I recently installed a blitz fmic, nippondenso fuel pump, and 1300cc injectors (in the stock secondary fuel rail). After i got everything in, i set the power fc commander to 1300cc's by changing the lag time to +0.16ms and the Q-Sc to 1300. when i tried to start the car, it idled like complete crap. The rpms were bouncing rapedly between 500 and 900 and a LOT of smoke was shooting out the back nonstop. today i took the injectors out to inpect the o-rings and everything looked fine. I put everything back together and when i started the car with the clutch in and in first gear, it idle'd just a little bit better, but it stalled right when i put it in nuetral and let my foot off the clutch. after that it wouldnt start, it sounds like it starts for about a half of a second, but then dies right away. does anyone have any idea's? please help me!
thanks,
Craig

P.S. Please dont move this to the power fc forum, i posted in there before and didnt get any help

 

bump, please i really dont want to have to take her to a shop does anyone have any ideas what could be wrong?

 

Are you sure the engine's getting fuel? It would be the first thing I would check, given that you just replaced the fuel pump....

 

Sounds like you're flooding so have you actually tested your secondary fuel rail under pressure for leaks? A mashed o-ring or bad injector will drip gas into the LIM. The secondaries don't even kick in until you're at a certain RPM and engine load so they shouldn't be active at idle. Also if you're using Bosch injectors don't those require a resistor of some sort? Also make sure your MAP sensor is connected and maybe check your TPS to see if it is operating correctly.

 

i have checked the map sensor and its connected right. i remember the very first time i tried to start the car after i installed these things, something under the UIM was clicking a lot but it stoped after about 30 seconds and never did it again. im using nippondenso injectors (got my 850cc injectors bored out to 1300cc)

 

Id start by putting the old injectors back in to see if its gonna run ok with them

 

**** just noticed,,,you bored out the old ones,,,,
