New Engine! Wont start! Need Help!!!
hey guys im having a lot of fun trouble shooting here. i'll brief you on what i have done so far as trouble shooting. i have a new 3mm steetported motor, r85 single turbo, brand new engine harness, alternator harness, 1600cc secondaries, 850cc primaries (kg ultimate fuel system) also im running resistors for the 850's so thats not the problem.
i have checked both crank sensors they are both within resistance spec and are not hooked up backwards. i have jump wired the fuel pump 43lbs and holding. confirmed spark (lots of it with msd box and nology wires). have compression on both rotars. running two battery's in series outside of the car so theres enough cranking power. have verified that the map is set for 1600's and 850's.
car cranks and does not show sign of combustion. i will be going down right now to test the last thing which is taking off the upper intake mani and connecting 12v to the primary injectors to make sure they are working.
any other things to check over? should i try cranking on the stocker (if possible)? i've searched the 3rd gen specific and single turbo section with out reading anything that i have not already covered. please lend any advice or knowledge here im open to anything! thank you very much for reading.

if you are getting gas, air and spark... are you premixing, or omp?? Idk much about new rebuilt engines, but on a older engine of similar situation, you may be er, flooded, or no/not enough oil to seal?

also forgot to update that i tore off the uim and checked the primaries and yes the do work.
rich would you like to look over the map to see if possibly its spitting a little too much fuel in? if yes pm me your email.
any other responses would be greatly appreciated!

your talking the cranking (ms) on page two right! i was just thinking of that 5 mins ago. what percentages was he working with? do you think you could get those 6 plots for me?
i really dont think i have a setup problem or have anything incorrectly hooked up. i think im just running pig rich here. so the map looked fine to you...?

based on what he told me, you may be running lean actually. He told me he had to add a lot of fuel to get the car to start with the top feed 850s. I hope to get to the bottom of this problem on my car, at this point I'm just speculating. I'll be troubleshooting it tomorrow with Ihor, but we have to pull another guy's engine for him as well. It's going to be a late night, lol.

Hey Lance, I haven't been able to look at your map yet, sorry about that.
Good news though, we were able to get my car running with the new map, she fired right up. With the 4 inch straight through exhaust, she gives out a LOUD low deep rumble .
Are you sure your motor is flooded? plugs wet? a couple of capfuls worth of ATF in each spark plug hole should be enough, but when in doubt just toss more in. It'll all burn off

haha... rich you sob! must be nice to hear exhaust notes. im getting soooooo much vasoline build-up on the plugs with a nice glaze of fuel. it sucks cause i thought i got all of the lube out of the motor prior to bolting the longblock up. i guess tomorrow i'll put some atf in and cycle that beotch over! thanks for the concern and motivation with beating me to it

What resistors are you running? I assume by 850cc you mean 83lb injectors =870cc. I initially used 10ohm 10 watt resistors and couldn't get my car to start, even after adding a lot of fuel to the map. I swapped the resistors for 5ohm 5 watt units, nearly doubled the fuel at low rpm and the car started right up. If you are using 10ohm resistors I would swap them for 5, 4, or even 3ohm units before doing anything else. A little more info on resistors: https://www.rx7club.com/showthread.p...light=resistor FWIW CMonakar=CCarlisi

im using 7.5ohms at 25watts. this is specified by ray wilson. there is no problems with the resistance the injectors tested bare and backprobed and work the same so resistance is not an issue. thanks for the help though,every thing helps at this point

Go back and click on the link Chris gave you, and read post #6.

ray says thats what he uses on all of his cars at pfs... so i dont get it, why would he recommend something that would not work? not arguing with you guys just trying to save my self the headache of splicing new resistors in and ughhhh.... doing all of that with the engine in the car. should i just try deflooding the car completely tomorrow and starting again? i just cant handle having to order yet another part.

yeah spark like a ****! im going to try to sneak out from the family today and run over to my shop and deflood it. and i believe someone saying that each fc edit program has a different preloaded base "default" map. is this true? i believe im running version 1.090. anyone wanna hook a brotha up with the newest version.... mono4lamar@hotmail.com

HAHA! got some good and bad news! bad news is my primary rail was leaking out of the top where the front rotor injector top goes in! that wont help the front rotor fire the good news is that i believe this was my whole problem. when i would pull the front rotor L and T plugs they would never have any smell of fuel. pretty much my front rotor never ever got any fuel cause of this leak!
RICH did you do anything specific to aid in sealing? im getting pretty pissed at this point and might dab a tiney tiney bit of gasket sealant around the 0-ring. i hated how they fit in the block kg should have machined the holes in the rail a little further apart. they seem to make the injectors taper together! anyone have any tips tricks to helping top feed injectors seal better? PLEASE PLEASE PLEASE HELP
