FUCKING no spark
 

i have an 89 dx crx that i did a mpfi swap on a while ago but it has never been started or ran since. Im using a 91 pm6 ecu that has not been chipped yet and have used 3 difference mpfi distributar's 2 known functionable. Im throwing codes 10 and 20. i know the motor is good . I just get absolutly no spark what so ever. i have no idea whats gone wrong plz help......... o and ive gone over the wiring a million times and i sodlered all connections

Re: FUCKING no spark
 

Bad main relay maybe? Try pullin the relay out from under the vent on the driver's side there and resolder all the connections on the back of the board. Alot of times this is why 88-91's don't start, or start intermitently. Worth a shot if nuthin else. :-\

is your sparkplugs fried?

Re: FUCKING no spark
 

the spark plugs were working in the other car and even when i put a brand new plug in there is absolutly no spark so i dont think its that..

Re: FUCKING no spark
 

have you tried the "2 white wire swap" on the dizzy, i know certain years require this

Re: FUCKING no spark
 

actually i havent i think/ hope thatsit i didnt think that caused complete loss of spark though i will def try any other ideas?

Re: FUCKING no spark
 

code 10 is air intake temp sensor
code 20 is electrical load

im guessing you didnt wire it right, check all your points on the ecu and make sure they working. if it ran before then its something that youve done in the wiring. check it with a good known write up.

Re: FUCKING no spark
 

what pionts should i specifically check on the ecu? like is there any that i can check at the ecu with a multimeter?

Re: FUCKING no spark
 

get the obd0 pinout and see which wire goes to what plug and pin. just search google its on there.

Re: FUCKING no spark
 

funny i did the swap two weeks ago and too throwing 10 and 20. i also have no spark. let me know what you find out. thanks

Re: FUCKING no spark
 

Ignore the electrical load code as I have never been able to get rid of it on my 90hatch with a MPFI swap.I too had some problems with no spark and i spent a while going over the distributor wiring until i found the problem.Good luck

Re: FUCKING no spark
 

ive found that all wiries dealing with the distributar are c1,c2,b10,b12 so im going to check those and also do the white wire switch in a matter of minutes and let u know what happens

Re: FUCKING no spark
 

yea i figured it out after 5+ months of not running and countless hours it turned out to be a mix up of b10and c1 (idk how) and the white wires on the dizzy THE BITCH IS ALIVE , o and i woke her back up with a tire popping burnout in my garage
