kinda long, but need help on why no start!!
 
ok...installed my turbo last week. setup is as follows:
d16y7-obd2
dsm 450 w/ resistor box and safc
td04 off '02 wrx
ran the car tuesday open downpipe and it started right up on the first try. i pulled plug wires and cranked a few times to get gas to injectors, oil and coolant to turbo prior to first try. car idled like normal, but ran rich since i had settings on safc at:
-38 decending to -35 up through upper rev range.
had my car towed to the muffler shop to get the downpipe made since i boiled my clutch fluid (turbine exit right at clutch bleeder screw) and didn't want to keep killing it and i needed to bleed the system to get clutch to work properly anyway. car cranked up just fine to get it on flatbed and getting it off into a parking spot. the muffler shop had car for 3 days and i had him drain the gas tank too since i had a full tank of crappy 87 octane in it still.
when he was done i put a gallon of 93 in tank and car cranked right up, but then stalled since clutch hadn't been bled yet. then car would not restart and i ended up flooding it.
i've pulled and replaced my plugs and it still won't start.
things i've checked:
i'm getting fuel because i can smell it in the cylinders and on plugs when i pull them
i'm getting spark-checked power at distributor and pulled plug and attached it to wire while my wife cranked it and sparking
i checked resistor box resistance and it's ok
all vacuum lines are connected
wtf!!! why can't i get the damn thing started? it sat for over an hour waiting for the tow truck to tow it back to my house and another hour while i went and got new plugs. i pulled the plugs before getting new ones and they were definately real rich looking and hoped that the cylinders would dry.
somebody help me before i set this damn thing on fire!!!

damn dude. try this: if u said u flooded the engine take out all ur spark plugs and crank it so all the fule evapartes. or let it sit so the gas evoparates. then screw the plugs back in make sure they are dry. take off the airfilter of ur turbo so as much air goes in, and try to crank it without pressing the gas. if that doesnt work, check ur distributer if it has constant spark, cuz i had the same problem on an altima sometimes it would give spark and sometimes it didnt. also see if ur timing is rite. I dont know if this will help u any but thats what i would do. i hope it helps. good luck.

someone said i probably washed the cylinders since i flooded and have no compression now and to pour a little oil down the plug holes to regain compression. sounds like it may work. i'll let it dry out overnight without the plugs and see if it'll work tomorrow.

do you think i should change my oil since it may have gas in it?

i'm also going to reset my safc to 45% low throttle with correction of -42 and 46% high throttle with correction of -38. this will yield the equivalent of 260cc on low throttle driving and 280cc on high throttle driving. does this sound right to anyone? i figure i will be in vacuum on low throttle and boost on high throttle. this is why i'm thinking of these settings.

if i'm not mistaken the stock honda fuel maps go rich at 50% throttle.

alrite if u have no compression it probably is the timing. do u by any chance know the people who work at tthe muffler shop? they might of played around with ur engine(revving it and ----) and the timing belt couldve skipped and couldve probably bent ur intake valves. have u done a compression check or are u asuming? If there is absolutly no compression , zero it probably is the timing(bent valves). if there is little compression pour like an ounce of motor oil in the cylinder and check it again. if the compression raises by 5-10 psi it might be ur rings. i highly doubt it tho.iam just giving ideas u can try them or dont. good luck either way

Something similiar happened to me before too. I drove and hour to go see me girl and it rode fine. Then when I tried to start the car the next day it wouldn't start! Turns out that the O2 wires had melted together and were grounding each other out. You could check the O2 and wires to make sure they werent fused together. Sounds like the exact same symptoms I had (car cranks, smell gas). So check those wires!!

Don't put too much oil into the cylinders, but it can help. Find someone with a leakdown tester to see how much air the cylinders hold and if they leak out, where from? that should let you know what's up there. Also- get some $0.99 plugs so they aren't expensive to f-up for tuning. tighten the gap about .005 or so because if you cylinders are really full of gas, it might be harder for the plug to fire when it's actually in. Also, just because the wire has spark, the plug doesn't always. Good luck.
