akc Posted February 17, 2009 Share Posted February 17, 2009 He I am really having trouble with my 84 it has a weber carb but other then that is standard. what happened is I drove it the other day and it ran good but.. the hills were a real chore for it I actually had to downshift to first and usually I can make it up in 2 or 3rd. then I got there and turned it off when I went to restart it all it did was catch and run for about 30 seconds and then die. messed with the carb replaced the fuel filters replaced the fuel pump still will not stay started. I can not figure this out when we sprayed starter fluid in the carb it seemed to run better but... would still die. It was not getting enough gas (ie no pressure) with new pump it has more pressure but still will not run. sounds good for the 30 seconds it is running Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted February 17, 2009 Share Posted February 17, 2009 Welcome! ...the 30 seconds it is running Sounds to me Like an Stickin` Float... Maybe it is Drowning in Fuel, did you Smell Gasoline when it Happens? I Believe that your Weber Got Dirty, Dirt can Clog the internal Passages, so I Suggest you to Take it out and Clean it, then Carefully Check the Float Level. Good Luck!

akc Posted February 17, 2009 Author Share Posted February 17, 2009 No it does not smell like gas. We have pretty much cleaned the carb. we have been messing with it for two days now. will check the float levels again. it seems to have enough gas to start it but then it is like it does not get enough to keep it running?? I think?? even with you pumping the gas it just dies off. but then starts again fine. it restarts like it never even had a problem. Link to comment Share on other sites More sharing options...
ihscout54 Posted February 17, 2009 Share Posted February 17, 2009 After it dies pull the top of the carb off, and check to see if there is fuel in the bowl. I would also pull the idle jet (brass screws on the front and rear facing sides of the float bowl) and clean them out too. Especially the front one. They may appear to be a solid unit but they are 2 pieces. Separate them to clean it. Link to comment Share on other sites More sharing options...
Cougar Posted February 17, 2009 Share Posted February 17, 2009 Make sure the ignition is working when this happens. If the engine control doesn't see ignition pulses it will shut the fuel system down. Link to comment Share on other sites More sharing options...
akc Posted February 17, 2009 Author Share Posted February 17, 2009 I checked the float?? in the carb after we had pumped the gas it was mostly empty so we started going back. when you started the car the gas was good but then after it was running a few seconds it would stop. I am not sure what the problem was as we went and checked all the fuses after we did that it works fine so aparently one of the fuses was either loose or corroded or???? or we bumped something and it started working again who knows?

Loyale 2.7 Turbo Posted February 17, 2009 Share Posted February 17, 2009 Now, I Really Believe that This: ... If the engine control doesn't see ignition pulses it will shut the fuel system down. Could be the Right Answer. To Test that, I Suggest you a Simple idea: Remove the Wires from the Electric fuel Pump and Run a Direct Wires from the Battery to it, to keep it Pumping; Then Start your Subie... if the Engine Stays Runnin` without Stop, That`s the Problem and the Proper Solution could be Found easily. Good Luck! Link to comment Share on other sites More sharing options...
ivantruckman Posted February 17, 2009 Share Posted February 17, 2009 ive had the float valve stick on me . ie...the actual float drops but he pin sticks in its bore, a little 800 grit paper fixed the burr in the seat Link to comment Share on other sites More sharing options...
bheinen74 Posted February 17, 2009 Share Posted February 17, 2009 check that the fuel line near the pump/filter is not KINkED/collapsed on its self on a bend. . Link to comment Share on other sites More sharing options...
Gloyale Posted February 17, 2009 Share Posted February 17, 2009 Make sure the ignition is working when this happens. If the engine control doesn't see ignition pulses it will shut the fuel system down. If the car is running, Wouldn't the ignition be working? And that "rev sensor" which controls that function would operate immediatle. Not on a 30 second delay. car would not start at all. I believe you're float is either sticking or adjusted too low.

akc Posted February 19, 2009 Author Share Posted February 19, 2009 I do not think it was the float because when we pulled the gas lines to the carb. when you started it it sent out a gush of gas then nothing unless you really pumped on the gas then it would send a tiny steam. So it had to be some senor or something that was telling the pump to pump. as It was before the gas even entered the carb. there was no kinks in the line. Good news is what ever it was seems to be working if it happens again I may try testing the sensors or something like that that would tell the fuel pump to pump. I know the fuel pump works as we tested that. The mechanic friend that came over and help also mentioned that some of the fuses and fusable links had some corrosion so it very well could have been that. But at least with all the tinkering it is running better then it has in a long time and finally idols nice too.but I think we may have ajusted the carb to low now it takes longer to start I cannot believe the difference though it was really having trouble making hills and now it flys up them I might actually get a speeding ticket now. before I was lucky if I made it up a hill on the hwy doing 45 now I do not even have to downshift most of the time wow. it may have been several things dealing with the fuel system. Just curious what kind of MPG does your Subarus get? Link to comment Share on other sites More sharing options...
