tahoesoob Posted October 24, 2006 Share Posted October 24, 2006 Anyway i was driving home from my buddys house and i was going up a hill and all of a sudden i lost ALL power in my '86 ea82 wagon. I pulled over (it was dark and i had no flashlight) to see what i could find. I ended up caosting down the hill i was trying climb, i coasted down to the nearest street light to have a look, everything seemed fine. I have recently replaced my plugs, wires, cap, rotor, all filters, timming belt, and few few vacuum lines. I was having trouble with the secondaray on the the carb but never got around to fixing it. the car will idle but when you try to give it any gas it wil die. Can the coil be causing this? or does it sound fuel related? or possibly a vacuum leak. I am going to tow it back to my house tommorow and check it out. Any suggestions would be much appreciated! thanks. Link to comment Share on other sites More sharing options...
NoahDL88 Posted October 24, 2006 Share Posted October 24, 2006 I have recently replaced my plugs, wires, cap, rotor, all filters, timming belt, and few vacuum lines. I was having trouble with the secondary on the the carb but never got around to fixing it. the car will idle but when you try to give it any gas it wil die. Thats all the important stuff, sorry, trying to sort it out so its easier to read. It runs, so obviously your timing belts are intact. Also, you have fuel and spark, at least enough of each to make the car idle. Make sure that all your ignition connections are good and tight, make sure the screw on the rotor is also tight, don't think that could be an issue, but you never know. make sure that your plugs are gapped between .039 and .043, no more than .045 at the most. If you replaced your plugs with bosch, especially the plus 4's then get to the store, and put in the 1.49 dollar NGK cheapo copper plugs, this should solve your problem, if you don't have bosch plugs, then the issue may be elsewhere. Make sure you're not loosing fuel under the car where you put in the new filter, you may have a fuel leak. I'm out, next internet mechanic?

Flowmastered87GL Posted October 24, 2006 Share Posted October 24, 2006 Try leaving off the air filter top... my 86 GL died when I tried to drive it... when I moved across town I had to turn up the idle and leave the top off the air cleaner to help let the excess fuel evaporate... made it across town without flooding! Then I swapped out the carb. Fixed the problem. If you see a waterfall of fuel dumping into the carb when its running... that may be the issue as my 86 would die when I gave it gas.

GeneralDisorder Posted October 24, 2006 Share Posted October 24, 2006 Stock Hitachi carb I assume? Check to make sure the air filter isn't just full of oil.... The Hitachi floats like to stick partialy closed. I had one that did that as long as I owned it, after being rebuilt 7 times, and on two different cars. I threw it away in disgust. Being stranded randomely with a problem that dissapears as soon as you pop the top off the carb, and may not return for months..... for the record it's not cool.

tahoesoob Posted October 24, 2006 Author Share Posted October 24, 2006 Ok, i tried to drive it with the air filter off, still didnt work, it has the symptoms that its to lean. Also, i did use NGK plugs but a gapped them at about .45, maybe i should pull them and gap them at .40? im thinking the excessive gap may have ruined the marginal coil. I will check fuel pressure after work today, im thinking the fuel pump could be bad also..........i just changed the fuel filter to. Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted October 24, 2006 Share Posted October 24, 2006 ... i was driving home ... and i was going up a hill ... It lead me to Think in the EGR Valve... when you go Uphill, and EGR is Worn; some Oil can go inside the Intake or in the Carb, and shut off the Engine... Did you saw Oil in the Spakplugs? Also, check for a Broken Timin´ Belt... or a Broken Wire in the Main Link Fuses, the Black Box near the Battery... Good LucK! Link to comment Share on other sites More sharing options...
Frank B Posted October 24, 2006 Share Posted October 24, 2006 Start with the little things, spark and fuel. If it runs at all, it has spark, so check your carb. I had the same problem with an 86 ea82 carbed car and it was the float sticking. Remove the carb, take it apart and clean/rebuild it. Check the float height and by the specs in the rebuild kit. My vote is on the float. Link to comment Share on other sites More sharing options...

GeneralDisorder Posted October 25, 2006 Share Posted October 25, 2006 The carb fuel pumps are almost indestructible. I wouldn't suspect it. Rebuild the carb. Fuel pump pressure is only about 2-3 psi on the carbs. Probably one reason the pumps last so long. They are vibrating diaphram pumps, not the rotating vane style used by the fuel injection (the electric motors die on those sometimes). They don't have electric motors, just a couple electro-magnets, and some diaphrams. Virtually indestructible unless they rust out. GD Link to comment Share on other sites More sharing options...

beataru Posted October 26, 2006 Share Posted October 26, 2006 The carb fuel pumps are almost indestructible. GD Hehe Almost is the key word!!! They have died before... for no reason................................................... other than.. old age.......
