Default Turbo prob! help

Ok, the turbo is on, oil pan and block tapped in to, air/fuel and boost guage wired up, vortech FMU set up. The car cranks but DOES NOT START. Before hand we disconnected all the plug wires off the distributor, cranked the motor for approximately 10 seconds, we did this 4-5 times to prime the turbo with oil. Then we connected the wires back up to the distributor and cranked. The motor cranked but didnt start. We could smell gas, so we figured I was flooded big time. This morning we tried again and again till now, and still cranks but does not start. At first we thought the firing order on the distributor was wrong so we rewired. Nothing. Now we have it back to normal I belive. However, before I even installed the turbo I moved the distributor back towards the fire wall a little, so the bolts holdng the distributor in were about in the middle of the hole. After the install, while cranking we tried moving the distributor little by little both ways to find where it could work, some times it felt like it was gonna start but didnt, even in the position it was before I messed with it. Now I've disconected the FMU thinking it was faulty and duming too much gas, Im currently running on an after maret FPR set at around 40 PSI. After cranking the motor and pulling out one plug, it didnt seem to be wet with gas. But car still not starting. I can smell gas in the exhuast, also while cranking I can feel small back force from the combustion and it goes like this, bmm bmm, bmmmb, bmmm. Feels like wants to start but doesnt. We think its time related. Any ideas any one or advice, man I am stumped. HELP people.

No idea man, You messed with your timing? Id get a timing light and see where its at. Did u try hooking the stock fuel system back up? U can run the stock system no problem, just dont let it see boost. Honestly man, ditch the crappo boost reliant FMU and go wire youre greddy blue box up, its electronic so at least it lets the computer know its there.........im guessing the timing is messed up? Did u try pumping the gas pedal as you were trying to start it?

It would start even if the timing was as off as you could get it. It would just run like poo. My guess is you forgot to hook something back up. Maybe the plug to the dizzy? Have you actually pulled the fuel line to see if you have pressure? Just crack the bolt on the filter and see if fuel comes out. Have you checked to make sure you are getting spark? Ground a plug that is still connected and turn the starter over and see if you get an arc. Checked all of the fuses?

check the spark plugs and see if they are fouled..

also check for:

compression
spark
fuel

Before I say anything else, I am running the stock trim plugs right now. The NGK colder version wont be in till tomm.

I tried runningthe stock system, still wont start, same result. I tried pumping the gas, WOT, not touching the pedal, still doesnt start. If the timing is messed with on the distributor, Im guessing it will still run but not as good. In m case its not starting, I moved it from one side to the other.

It would start even if the timing was as off as you could get it. It would just run like poo. My guess is you forgot to hook something back up. Maybe the plug to the dizzy?

We hooked everything back up. On my aftermarket FPR we tried raising, lowering pressure, nothings working. And I do have pressure, when I crank the arrow fluctuates. I am getting spark. We grounded all four sparks and all had spark. We gaped them to about .041, roughly what honda reccomends. Also, half the time when we cranked for a while, or raised the fuel pressure, the plugs were wet. Other times we lowered fuel pressure, and the plugs were normal, but no start. I checked the fuses in the engine compartement, everything seems good. However, my friend tapped in to the parking light fueses in the car for the boost guage light, but nothing that would have to do with the starting.

It appears that we have spark, fuel, and we messed with timing. Few times the car was really close to starting, I mean on the brink but then slowed down. Far as compression goes I dont know. Is it possible that the exhaust fan on the turbo is too stiff for some reason, and isnt turning as well as it should be, and that inturn makes too much pressure for the combustion to turn? The fan can be turned with a finger, fairly easty to turn, but I dont know how easy they are supposed to be, it wont keep spinning if spun just once. ANY one else????? I am running out of options, and getting depressed here.[&o]

Im wondering, since the turbo is used, and maybe the exhaust fan is not free spinning as it should be, and creating too much back pressure for the comubstion to turn. I really dont know. I hope the kits not a dud.

What exactly is it doing when you crank it? Is it freely cranking or what?

is your motor cranking like it has a brand new battery or like its been in there for a year or two. try a new battery. sounds like you need all the cranking power you can get, also do a compression test on the motor

Its been about three days since the car ran. Then we disassembled. We tried cranking it at about 6:00 am yesterday, it didnt start. Thats after we primed oil. At first it was cranking freely. Then slowed down some. We put it on a good battery charger afterwards and it sound really good. Cranks like its gona start, but doesnt. I have an optima battery in the car right now, thats like a year old. It has plenty of juice. Sacicons thinks I either got the firing order possibly wrong, or the ecu. Im wondering if my coil can put out a spark strong enough. I've never done a compression test. How so you do it? And would that make a difference. Thanks for all the input guys.
