive just done a ton of work to it, and the timming is correct. the only thing i havent touched is the injector system. do you think i have a bad injector or fuel pressure regulator? the car was sitting for five years and ive been trying to revive it, nothing has been going right so far
Often times a bad fuel pump actually turns out to be a crumbling 2" rubber hose that connects the fuel pump to the fuel line in the tank. Signs of this are the ability to maintain an idle ( barely at best ) and stumbling upon accelleration

ya i did replace the old gas with new gas that was one of the first things i did. as i said ive replaced everything to do with the fuel system with an exception of the injector and fuel pressure regulator, i did check my fuel pressure today it was at 12 psi. so i moved on to the injector, so i pulled the injector and i was surprised to find little metal shavings were the injector sits in, then i took the fuel pressure regulator off and there was little metal savings in there to. what is this a sign of?

You say the car sat 5 years. The metal is shiny. Is the metal magnetic? The fuel lines, filter, fittings, etc are mild steel and magnetic. The TBI is aluminum and non-magnetic. Would tell you better where it came from.
Now earlier you said you have replaced everything in the fuel system except the injector and FPR. Now you say you have not had the fuel pump out?

yes this is true, i havent had the fuel pump out, also doesnt the fuel filter have a filter on it? i will check to see if those shavings were magnetic
There is a filter almost everywhere in the system. The fuel pump has a strainer. It's a fabric like material. It lasts a long time but needs to be replaced whenever you service the fuel pump. Next in line is the fuel filter. Make sure it's installed with the arrow pointing in the direction of flow (away from the tank, towards engine). Then the fuel injector itself has little screens to catch even the finest material. Since you found metal inside the TBI on the injector screen, I would replace the fuel filter and clean the lines from the filter to the TBI plus the TBI itself. You might consider a TBI rebuild kit. Those pieces of metal could have held the FPR open and caused a rich condition.

when you take filter off tap inlet on2x4(or what ever)a lot of shiny stuff here tells you for certain,,metal mining is taking place in your tank with out your permission for mineral rights.. all the hoses can leak be split or there can be hole in line , use injector hose..check hose to vapor tank and tube,,,,just in case now is time to pb blaster or liquid wrench the 2 tank T-bolts for ease of removal later
