Need some help
Ok well here is the story bought the car not running blah blah blah, got the car running good so I started fixing/modding the car. After this winter(RB exhaust,emissions removal,Tid,Wastegate porting, Walbro) the car is acting funny.
It was starting just fine, I fixed the few small leaks I had and decided to go for a drive. I went around the block four or five times, then as I pulled into my driveway the car died. I pulled the plugs and they were black( I figured that It was just because the car had been idleing for 30min before I took it out.)
So I went and bought new plugs and was going to adjust the timing thinking it was just running rich due to bad timing. Well now the car wont start, it keeps flooding, but just the top plugs are getting wet.
I checked all my connections and everything I had off, but nothing has worked, and Im out of ideas. You guys got any?
*edit* I also put on new wires and re stabbed the cas

Hmm I guess I dont know If I did anything with it, I blocked off the acv, split air pipe and took off the air pump.
I guess dirty injectors are very likely but why are one the trailing plugs getting wet? and why did this just happen all of a sudden?

do a search for unflooding procedures (pulling plugs blowing out gas).... but don't inject atf or any crap like that in your plug holes. if you have to do that you don't have good compression in the first place and it will mess up your cats.
when i had flooding problems i found that half the time the unflooding procedures i went through would not get it to start again. what did help was unflooding the engine thoroughly (being careful not to burn out my starter) and before i put the plugs back in i took a brass wire brush and scrubbed their tips with it and then heated up the end with a lighter or mini torch (not too much) to burn off all the residue that was fouling them. your other option is a brand new set of plugs... but ngks don't grow on trees where i'm from. you should get a timing light as well.
if the car isn't even trying to start i'd say it's ignition/plugs/flooding but i would double check all that crap you removed/modded too.

I already did all the unflooding, the plugs arent getting black just wet guess I should have said that. I put new plugs and wires on the car after my drive but it didnt help. I have a timing light but it's hard to set the timing when the car wont start, thats why I restabbed the cas

Make sure you still have the vacuum line to the FPR. If it is removed, the car will run super rich.
I see that you have installed a Walbro pump. Check your fuel pressure, because odds are it is quite high. The stock FPR can't bypass that much fuel, and thus the pressure rises.
Your plugs are black likely because of the extended idling and the fact that you are super rich.
If the car is seriously flooded you will need to introduce oil into the chambers to build compression again.
In a rare case, a fuel injector can get stuck open. You can test this by removing the upper intake, jumping the yellow test connector at the passenger shock tower, and turning the key to "IGN". A stuck injector will be firehosing fuel into the engine. Though I doubt that this is your problem.

it should go into the intake manifold somewhere.....prefereably the ones that are closest to the TB.....hmm....mines been running pig rich too...maybe i should look into aftermarket fpr

I would suggest just trying to unflood it really well and maybe cleaning your injectors.

Well the FPR is good, but I did notice that my Air Supply Valve was unplugged. Since the car has no P/S I dont think it's gonna help any, but I plugged it in anyways

Well I just got back in from trying to start the car here is what is strange. Only the top plugs get wet, the leading plugs look perfect like they are straight out of the box. I know when the car used to flood all 4 plugs were wet. Could this be a fuel problem?
*edit* the trailing coils ARE firing

i don't have a housing around to look at, but i think that they may be dry because those plugs are less exposed to the combustion chamber. i would pull the plugs, ground them on the chassis or something, and turn it over and make sure they are firing. then you know it isn't a spark problem and you can focus on the fuel, compression and timing.

Well it's been a few days, it's really hot out, been out on the lake.
I just went out and tried what ted suggested, still no luck. So here is the score, has compression, spark, and fuel just wont start. Im lost, and I would really like to drive this car before I die.

Ok got the car running again, I threw the timing light on it and the leading is dead on, T1 is firing randomly and T2 is firing the same time as leading!?! The resistance on the trailing coils are in spec and so is the CAS. Ideas?
