1987 Civic / no spark after rebuilt engine installed
I am looking at a car for a guy who put a rebuilt engine ( 1500cc )in a 87 civic sedan. There is absolutely no spark at the coil. All the wires are plugged in and everything seems grounded where it has to go. I have swapped out distibutors, ignitors, coils, and I am up in arms. Is there a crank sensor on this car that anyone could tell me about? It is getting power from the ign when the ignition is on, but no power to the coil when it cranks. There is a blue wire on one of the two plugs that is next to a constant. should this show power when the key is cranking?? Sorry if I dont make sense, please help

check the coil with a multimeter, and check the wiring for bad wires. also is it not getting spark after the coil? hold the coil wire close to a ground and crank if you get a spark its not the coil

Re: 1987 Civic / no spark after rebuilt engine installed
There is power going into the coil when the key is on ACC. When the engine cranks, there should be another wire throwing power to tell it when to spark right? I have one wire that has no power on either ACC or when cranking. No spark at the coil.

Re: 1987 Civic / no spark after rebuilt engine installed
Is there a crank sensor somewhere that tells the coil when to fire?

When it cranks, one of the powered wires should be getting a neg pulse? I did not know that. The igniter is in the distibutor, isnt it? Thanks for all your help guys!!

Igniter
Is the igniter the little black thing that spins in the distributor?

Re: 1987 Civic / no spark after rebuilt engine installed
ummmm nope...its the thing under it....the thing you say is the reluctor(somthing like that...)its under that....its a little black box with 2 plug type cables attached to it......well it also depends on what type of distributor it is... if its a toyo denso or a hitachi... but in this case yours is a hitachi...
.............  ... o what ever! you get the point...dont wana bore you...
