although I've done several min idle adjustment on my 85 using the gm fsm I have....I read a couple of threads indicating you should disconnect the distributor wire while doing this....seems like this would make a huge difference in setting the idles peed....anybody know something...

absolutely!!!! he the man:happyanim:

seems to me there was something in the fsm about not getting 12.....i'll take a peek at half time....i'm assuming you have one...if not, you'll need it eventually...factory gm manual..:beer

my 85 acted similar...didn't get the fuel pump connectors on good enough...wouldn't maintain fuel pressure...have you tested your fuel pressure and does it hold.. ko eo...?:w

end of this thread....pump didn't always turn on because I wasn't aware of the 10 second delay...followed the gm fsm to the bitter end...last box/ bottom of the page...loose rubber connector on the fuel pump....car now runs like a champ...:happyanim:

you might be right.....had the war dept turn the key on so I could quickly pinch the fuel pressure line...held pressure until I released.....going right back into the tank....considering the tries at fixing the old sending unit..3..1 fuel pump exchange , i;ve gotten pretting good at pulling the...

I have the gm manual...all thats left is to check injectors/cold start....since this happened so suddenly, just don't think an injector could leak that bad. pressure drop with return line pinched eliminates the fpr...I'm going to pull the fuel pump out and check it out. I didn't pinch the...

got around to pinching return fuel line ....pressure goes quickly to38...then 20, then 0 at the click of the relay...fsm indicates bad injector/cold start valve....that would have to be some leak to make the pressure drop that fast...i'm thinking has to be the fuel pump...if there's a check...

ok...getting wierder....now with key on...pressure runs up to 40 but quickly drops to 0 with a distict click from the fuel pump relay....that's new too....???? also, no strored codes anymore....:ugh

bought it from ecklers...probably a piece of crap....i'll get a better one if that's the problem....still don't see why o pressure with key...should be some....the minute you jump it the pressure comes up...:confused

pumps only 2 months.....comes up pretty quickly when I jump it..goes to maybe 30 and quickly drops to 20

weird one....was going to tear down the engine on my 85 and rebuild...decided to take one last run....car started/idled/ but wouldnt go.....threw a code 34....maf....did some diagnostics couldn't get the maf wire to glow with test leads...determined burn off probably bad....BUT....also threw...

welcome to the forum.....lots of good advice here....start with this....buy a factory manual GM.. then....remove, clean your throttle body...install a new iac....then set the idle and tps...assuming your plugs are good, should be running right. don''t be fooled, the ecm will compensate if you...

just a shot in the dark....lock and unlock your door.....happened to me....don't know why..just fixed it...:happyanim:

going around the circuit the 2nd time, found power to both wires to the spare tire light....per fsm, i think one should , not both with lights off....had disconnected bulb before....wasn't aware tested 12v in both sockets..cut plug out...both ends of wires to spare tire light test 12...
