Does anyone have any insight here.
86 1.3
Took it out our hunt camp this weekend just to play. It ran great for about 45 minutes then as driving along it would just die. It 's like the fuel just shuts down.
I changed the fuel filter and the check valve, That wasn't the problem. I then went into town and bought a new fuel pump, That wasn't the problem.
It seems like it runs fine until it gets to normal running temp then it will go for a couple hundred yds and die, You have to wait 5 minutes or so and it will fire up for another couple hundred yards.
I then drained all the fuel (full freaking tank) and it ran great for close to an hr so I figured it was bad gas. Well low and behold the thing died again.
What the hell is going on with this thing? Any ideas?
-
that was happening to a friend and we found it was a bad ECM
if you someone with a sammi swap out the ECM and see if that helps
-
Also, check your ground connections! Especially the one to the distributor. Look for black ground wires attached to grounding points on the body. These things can cause intermittent loss of spark although I have to agree with the flaky ECM diagnosis, too.
-
I had the same problem in my SJ-410, ends up the carb was plugged up. New carb, problem solved.
-
I'm hoping that I don't have to spend a bunch of money on the carb but if I have to then I have to I guess. I'll check the ground wires and the ECM first and see what happens there. Thanks a bunch guys.
-
Can someone tell me if this will fit my 86 1.3?

Check your choke first, and then make sure your down pipe has not collapsed if stock. (my 88 was it has an inner walled pipe)

What about the redneck carb clean. Maybe something is floating around and blocking up a passage. ??? ??? I would try that since it can't harm anything. ;)

I did that last week and am thinking maybe something broke loose. I am ging to try it again and see if I can't flush something out.

Euh...what is that??
-
i'm not sure what a redneck carb clean is but i experienced a similar problem (ford truck) and it drove me nuts until i found the little rock in a fuel hose near the tank.
i think that little rock would roll up to a metal fuel line and plug, roll back when fuel not being drawn (like after it died), but after a while i could start, be good for a couple miles, then wait awhile again.
i found the rock when i was working all the way back to the tank trying to find the problem.
just a memory of long ago.....you reminded me.
-
Ok, I haven't had time to mess with the sammy until today. I took it to the field down the street. I am still thinking fuel instead of coil, ecm, distributor and so forth. I rerouted the fuel line thinking vapor lock, That wasn't it. I started talking to a guy down there that is a mechanic and he listened to it start but then bog out. He said drop the tank, There may be an inside sock (filter) thats collapsing due to crap collecting on it. So, before I drop the tank I wanted to ask. Does anyone know if there is a sock type filter insode the tank?
-
Yes there should be a sock type filter at the end inside the tank. I find it highly unlikely that it is collapsed, or even plugged up for that matter. Unless you have been dumping crappy fuel in your tank.
-
My boys just bought it from a buddy that didn't have it for long and ran into harrd times. It seeems like a fuel issue. I pulled the fuel line while turning it over and barely fuel at all is coming out. The lines don't look kinked and I've already replace the filter,pump and check valve.Aafter doing all of that I drained the fuel and dumped 5 freah gallons in. It ran for close to an hr. and then died again. It could be the coil but It's getting spark. It just seems like it's starving for fuel when it dies out.
-
Try running it with the gas cap off, if it still does it you might have to drop the tank it's no big deal and there is no sock that I know of in a sammie tank(with carb) but does not mean that there is not something floating around in there, also use a fram fuel filter instead of say a napa gold there is alot more paper in them, the only thing I did to mine when putting the tank back up was to add a foot or so more fuel line to the top of the tank to make it easyer to put back up there by myself and have spare line if I ever need it.
-
Already tried it with the gas cap off and that wasn't it. I'm gonna drop the tank next and if that doesn't do it then I'm probably gonna drop the money on a weber. I'll add the line as well, Thanks for the tip. Any other suggestions out there?
-
just check the general condition of the lines. If a line or hose is cracked or has a pin hole could be sucking air and causing the problem.
-
I had a crack in the top of the fuel line coming out of the gas tank, didn't notice it until I dropped the tank.
Final issue ended being A) The cracked fuel line, B) Bad Fuel Pump, and C) Plugged Carb. Now that all three are replaced, it seems to run fine. :P
-
I found a carb that I'm thinking of getting 32/36 Model DGAV-33B1. The carb does not come with an adapter plate so is that something that I would have to pick up as well? If so, how much we talking?
-
Ok, I dropped the tank and there was no sock filter in there, I cleaned it out as good as I could and it didn't look to bad in there. I replaced the 3 smal rubber hoses coming from the fuel lines and the 2 hoses from the fuel pump down to the fuel lines. I put it back together and it seems to be running great however, I can't get anything up above the gas tank to get that freakin hose clamp on the big hose going into the top of the tank. Any suggestions. By the way, It's leaking gas because of it.
-
I had to put that one on while the tank was dropped. The easiest way is to put a jack under the tank and drop it until you can get access.
-
Any possibility of doing the old cut-an-access-hole-in-the-floor-above-it trick?

Tried that, There is litteraly no play at all in that hose and no room to get a hand in between there.

I like your thinking. I am going to look into that when I get home. Thanks for the thinking outside of the box.

I disconnected the hoses at the other end. But I have an SJ-410 so the plumbing might have been a bit different. Beercheck's idea sounds good though. Just make sure you have some metal to cover the hole back up with. :)

update:
I removed the back passenger tire and got a long pair of needle nose pliers along with a long screwdriver. I was able to get to the clamp and get it back on. I also found a small leak and was able to replace a hose clamp and tighten it down. I do have one more hose clamp that I need a little longer screwdriver to be able to tighten but the most important thing is that i have fixed the problem with it starving for gas.
