Hi, guys i just put a in a reman engine in to my car. The engine has been street ported and has 3mm apex seals. Full 3in turbo back exhaust. The turbos are no longer sequential they are now non-sequential. intakes and a power fc. The fuel mods are as follow i have 550cc primarie and 1600cc secondary with an SX fuel pressure regulator. Now heres the problem. The car starts up for like a second then dies. At first i thought it was the base map but i checked it and the guy that i sent it to did every thing right. The shop says that my 550cc are flooding the engine. It didnt do this before. i talk to some people at nopi nationals this weekend that had FD's and one of the guys siad that the injector O-RING my be pinched or broken. I havent checked that out and is that statement really true?
HE also told me that i might have gotten two wires that go to the crank angle sensor might be backwards or switched and that i should have a look at them. If you know how to fix my problem.. please post. thank you!

 

If your injector o-rings are pinched you night not be getting any flow in the engine, which might be why it suddenly dies upon startup. Take a look at it and let me know what happens

 

did you check to see that your fuel pump still werks?

 

I have a new fuel pump installed and it still does it so i m going to check the o-rings on the 550 injectors. but if thats not it what else can it be?

 

Are the primary injector diffusers okay? they are these litttle funky plastic bits that fit in the injector slots on the block underneath thick o-rings. From what the Turrentine video says, if these are broken, missing, or incorrectly installed, the motor will flood. I broke both of mine while pulling the motor and had to order new ones from Mazda, like $28 for the pair. If you didn't put new ones or your old ones in while swapping the motor, I'm willing to bet this is your problem. Good luck, Josh

 

So let me get this straight you brought the car to a shop to have this motor and other items installed and you picked up the car knowing it wouldnt start?

 

no the car is still at the shop. By the way the shop checked the o-rings and they siad it was fine ill tell them to check the diffusers.

 

1. never is a good thing to get info on the internet to realy to a shop so they can fix a prob

anyway so the car starts and stalls repetedly? you do not have to unflood it between starts? did they set the base fuel pressure the right way with the hose off? what is the base press?
