i have a similar problem.... i replaced my UIM and LIM and removed rats nest and now have 3 vac lines ....car will not start ever since ....and installed aux ports 5/6th if that would matter ....list of things checked

TPS is set correctly ....
checked for vac leaks ...and saw none
all vac lines are caped ....
OMP on UIM are removed but ones on block are not
removed ACV
TB mod
car acts like its not getting fuel ....


but if its push started by a second car it runs..... NO idle
so any help or pics of car w/out rats nest or ACV would help .....and i say all this b/c it is a close problem with a similar answer....and those would be things to look at for everyone also .....sorry if i thread jacked ...any help would be nice tho thanks please post pics !!

 

Fuel Pressure Regulator

 

Brett(87 FC GX) have you figure it out yet. im am having the same problem.

 

no dude i havent im sorry. my injectors are the next thing im going to check:P

other than that the only problem is it wont go below 3000. but it goes above! its so CONFUSING

 

its NOT my injectors, its NOT my idle screw, its NOT my spark plugs. AND its NOT the yellow connector, its already been jumped

WHY THE !@$@ WONT IT REV *UNDER* 3000???!?!?!? :S

 

Im havin some crazy problems also. I made a topic no one seems to help yet. Hope one of you figure this out.

 

have you restabbed your CAS or are you just adjusting it by turning it?

 

i tried that too. Im going to try taking off the upper intake manifold and double check all the hose again. did you tried the MAF yet. I know its not a Fuel Problem or Timming as of now. Check the soldnoid on the Vac rack. it felt to me like its not getting enough air into the rotor. So try the MAF as of now. It might be that the Flap on the MAF is not opening like it suppose too. thats just what i think. But ill check my again fri after i got off school. Im still in high school so i dont have much time to work on it.

 

I don't know...

Would a clogged exhaust cause this? Check the fuel solenoid resistor under the air box per FSM (I'm *not* talking about the AFM).

Search "pictures sensors reference" with my name under advanced search. I'm working on organizing it better, but you'll see some pictures there. BTW, FSM links in my sig.

 

does anyone know where in winnipeg i could get a new MAF

 

Its a vac leak. 100% sure. Thats what N/As do when you have a vac leak. Dont ask me how I know.

Trust me, check everywhere for a leak.

 

alright thanks. lol well i have pretty much every tube plugged or there is a hose on it.

 

Its probably bad practice to assume everything is plugged in correctly if its not working.

Read your PMs

 

yeah lol good theory. but this car ran a couple months ago and they guy who i boiught it from only pulled off a few hoses.

 

Its the AFM. Just got mine running today. I barrow it from Tek88 and it works. ill be sending it back to him when i go to the junk yard.

 

oh man. this guy thinks it might be my gaskets, rings causeing air leaks. it sounds like a TONNE OF WORK

 

which gasket is the guy talking about.

 

I may be the stupid of the classroom, but mine does the same : starts, revs to CSassist, then dies. I was afraid I've damaged my AFM when, trying to remove it for the first time thinkin myslef knowledgeable enough (how pretentious!), so when unscrewed the AFM's own plug... instead of removing the harness plug... then heard some strange noises, scared me and screwed it back. I've opened it just maybe 2 or 3 milimeters but I think it was not meant to be open at all!
Some can confirm it's hard links inside (so I've broken it) or are there some soft wires so my problem is not from there?
I'll put it appart anyway and check the res with my DMM.

 

No way to keep the engine runing with gas. So my AFM... Another ******* Mistake...
