truck will run initially; then motor will hardly run. i took off rubber run before intake and put my finger on vaccum pipe and theres suction so the vaccum is working. my diesel is down so i need the gasser to work. the motor is not running hot. it sounds ok just when its warmed up, its like its starving for gas or not burning it. i smell no excess of fuel. anybody have this this problem and have any ideas of what to check? thanks
Check the fuel pressure, and quantity... There is a WUR (Warm Up Regulator) that can work when hot...(which it isn't supposed to do).
I defer to the more knowledgeable CIS folks.

thanks briano. i noticed tnat there is a rusted out pipe that is plugged on top on the left side of exhaut manifold and a fitting on yhe right side of the exhaust manifold. theres a white plastic part with a long section of hard plastic hose that goes to nowhere.i looked at the fuse pael and it was dangling. the gas gauge does not work. i looked at the wiring by the fuel pump. the check valve is hanging loose but looks alright. the ground wire on the tank isnt connected to the frame. runs good when its sitting. i take it down the road and it starts midding. could the coil be overheating and causing the miss? just asking questions. nakona1
Coils do go bad, but the Electrical is more iffy. New Grounds to the frame and battery as well as the power cables goes a long way to making them more better. The fuel gauge could be a bad wire, or the gauge, and I usually connect a battery 9v to the sender wires to see if it will deflect the gauge. If your Temp gauge isn't working then that is the 10v stabilizer...

itsa little disapointing that i have the most responses to this thread. i took off air cleaner assembly. underneath the old filter was a mouse nest. i replaced air cleaner and removed the mouse nest and have ordered both bentleys i need to get both the diesel and the gasser running. the gasser should be the least expensive to get running if i can narrow it down. i looked at the cis info in a newer member who was getting alot of help for his wolfsburg and i obviously need to invest in testing tools and other tools. my dilema is i can get a free garage and i have no vehicle to take it down. i have until aug. 1st to remove it. i have nowhere to store or work on anything.
i replaced the fabric connectors with new rubber on all the vaccuum lines. no help. one part has no hose on it. its on passenger side of intake. it does not look like its on the vaccuum scematic yet it has yellow paint on it. the yellow line is hooked up to the back of another part in the babk of the intake. i would like to rep[lace some of the fuel lines that have bandjo fittings as they look pretty ratty, but i dont have the tool to do this. when it start this thing up, its sounds fine,; when i put a load on it and she loses fuel/air or pressure. stuck in n. wi. nakona
Do yourself a quick favor..... Disconnect the exhaust manifold from the down pipe. (you should have 2 "c" clips) You can wing them off with a Philips screw driver.
If your exhaust system is collapsed (Mufflers rot internally) that can restrict the air flow. I have had a old Toyota that would idle fine, but give it gas and it would choke sputter and die.... The Muffler collapsed internally, and didn't look to be bad. Think of the old potato in the exhaust....
To replace the clips use a muffler clamp backwards.
We all have been where you are....

the exhaust is not good and needs replacing. i will look into droping the down pipi. there is little coming out of the muffler. briano, i will upgate. thanks nakona1
briano, i looked at the back of exhaust manifold and it has6 studs on the down pipe and a three bolt flange before the spring/cat on both sides. i will order new exhaust pipe and muffler, everything after the cat from parts/geek. the price is pretty reasonable. i will let you know if this does the trick. i hope it works. nakona1
briano, i dropped the exhaust. the ears were rotted out on the end of the spring/cat combo so i will have to replace from the end of down pipe on. i tried to get the gasser to run and now she wont idle. if i can get someone to crank it over and i will see if i can get to run. the bentleys came today from partsgeek- hardbound and reasonable, so i will read up. i noticed when i took the rubberboot on the fuel distributor. that stainless top with a flat cover was dirty on the top and when i pressed down on that flat it wouldnt go down evenly, like its hanging up on one side. is this normal? i wanted to take the bolt out to take a peek but was afraid to screw it up. i will see if there is a blowup in the bentley. will keep you informed. nakona1
I know about that fuel dist system but don't dink with it too much you have to use a magnet. It shoudl move up and down. Others that are more CIS oriented will assist you shortly.

i looked in the bentley and it isnt real clear if i take the plate off to inspect or clean lever to see if its working. i know i need to to jumper wiyh the ignition off the fuel pump to do the magnet test. i looked at the fuse panel in yhe electrical section ans it shows 81 or later and where to jumper it. i will try to cowboy it out. the bentley is not always clear on where to break down something to inspect/clean/lubricate. i wsh the cis cavalry would respond. nakona1
i am work ing on grounds and the exhaust. i took the negative cable to napa and a couple other auto parts stores and the cables do not have the the heavy ground that the oem cable has. do i get a proper length cable and make a heavy enough wire to go to the body mount and mount that to the battery terminal bolt?
next i removed the exhaust all the way from the down pipe. both the end of the flex pipe and the end of the cat are rotted out. Question #1 is when i looked through the cat and the flex pipe i saw a circluler donut like thing n the cat. i can see right through so is the cat bad and does this affect my fuel delivery problem? should i spend my limited money on the cat and o2 senser? there are other mounts on the exhaust that the parts are rotted or gone. the question of the new cat will affect whether i take one of the old pepes, cut off the end and weld it on either the old cat or the flex pipe. i can order a triangular plate that should work to weld on the other end.
i will kep you men and women posted on further trials with the gasser.
i went a couple hours away and took down a 2 1/2 car garage that i am using my government money next month to move it. its coming from cloqet mn to my place in park falls wi. if i could buy a good used flex and cat from one of you that would be cool. i also need a new replacement fuel tank for my 1.6 diesel caddy. thanks for reading this; your help is always welcome.
it is a 81, take the cat and remove it to a shelf, ya don't need it.
The grounds are easy, take your cable and go to a autoparts store and buy 2 cables to replace the 1.
One from the battery to the frame ground, and a Jumper from the frame ground to the engine/tranny.
The 02 sensor can be bad, but get the generic one that is 1/3 the cost and splice the wires to your connector.
Remove the Cat, Weld a Straight pipe in it's place. The circular thing could be cat gut, or the gasket from the manifold /flange connection.
If you have to have a cat, then gut it out and use it as a straight pipe.

briano, the origional negative cable had 2 wires; the main going from post to engine , the smaller to the unibody. so theres an asvantage to go from post to unibody, then engine/ trans? thanks how hot is it in ga? it was close to 100 today!
It twere but about 90 or so.. I don't really know as I sleep most days... So when I get up it is usually a tad cooler.
Yes you can use 2 separate wires to ground the engine and battery to the frame at the frame horn mount, I have used 2 cables on all my cars usually.
Getting the wires at the "Auto Jobber" of your choice is a good thing. I just have a good Discount at a couple of local to me stores.

briano: im lookin at the bertly, and i noticed an expansion tank and a charcoal filter and i dont have either on the gasser. theres no o2 senser on the cat, just a radiator clamp over the hole. whats neccessary to get my gasser goin? thanks, nakona1
The 81's probably didn't have those, but I can't swear to it as in late 80 I was driving a 81 Rabbit Diesel off the showroom floor. I would look at www.cabby-info.com the DIY or troubleshooting sections, as it could be off on the timing, duty cycle, or a bad WUR.
