I recently bought a 96 legacy sedan with a 2.2L auto. when I bought it, cylinder 4 was cracked. so I got a used short block and pieced a new motor together a few weeks ago. upon installation I replaced plugs, wires, fuel filter, p.c.v, timing belt etc. it ran great till last Friday. I went out to go to work and it wouldn't start. I pulled the hose off the fuel filter to make sure it was getting fuel, and nothing. so I put a new fuel pump in it, still nothing. after playing around under the dash trying to locate the fuel pump relay, it started. the old relay was so hot that it almost burned my hand. so I put a new relay in and it ran great again. today I pulled into the gas station for a second (didn't get fuel) came back out and wouldn't start. finally got it to fire and was running rough. so I hooked my computer to it and found cylinder 1 and 2 are misfiring. if I attempted to give it gas, it would only make it worse and then die again. now I cant even get it to start. any ideas? maybe something small that I am missing here but any help would be appreciated.
