alright guyz hows it going im new here... but anyways lets get down to it... i just put a b18a1 swap in my 91 dx..
wiseco 9.8:1 comp pistons (forged)
eagle h beam rods (Forged)
king bearing set crank and rod
4-1 header
full exhaust in the mail
xs power intake manifold
and blah blah blah
anyway i had to do the dpfi to mpfi and thats whats giving me the hassle right now
the car ran fine before i swapped it... no issues at ALL!
may i mind you this is a 0bd0 set up
the fuel pump aint kicking on
but im getting spark
each injector when the car is on the "on posistion" gets no volts to it but when i try starting it, it jumps up to like 8.5 to 9volts (yes i have a resister box wired in)
yes i have all my grounds, the thermo stat one, the valve cover, the battery and chassis to tranny grounds they are all good...
i dont know what i coulda did wrong on my dpfi to mpfi swap
i took pins a1 a3 a5 and a7 snipped them and wired them to each corrosponding injector (had them marked and they are correct lol) i took the yellow/ black wire from the old injectors off the dx harness and wired that up to the resister box i swapped the c1 c2 with the b10 and b12 or what ever the crap that was, all i know that is not the issue
why isnt my pump kicking, why isnt anything working lol, the ecu (pr4) led light is off but when i tried pluggin up the pm6 i have from a zc the led was on
before you say hey there is a thing called goooooogle, well guess what i used it about a million times tryin to figure this **** out, all the people with the same problem solved them and never said what they did to fix it...

 

try swapping your fuel relay for a known good one, without being there to diagnose this problem would be interesting, because this is more a get down and dirty diagnosing situation.

I think the biggest problem of why it won't start though, is because your exhaust is in the mail!

 

Did you take the wire out of the driverside shocktower for the resistor box. Are you sure that your injectors are obd0 injectors.

 

yea they should be obd0 injecters due to the fact i bought the whole motor n tranny from a 91 integra... the integra was a running car...
what wire are you talkin about from the drivers side shock tower?

 

where is the fuel relay, theres like 30 relays under by the fuse box, i cant tell which one is which

 

what wire do you have going to the yellow/black wire on the resistor box

 

the 2 yellow/black ones from the actuall harness itself... i had them ran from the ecu but proved to be more of a problem
btw im not gettin spark no more either..

 

Are you gettin any cel also do you have any blown fuses
