now that you looked....theres no motor. my buddies crx has no spark. has new ecu,and new distributor. there is no spark what could it be?? car is a 91 crx si

Take the cap off the dizzy, and turn the roater 15 degrees. it should spark

 

the car died while he was driving.... we replaced the ecu with a known working one and also a new dizzy. would the main relay make it not spark??

yeah, go cheep first, and replace that main relay to see what happenes
if not, check grounds, if its not a good ground. your valve cover.
and check if theres any loose connections on your ecu

 

he lives about 500 miles away so.... will the main relay cause no spark tho?? i know it controls the fuel pump..... all connections seem good, ill have him check the valve cover ground, he did clean the thermostat ground cuz i know thats for the ecu..... any suggestions are appreciated.

The relay, could have a bad connection. check fuses.
here is a good way to check for spark. be careful.
take the spark plug out of cylineder 1. and put the plug wire on the spark plug.
and hold the wire with your hands, and rest the threds of the plug on the the edge of the valve cover. and have someone try to start the car, and if it is, throughing sparks. you will be able to clearly see them.

 

It could be a bounch of different things that could make the car not run. Do a search and you will be suprised at how much info. can be found.

Things to check:
Ignition switch
Timing Belt
Main relay (Controls main ignition and fuel pump)

Among other things. You need to provide more info if you want a better answer.

 

i have been searching and it says ecu, distributor and they are both out. we know it has no spark by the way.... k ill have him check them things. thx guys

check and see if the ecu is throwing codes. if so. lookem up boi

 

see if fuse 14 is blown

 

he said he checked all fuses and i asked him many times to make sure thx tho

 

got it, it was the main realy thx guys

So just fixing the main relay got your spark back? I'm workin on this 4-door right now that's givin me a no-spark problem too but having a pickle trying to diagnose the bad part/connection...

 

Yup! FTW!
