I had the same problem in my 1995, i took it to the dealer and they fixed it. I think it was a very simple fix, but it was many years ago.
Sounds like a broken clutch spring.
The Subaru Impreza does not have a fuel pump inertia switch. If you are having fuel issues it could be the fuel pump relay or fuel pump.
A noisy fuel pump in a 1995 Subaru Impreza could be a sign of oncoming failure. Check the pump for the source of the noise, and it is probably a good idea to replace it.
typically $250 - $300. just paid $260 to do my '02 impreza RS.
it could be one of the sensors crank shaft or cam shaft
Generally speaking, a rebuilt transmission for a 1997 Subaru Impreza will cost between $2,000 and $5,000. It could be more or less, it depends on the parts put in and the worker labor charges.
A few things occure to me. Something's wrong with your clutch's hydraulic system. Out/low on fluid and needs to be bled. Possible bad slave cylinder or clutch master cylinder. Possible it just needs to be adjusted but most hydraulic clutches don't adjust so you'll have to check that out. Your clutch has gone out and needs to be replacesd.
It could be caused by a bad modulater, plug screen or it needs a overhaul
Yes, along with dozens of other things.
If its the engine knockins their is no connection just a quicondense. If the knocking is in the rear could be a cracked rotor or something.
I got one for $35 from a Subaru graveyard, but I've been quoted for up to $200. Napa was the only car parts place that even had a way to get it, and they're the ones who told me it would be $200. Try the Subaru dealer first, or try to find a used Subaru in a junkyard that you could get it from.
It depends on what is wrong with it, a minor problem could run as little as 100 dollars while a transmission replacement will run a good 2500-3000 dollars.
