i did the dpfi - mpfi swap on my 90 civic dx. wired everything up correctly and it wont start. i tried switching the two white wires around and still no start. i am getting fuel but i dont think that i am getting spark. please help. thanks

 

did you switch the wires at the computer also are all of your connections good.

 

yes i did switch the wires at the computer. i will double check though just to make sure its the 2 wires for the fuel injectors (A3 and A7), and the two wires for the cylinder sensor (C1 and C2). the wires i cut at C1 and C2 i ran to pins B10 and B12. and ran C1 and C2 to the distributor.

 

just checked everything over and everything is wired up correctly. im starting to think that either the ignitor or the distributor is bad.

 

anyone have any ideas

 

i just did my mpfi swap last week..i would swap over your cap n rotor and even the coil from your dpfi dizzy..

 

im goin to try that today.. i'll let you kno what happens

 

i recently did the swap also, but im throwing codes 4 and 16. i'm hoping it is just shitty wiring. I am in the process of rewiring it all with new wires and solder.

I think the ignitor/distributor is a logical culprit. Do you have access to a working one? Perhaps from a friend?

 

im going to swap it with the one from the dx dizzy and see if thats it.

 

you think you have spark? how did you come to this conclusion.. just kinda hoped you had spark and didnt check.. pull a plug wire off the distributor wile someone cranks the motor..

 

okay i got it started. i swapped out the ignitor, the cap and rotor and it fired right up. but everytime i try to give it gas it cuts off. i am throwing a code 14 tho for the iacv. i have to check to see if i have the right connector on there or not. could that be why it shuts off when i give it gas?

 

solved that issue as well. just had the wrong connector on there. but now it sputters when quickly give it gas (idles then pedal to the floor). any suggestions or clues? thanks

 

bump...... i have the same stutter problem
