try just spraying starter fluid(wd40,brakecleaner,ect) see if it fires up and is the pump priming

Re: mpfi swap problems.
 

k be right back with results.

Re: mpfi swap problems.
 

the pump primes but i still dont think the injectors are firing. what is the light blue wire for???? thats what is killing me to find out.

Re: mpfi swap problems.
 

nothing happened when you sprayed stuff in the trottle body, my box has 4 redand black and a yellow black, whats your have and what car is thisd on

Re: mpfi swap problems.
 

same thing as yours. its in a std 91 civic hb. the motor is out of a crx si. was in another civic hb and ran like ass. its form a d16a6 so i know it will worky, just getting it to is a bitch.

Re: mpfi swap problems.
 

so theres a weres this blue wire go back to? do you have all the wire i do plus a blue one from the box

Re: mpfi swap problems.
 

i got a blue one to from the box. is it a power wire or some ----???? i havent found anyting on it yet.

Re: mpfi swap problems.
 

is it light blue with a yellow tracer, so you have 6 wires from the box to the female part of plug, you got a camra so i can see what your talking about

Re: mpfi swap problems.
 

exaclty man, you jave got it on the spot. i dont have a digi right now.but it is the 6 wire rect. plug like u are saying.

Re: mpfi swap problems.
 

were did you get teh box from mine has a spot for a 6th one but just a rubber plug in it

Re: mpfi swap problems.
 

it was on the motors wire harness but its not looking like it was ever connected.

Re: mpfi swap problems.
 

ok im a ------ idiot. i was reading through yours and i found that it was the gorund on the water neck. it runs but it sounds like ass, like its not running on all cylinders. waht could i check next. or does it sound different after the swap like its rougher and louder??
edit: i also think that i have the wires on the distibutor in the wrong location. may that also be the cause.

Re: mpfi swap problems.
 

does it have a mis and shake
or just sounds load

Re: mpfi swap problems.
 

i just checked my manual i bought and i had the damn wires on wrong. now im waiting for my battery to charge with the battery charger. and i also advanced the timing a bit, because i had it in no mans land. get it. lol..... :S

Re: mpfi swap problems.
 

good luck im still stuck with no spark and fuel pump not working but i got the starter cranking by the key again so thats a plus

Re: mpfi swap problems.
 

i would suggest you look at your wiring very carefully on your dizzy. i made sure that was correct the first time by reading many different diagrams and then asking here to see if they were right. i was told to match all the colored wires together, oh and make sure that the two white wires are going to the correct whites on the plug. that will also cause no spark as what i was told. then connect your c1 & c2 wires to the right wires. mine worked on the first fire once it started, but i was a dipshit and put the plugs on in the wrong firing order so thats why it sounded fucked up.lol :S good luck hope that helps for the spark issue.

Re: mpfi swap problems.
 

ok its running but im throwing 3 codes:
code 7-throttle angle
code 10- air intake temp.
and code 14-eacv.

the tps is fucked on the intake. can i take the one fron the d15b1's intake and put it on the d16a6's intake??? if i can i just wire it up like it is supposed to be once i do the swap?

air intake i have no clueon how to fix.

and i have the eacv hooked up, so why is it throwing the code for it??

help me know please. ???
