my built and boost crx wont start


i have

no check engine codes/light
i do have fuel
spark
compression
everything hooked up
timing on

the car cranks over but it will like hiccup but it wont start. if i let it sit for a while then come back and try it will crank once like it wants to start but not after that, i have no idea what it could be no enough or to much fuel? all this occurred after it was runnig like **** cuz the alt was so bad and the battery was dead as hell so i got both new started right up went back in the morning to drive it and it started and ran like *** then died.



anyone with help please chime in.

 

i need help

 

check fuel PRESSURE

 

going to get a gauge tomorrow

 

got a different dizzy and its still running like ****. im running super rich and i pulled my plugs and there all wet in gas. i dont understand how i could be rich all of a sudden a pouring so much gas

can anyone help

 

what size injectors do you have? is your ecu chipped?

 

blue top 450s and yes its chipped

 

something isnt right then, who chipped your ecu, who did the fuel map changes, whats the fuel pressure at currently, what fuel pump are you using. need some more info.

 

did you get a basemap?

 

ecu was already chipped. i used my buddy old map for start up etc til it gets tuned. stock pump

 

if its built and boosted your gonna need a bigger fuel pump

 

i have one not installed. im getting to much fuel right now

 

False ^

I'm currently running stock fuel pump. With a B&M fpr, it will make 60 psi. That's plenty for my DSM 450s on my CRVTEC at 8 psi. I've got a good tune and room to up the boost before maxing out the duty cycle. Just sayin'

 

x2 you dont need a bigger pump til you up the psi which im not doing at the moment

i just dont get how im running rich and have all this gas

 

my bad i thought that maybe it sounded like your pressure was too low but if your running rich then thats deffinitely not it lol. did you try getting a basemap made for your setup? that might help to make it run decent till you get it tuned..

 

hey i try the main relay cause my car is all stock with a single zc and it does that from time to time i check every thing and every thing was good spark fuel dizzy were all good i pulled the main relay down taped it with a screw driver and the car turned over im still using the same one relay and i still have to hit it from time to time i might be wrong but it sounds like it let me know

 

ive hit the main relay twice with a soldering gun so it should be good. but im going to get a different basemap

 

hit it then try and turn the car over to see if it starts if that dont work get the basemap done

 

it starts now guys it just really rich and lots of gas! and running like ****

 

its most likely running rich because of the tune..

 

yea i got a different basemap and its still running like **** idk it ran great so idk how its now not running good

 

like i just went a started it and came inside and my girlfriend said i smell so bad like gas from exhaust fumes

 

if i pull the chip out of my ecu and then the key fwd to the on position i was told i can check my codes is that correct?

 

nvm i answered my pwn question

 

Sounds like car is running rich. Pull the plugs out and check you should be able to tell.
