I just picked up a 91 civic dx 4dr with a dohc zc swap. First, some back ground: Day i picked it up I noticed a slight hestitation at low rpm full throttle, thought tps might be out of adjustment(haven't looked into this). 2 days after I bought it the transmission blew up (broken shift fork) .. so I swapped in another trans. drove it around and it was running/driving good all day other than the occasional hesitation if I got on it too fast. I got home from work and it wouldn't start 2 hours later. It acted like it wanted to start, and started a couple times but died either a few seconds later or as soon as I touched the gas pedal, then eventually it was just turning over not wanting to start at all. I was close to E so I thought I might be low on gas. So I put some gas in it from the lawn mower can (not sure how old this gas is). Well it still wouldn't start. I pulled off the distributor and found it was seized up, wouldn't spin freely.. so I replaced the distributor.. and now its back to sputtering for a couple seconds and dying. I'm getting spark, fuel, I checked grounds, main relay is good, replaced fuel filter, plugs/wires are good, firing order is correct. No CELs. Hopefully someone can point me in the right direction?

well it only started a hand ful of times but when it did start it was either idling super low (under 500 rpm) or it would idle at like 1200 for a second then slowly die off in another 2 seconds or so. I will check the timing but I don't think that would be it... It was running great, I shut it off, then it wouldn't start again... but I guess it could have jumped a tooth or something. Could it be fuel pressure related? I've only put $25 in this tank of gas but I don't think i'm getting very good gas milage (maybe 16 or 17 mpg). -Edit- Forgot to mention, I'm using a pg7 ecu.
