ok i finally got my 85 running right. found some vacume hose disconnected with screws in them. rearranged a few hoses but still have 1 that i cant find a home for anyone know where i can find a vew of vacume hoses? :cry:

Get yourself a service manual for your Elky, it's from Chilton, I got mine from O'Reilly's. This manual is very comprehensive and has a chapter on Emission controls and vacuum line diagrams among other very useful stuff.

It's right on the sticker on the fan shroud.

b4black,
Visited your website, again. It's been a while since I visited. Neat website. Great info. A must for every "performance" Buick fan.

Robert posted this in another forum, it may help you out! Vacuum line diagram (http://elcaminocentral.com/articles/vac/86vacuum.html) :cool:

You just described exactly what my old '75 Chevy Vega did a few months back. Turned out that the fuel pump was bad, it would run for a while until it got so hot that the internals would expand and the pump would sieze. Let it sit for about 15 minutes, and it would fire right up and go for another hour or so. On the highway I wouldn't be able to get over 55-60mph as the fuel pump couldn't keep up with the demands of how much fuel the engine needed. Check out the fuel pump, and possibly alternator.

I agree with the fuel pump, had similar problem with my grand wagoneer, turned out to be the fuel pump. :o

if it is the fuel pump, here are the part numbers and prices. if it is stock.

6470310 305g(l69) $44.05
6470422 305h(lg4) $34.48

just bored at work... hope that may help you a little. :D

I feel your pain brother, this is quite possibly the longest 12 hours I've ever worked. Very slow today, but a great time to catch up on here...hehe

Ha! you got that right. they keep buggin me a damn used s10. they want to know how much something cost, and when i tell them they dont want it b/c it is too much! and they keep coming back and doing it again. is it 6 yet??

well after 2 hours running around town to get a temp. sending unit. that ended up being my problem.put the new one oneand runns great.

Wow that's different :o A temp sending unit causing all that heartache!
Glad you got it fixed and shared the problem.

How did you get onto the problem being the temp sending unit, if I may ask?
Dan

i noticed the temp. gauge wasnt working . only showing about 130 degrees on the gauge.drove around a while this morning ended up having same problem but not as severe. so i will be replacing the carb. after taking the carb apart found screws broke and it was bent. so thats causing it to leak.i know ill be replacing almost everything since the truckk seat so long while the previuos owner let it set so long. just hoping that was the fix so i could drive it.

Ahh haa :| as the wheels turn, sorta like a soap opera eh.

ok ive replaced the fuel pump put a different carb on and had the altenator checked still has real bad hesitation and tries to die around 35 or 45 anyone have a suggestion

vacuum leak? look at ALL the hoses and lines. also if you put a different carb on, check the float level? maybe, hard to guess....

Do you have a EGR valve? If you do , disconnect it & drive it. If it doesn't hesitate, replace the EGR. What kind of carb are you running? Jon.

i put another rochester quadra jet on it.

If you have an oxygen sensor, try replacing that.

i already replaced the oxygen sensor and i tried disconnecting the egr valve still no luck. so far this is all i have done new plugs,wire ,rotor button ,cap, oxygen sensor,temperature sensor,carb.

ok im starting on replacing the timing chain today anyone have a suggestion on this project

I didn't read if you had a cat still on the car. Any chance it is plugged. Cars do not run very well when they cann't breathe.

yes it has a cat but i was told to let it warm up if it starts glowining it is bad. still getting plenty of exhuast out that back fumes are really strong though. drove it yesterday and now i cant get over 5mph.got it kicked out of gear enough let it roll down the drive way and could hear the chain loud . while the engine was uff

You should not hear the timing chain when the engine is off. If you hear anything when the engine is off, the car is rolling, and the transmission is out of gear, you have problems somewhere else.

Charles

ok i pulled the timing chain tonight. well when i pulled the damper off i couldnt keep top center lined up.is there an easy way to check tdc? the chain was almoost able to be taken off without removing the gear. it was stretched bad enough and the plastic coating on the gear was almost completely gone.next questions is. i got a steel gear instead of aluminum withe the plastic coat. is there a difference good or bad either way?bye the way thanks for the help to you guys through this project

The all metal timing gears are what you want. The nylon coated gears are notorious for cracking and sending chunks into the oil pan. Glad you got it figured out.

Charles

ok i got the timing chain problem fixed.still having pretty much the same problem as before.but now im getting a real strong sulfur smell from the exhuastanyone know what my problem might be now before i go to the last resort of dynomite?

The sulfer you smell is normal from a high mileage cat. converter.

Charles

ok i pulle d the cat. off and its empty pulled the hat valve its wide open (stuck) i have a sulpher smell still can get over 25 mph anyone else thinking ecm?
