Samurai dead (HELP PLEASE!)

Ok everyone, i have a 1989 samurai with carb and all of california's fav polluition control gems on it!

Up until yesterday my samurai ran like a champ, started up easily!

Yesterday we tried to take the thing on a test drive, she started up with no prolbem, backed it off of a trailer and the thing stalled out. Weired seeing how ive had the thing idle on its own for 20 minutes or so without stalling.

Anyways, i thought there was a fuel delivery problem, pulled off the gas tank and the lines are fine there.
The fuel filter is brand new and looked fine with gas in it.
The steel lines are all new
The fuel pump works and shoots gas every revolution.
The line going from fuel pump to carb is clear

took the fitting that the fuel pump connects to out and the area was dirty, pic:


should that red thing be there?

Also: the car still runs if i pour gas right into the carb, so im thinking that rules out any timing issues..

Let me know zuk experts! i will take any pic that you need to think up some solutions!

If it does run while pouring gas down the carb it narrows your search. It does sound like a fuel issue. Does it idle now or nothing at all? Does it try to start? When you put gas down the carb will it fire up and run till that gas is gone?

Id say something is either bad at the pump or carb. Clogged jet perhaps. You said it was squirting fuel when the engine was turning over, but perhaps its not enough to fill the float bowl and keep it running?

If we pour gas down the carb it will run till that is gone.

When we crank it tries to start up, we are trying to get to the main jet but it is being a PITA.

WIll replace the fuel pump just incase and it looks like a simple job anyways.

re: bad gas

I was having some problems getting my LJ80 to run and it would start right up when I poured gas in the carb.

I put a bike gas tank on the roof of the LJ and hooked it to the carb fuel line and it started right up and rine fine. I knew then that there was a pump problem.

Turns out that the rubber fuel line in front and behind the fuel filter was rotten and there was no way for the fuel to get there.

Is your filter plugged? Is the gas good? Water in the tank?

new filter, newish gas, tank was drained and refilled (no water). Fuel pump DOES shoot fuel... buddy just cleaned carb, waiting for gaskets to come in for reassembly to finish trouble shooting.

there was an excessive amount of grime/dirt in the float bowl, shot some cleaner through the jets and removed built up kaka, hopefully the problem will be resolved,

I just rebuilt my carb from an '88. I had sank my truck in a 6' deep puddle and flooded the gas tank and a bunch of the bad things happened. Anyways, to drive it home I bypassed the fuel filter and as a result filled the carb with crap.

The whole process took about 3 hours and I had to buy a rebuild kit since the gaskets were broken during disassembly. I blasted the bowl with carb cleaner and removed lots of crap. Most of the crap was on the internal screen, behind the main fuel inlet port.

Go to www.suzukiinfo.com and get the FSM for the Samurai. There are 20 plus pages on the carb rebuild steps.

Thanks for the link on the carb rebuild... going through it right now (I am Simko's buddy doing all the fukn work)

The carb was dirty as hell, is it worth it to remove it completely off the intake to clean her right out? I only gained access to the bowl (way too many vacuum lines and other gadgets I didn't want to mess with) and removed a fair amount of junk in there.

I would say remove it, it's too much work to button it back up and have it do the same thing. I had a no idle condition on mine a few years back after letting it sit for 5 or 6 mos. I pulled the carb and tore it down enough to flush out all of the passages and re-assembled. It has run like a swiss watch ever since.
