fuel problem

this is really starting to bug me.

My sled appears that its not getting fuel to the engine.
so first off, how do you test fuel pressure? I have a feeling its the fuel pump. its a 19 year old sled (1990 indy 500), and it sat for 3 years before I got it (2 years ago) so I think there could be a bunch of crap in the pump...

If i blow into the tank, I can see fuel go through the filter, but when I pull on it, it doesn't draw any fuel.

I also think the engine would profit from a re-build, except that snow's here and I'm not gonna do that now.

I talked to a guy, (one of those guys who knows something about everything, but usually just enough to be dangerous)
and he said that it could be a crack where ever the pipe comes off the engine for back pressure to the pump. but I'm really hoping its not that.

what brought all this to a head is that I ran the sled out of gas tonight in the field, down the road 1/8 a mile, and now it won't start. but I'm pretty sure its flooded (kind of an oxymoron, being that it was out of gas lol)

There is a pulse line coming from the engine that can crack, but is easy to replace. First, disconnect that pulse line from the engine and have someone pull the engine over while you have your finger a little away from the end and feel if theres any pressure coming out of it. If there is, check the fuel pump next. Connect everything back up and then take the line off by the filter and feel if theres any pulling presure there. If not, then you have a bad fuel pump. If i sound confusing just tell me i could make a vid maybe for you.

There is also a gas line that goes into the gas tank and if you dont have atleast half a tank, it wont suck any fuel. Take a flashlight and look to the front of the gas tank(toward engine) and see if it fell off. This is a common problem with sleds, ive had it happen numerous times to diff. sleds of mine and friends! Hope this helps!

ok i'll have to look at that tomorrow after i get it out of the field... that'll be interesting...
I have some fuel line of the right size here, so maybe while I'm ripping that all apart I'll replace all the fuel lines too finaly

Nope standard wedge chassis never came with parking brakes as i know of. Ive never seen one with a parking brake. They do make parking brakes on other sleds but not these ones. Yea i kinda wish they had one.

ok so today, I took the belt off, hooked it up behind my neighbors truck and pulled it up onto the road, and into his farm yard. now i have to figure out why its not running. seeing as i ran it out of gas, I wonder if the carbs were empty, and so wondering if when we started pulling on it yesterday, if then it flooded. i'm gonna go down to the gas station and get enough gas to at least have a half tank. when I pull, I can't see it sucking gas, but the filter is staying full, and its clean, so unless theres a blockage between the filter and the engine, I'm also gonna pull the plugs and see how they look, if there wet or fouled, yesterday it was getting dark and we didn't have a wrench, so we unhooked one of the wires, and put a spare plug in it, and it was sparking so I know its not electronics.

I always wonder why my sled only has problems after snow flys... when i get it out fun the fogging oil and stuff out of it it never has any problems lol...

MWUAHAHAHA!!! I HAVE FIXED IT! lol
well. almost.
It was a spark plug problem.
I pulled the spark plugs, then pulled the drain plugs, maybe a 2 teaspoons (yeah i know... kitchen utensils lol) of gas or some other liquid, I didn't bother to sniff it and see, came out.
so then put the back up on a stand, and pulled it over a bunch of times (why cant it be that easy to pull over when the plugs are in...) and some more junk came out. then I put the drain plugs in, went and got new plugs, which are the wrong kind (NGK BR8ES, instead of NGK BR9ES) and put those in. then I filled the gas tank, and pulled twice and it started right up. so I let it warm up, and ran it home. I then had to do some stuff at home, and when i went to go around the feild a few times, it wouldn't start, and I ended up pulling the plugs about 5 more times and drying them off, and finaly it started. The plugs are getting wet and fouling after 2 or 3 pulls (leads me to beleive the mixture is off...)
My dad says its probably becuase the plugs are 8's instead of 9's, and thus not hot enough... so I'm gonna go hunt around town on Monday and see If I can find some 9's and see if that fixes it.

8's run hotter than 9's... it sounds like your carbs need a good cleaning as your needle is not seating and is flooding the engine as it sits there.

well carb cleaning is probably what is then... its a 19 year old sled, excellent condition, and I'm the fourth owner (that I know of.), and I know the guy i got it from did very little engine work except fogging it in the spring, and running stabil in the fuel before storing it for the summer. and it sounds like the guy before him did practicaly nothing to it... another project for summer. unless this junk continues... then it will be a project for christmas break.

I know, I've had the carbs off an Indy 340 or 400 before... can't remember which... unfortunately my life knows not any time to waste... except today when i could work on the sled for about 3 hours which was nice... so it looks like its gonna be Christmas Break...
