just did a mpfi swap from dpfi.. car starts and runs but misses very bad.. tried swappin injectors.. firing order in a manual is different from the firing order that i had on the dual point.. when i chaged it like the manual said it wouldnt start at all.. im running out of ideas.. any help will be appreciated thanks

see if thats your correct firing order first...then post back...

 

yea thats right

 

different distributor? clean the points at least? do you get spark to each as you should?

 

yea.. new ignition coil, cap, rotor button, wires and plugs

 

what engine?

 

d15b2 with d16a6 head

 

check your wiring...harness (both sides engine and ecu side)

 

yea the guy who did it forgot 2 wires and he fixed that and it actually starts.. but it takes a min 2 get it to start.. so im thinkin maybe the number 1 injector idnt working.. idk.. iv been messing with this thing for 3 days

 

personally with as much as it sucks it is pretty quick and easy to repin a wire especially the injector...can't hurt to try - I'd just go over them all - could have a wire not connected fully or something

 

well we swapped the pins last night.. even tried swapping around the injector clips... its not throwing any codes, which is a good thing lol.. i think were gona start over again n make sure all the wiring is correct.. thats the only thing i can think of..

 

i had someone say that since the motor has been sitting for a while to just let it run and it should get better.. what do u guys think?
