staright to the point . I just installed a bult motor built bottom end oversized vavles and walbro 255 fuel pump aem fuel rail aeromotive fpr. i got the car started with my crower cam shafts in but the car had no throttle responce i had to have the tb wide open just to get a week idle when i let go of the tb motor choked out. figure i didn't have the right degree for the cams so took them out and put stock ones back in. Well the problem is i have a pretty strong spark coming form my msd ing so i think im good there, i have plenty of fuel b/c i can smell it even when i turn the fpr all the way down. I not sure if i need avavle adjustemnt b/c it seem like my a/f ratio just isn't right to get it to turn over i check and searched everything possible im running out of ideas of what it could be.

only other thing i can think of is change out my 440 for stock to cut back from dropping so much fuel

do a vavle adjustment b/c since i had vavle work done they might not of set the vavle right.

that the only conclusion i have so far need help and ideas???


resleeved block
forged internals
port and polished head
msd ing and blaster coil
walbro fuel pump 440 rc injectors aem fuel rail

just running close to stock till motor breaks in

 

what is your Air/Fuel ratio? I'm sure you are running a wideband....

 

what are you tuning with?

 

no wideband. running hondata s300

 

get a wideband before you wash out the rings on your new engine

 

or take it to a tuner right now

 

Are you using the same map as you were before installing the 440 injectors?

 

no had the turner tune for 440 injectors and bigger ignition

 

Are you sure your timing belt and distributer are aligned properly?

 

so it ran before you replaced the engine?

 

yeah had this one bulit for boost

 

Check firing order make sure your spark plugs are in the right order.
Make sure your sensors are plugged into the sensor the fan switch, iavc?, tw are all the same size and will plug in.
Valve adjustment.
Spark timing.
Cam timing.
Wtf? You put 240cc injectors on a 450cc base map? That’s not going to work.
Check your spark plug gap.
Make sure there is not restriction in your fuel line, once I did a b16 swap into a ef and left the original banjo bolt on and bolted it to the b16 fuel rail(it physically fit). It restricted the fuel so much the car would start and then die a sec later.

 

thanks for the ideas and i tried them all still no go it at the tuners now thanks to all
