OK, I am clearly paying for my $200 Craigslist car with sweat equity... and possibly parts.

So, 1978 Volvo, B21F, K-Jet FI. Car ran but not well, tried to adjust timing (was at 0 degrees vice 12.5), ended up breaking the distributor, and I just replaced it yesterday with a known good one from Dave AKA Volvo from heck.

Now, car will start, but only if floored. It will not go above 800 rpms for anything, and really wants to die if you take your foot off the gas. Absolutely gutless also, even floored will not move the car. I added about 5 gallons of gas yesterday, seemed to make it run a tad smoother.

I jumped the left side of fuse 4 and 6, and heard the relay hum, and clicking from the main fuel pump, but it did not appear to be buzzing and pumping.

Previous owner supposedly replaced both fuel pumps and the filter (they do look new and there's evidence the in-tank one was done as well). Filter weeps just a tad on the inlet side. They also screwed up installing the timing belt, so it sat for a few months at minimum before I bought it.

So, is this a case where the pump crapped out, or could the filter be clogged? I may replace the filter anyway, need to stop the leak and its only $25. $100 plus fuel pump has me pausing though.
