SO i did a mini me swawp on it..
im getting spark
but no fuel..
i get it up to the fuel rail nut not out of the injectors
im running a resistor box used 2 different of injectors.(size both still low impedance)
i dont know why im not gettin them to fire.
i was getting power out of the resistor box.
i dont have dmm only a test light atm so i dont know exact volts or amps
coming out of it
thank you guys for any help

Details needed.

What ECU?

What engine?

What is the need for a resistor box? This is probably the source of the problem.

Return everything to stock. If the car is no longer turbocharged there is no longer a need to run those parts.

momo253

i have a p28
d15b7/z6 head
i have low impedance injectors so i need to run it
i was wired in the stock harness but im using a vtec harness rather then
stock do you think this could be a problem?

they is no point to make mymcar stock again?
technically that would mean no vtec head because that wasnt stock
just saying

has anyone used the rywire engine harness before for a mini me swap?
or know if it would work
the wire tucked one not just the sub harness

thanks

Stock as in OEM parts. There is no need to run low impedance injectors with a resistor box OR any chipped ECU on a mini me. ANY turbo parts should be removed and replace with "regular" N/A parts.

Former User

As mentioned, return the injectors and their wiring to stock for the P28 ECU and then go from there.

momo253

alright ill find some oem injectors for it
should i find a new p28? mine did smell or look fried
im thinking about buying the rywire harness because mine is pretty bad
do you think that would work?
i know all these work but the ecu and the resistor box could be fried now
because it was all on there before the mini me swap
i wouldnt have any problems from it being the vtec harness right?
i have one connector that is just capped off.
i belive its grounds it has only yellow with a black tracer wires running in to it
it is behind the drivers side strut tower and right infront of the firewall
i can get pictures tomorrow if you guys are un sure what im talking about
should it be wired in or is that not a problem.
thanks again

momo253

update going to get z6 injectors this saturday
along with a new cltuch ex/si tranny and throw out bearing
so when it runs i can get it to run good

momo253

alright got the injectors still dont fire...
checking tomorrow to see if i get power to each clip.
i have a few wires under the dash none to the pgmfi relay but they are unpluged/free
my battery is dead so i could not have enough amps or volts to fire the injectors so i guess we will find out tomorrow or wendesday whenever i have time
i dont know what the problem is anymore im not the best wiring its either the power or control of it. pretty sure its power because my ecu works in other cars so the control from there work still the transistor are working in it so im not sure what the problem is gonna look ovver myh ground i know g101 is the ground for it. it could be loose but not really bad enough to add resistance if any one has any imput has had this happen or know why its happening it would be great.
im almost leaning towards a rywire harness so i know its not the harness.
does anyone know if i have to change any pins on my hanress that goes in to the ecu when i change my hanress in the engine bay to a z6 harness that could be the problem if i need to. if so let me know and ill fix it
thanks in advance for any info and help
ps i am using a vtec harness so i didnt wiring in the vtec my self so i dont know if i need to repin places or not thanks again

momo253

or should i find a stock sedan harness for the b7 and wire in the vtec solenoid etc?

momo253

anybody have input

Former User

You owe us information - Battery charged? Starter cranking? Voltage at clips? CEL codes? Fuel pump prime? Spark at plugs?

momo253

Charging it and no cels going to test the clips tomorrow am with fresh charged battery starter cranks and yes I get spark any more info needed can be provide when I'm out of class

momo253

Fuel pump primes nownew pgfmi relay 15 amp fuse is good. Also

Former User

Will the engine start with starting fluid?
Does the CEL work?

