ok the motor is getting spark and I hear it pumping fuel...I bought a harness coverted from dpfi to mpfi from Carlos on here and I cant get car to start running...I am getting code 20 but I dont think that has anything to do with car starting does it???

 

if youv got a 90-91 civic with a 88-89 ecu then you'll get code 20 all the time because 88-89 had an electronic load detector in the underhood fuse box. 90-91 doesnt have it.. doesnt effect anything , mine has code 20 because of this. however if your car is 88-89 and has the same ecu then im not sure if it would cause the car not to start .

Yup, my 91 std. has it. I was like WTF when I looked up the code.

 

good start so far....work on hondas all the time but the simple firing order screwed with my head.... i went from left to right 1-2-3-4 instead of 4-3-2-1 on head...silly mistake but will fix it in morning dont wanna get hands dirty before my lady gets here or she kill me haha

 

What kind of spark plug wires are you using? Mine won't let me, they are length specific.

Or did you mix it up on the dizzy?

 

yeah probly i dizzy mistake. i did the same thing when i did my first swap. im impatient tho so right away i sold the zc i had in it for a t3/t4 zs gayness turbo and a 800w kanwood amp. but ended up with a b16 so all is good.

 

screwed it up on dizzy but its dark out and figure it out after work tomorrow and will let everyone know...cross fingers...just the car my friend bought someone did a shade tree mechanic wire job on itttt

 

Look for a random green/red wire to put back into b19 to clear your code... Let us know more info soon

 

ryan I think that wire is just sitting there, I will look into that tomorrow thanks

 

update got car to start but sounds like its miss firing and doesnt want to stay running...need help please

Timing? Sure the firing order is correct? Are all the injectors working?

 

ok solved it all one plug is in wrong on back of manifold...now y does my TB keep sticking on me i clean it out and lubed it and still sticks....like I push gas in and let off it will stick at about 1400 rpms....also tach is not work in car after the mpfi swap....any idea why that might be???

My throttle did this also.

I had to adjust the cable some more. Play with the two nuts on the cable until you find the right place. Mine's perfect now.

Lol

 

haha...but ya we tried that...I just try to adjust that lil needle tomorrow on bottom of the tb if nothing happens I just gonna have to get a diff tb and go from there

 

the throttle stop? if you get it too far screwed in the throttle plate goes past closed to open and when you step on it it sticks. take the cable off and look at the plate and make sure its closing all the way and not past closing . make sure it opens freely . if youve adjusted that throttle stop your tps sensor will be off also. throttle stop is not supposed to be adjusted. but if it is you could use a digital multi meter to check the tps to see if its set right.

Just something that happened to me with a used throttle body once that someone had dicked around with before i got it.