momo253

havent tried starting fluid..
but my 15 amp fuse keeps blowning
gonna check for shorts to grounds tomorrow morrnig i wasnt getting any voltage to my clips but then i checked the fuse again and it was blown...
but a 25 amp in it for right now but going to get more 15s tomorrow and electrical tape since i have open wires above my fuel rail that could have been shorting to it that i didnt even think of as i was testing it since i just got out of ems class.
i am running a z6 harness right now i dont know if that could be causing a problem or not...
but ill have my b7 harness down here with in a week if that would make a difference im going to check the clips again in the am when i have more time.
i get fuel althe way to my fuel rail when the fuse isnt blown so i know its my injectors not firing the arent wet at all when i pull them out either
i know my info is quite bad at them moment.
i will be testing them again tomorrow. i didnt get any signal with the node probe or power when using the test light on the source wires. i know the ecu works because i used it in a friends car last week when this problem was starting.
so..
yes my fuel pump primes when the fuse isnt blown
i am getting spark
it is off time by a bit but i also know my injectors arent firing i could pick up some starter fluid tomorrow also and im sure it will start off that.

Former User

1) Fix the electrical short - solder and heat shrink wrap all wire splices. Do it right.

2) What do you mean it's off time?

3)

momo253

im not going to solder it till its all right and working i have a solder gun and heat shrink but i want it all running first. so if i need to change back to my b7 harness i can easily
and the block its self there like 3-5 degrees off from both being tdc when the crank or head is at tdc
the cel does work it light up etc when i have the key on.
i going out right before class to try the clip again so ill post an update when i get to class on the results.
thanks again

Do your spark plugs fire in succession? Have you tried putting the injectors outside of the manifold and turning the motor over? you said you put stock injectors back in there, but did you remove the resistor box? and the box is wired into the harness, how is it wired in there? because its possible that the wires got loose or are not making the proper contact.

momo253

yes my spark plugs fire right. right firing order.
i took the resistor box out right away.
they are just ghetto spliced right now till i get themto fire they making contact though i know current ill flow when i get them to fire
yes ive had them out. ive had the fuel rail unbolt just resting on the intake manifold
where do you think that they got loose or couldnt be making contact at?
DOES ANYONE KNOW IF THE PROBLEM COULD BE FROM THE Z6 HARNESS OR NOT IVE TRIED TO SEARCH ABOUT MINI ME SWAPS USING Z6 HARNESS'S BUT INHAVENT SEEN ANYONE DO IT OR A WRITE UP ON IT

momo253

Alright I'm gettng power to the clips but no control to make them fire which means the "colored" wires aren't. Getting signal from the ecu. The yellow with black tracers are getting power through them. Where could problems happen on the control side for it to not get a signal from the ecu to fire them.I was using the node probe on the and a test light. My friend has a multimeter so I can check how much voltage and current I'm getting through them.. if any one has ideas or knows where my control side could be having prblems it would be great. Thanks once again.

Jimster480

im not 100% sure that they should be getting voltage, i thought that one was voltage and the other was a "signal" wire. And have you checked the little clip with the cap-plug for the injectors, i have seen water get in there or the cap get damaged and cause the injectors to not work. And the Z6 harness shouldn't be a problem, my friend used one on his mini-me setup. its essentially the same harness just with Vtec added. Where did you get the harness from?

momo253

yes one should be signal but when the node probe is hokked up the it flashes when it gets the signal. I got it from my friend same person I got the head and everything from.
I know its not getting signal from the ecu but my ecu works
So its a wire problem to the ecu could I direct wire it to the ecu out of the harness?

momo253

another uodate got signal and power to injectors now. still wont fire up it wines as i crank it i can snap a video tomorrow i know it needs to be timed,
im going to do it tomorrow. if its off time badly enough it wont start right.
so im going to do that tomrrow re check my clips to double check that they are gettin signal.
tighten my battery cables and other grounds. to make sure they are secure
i also soldered my power wires to them to day
stupidly enough one of my connectors wasnt all the way tight...
just goes to show never trust anyone else with your car even if they are "helping"you haha
and just so you guys know im currently at wyotech in automotive so im not just some dumb kid ****ing with his honda's anymore... or as badly... haha

Former User

As you now have fuel to the cylinders, now check spark, mechanical timing, and compression.
