My car is not getting spark! The other day I did a compression test on it and it tested fine, all cylinders were around 170psi. I decided to change the spark plugs since they were old. I replaced them then tried to start the car and it wouldn't start. I researched and found out that I was suppose to pull the fuel pump fuse or disconnect the dizzy but i did neither, stupid me. I've let my car sit over night to air out. I'm getting fuel on my plugs but i am not getting spark. I think its either the plug wires or the dizzy. Any ideas on where i could of messed something up?

Car is a 94 civic with a b18b. I am using MSD 8.5mm spark plug wires.

 

check the dizzy if it got fried

 

I bought the dizzy brand new but anyways i checked it and it looks fine, everything pretty clean no residue. What am i looking for or how do i test it to check if its working properly?

 

so you have spark now right? did you plug up to the right firing order?

 

I dont have spark. The firing order is right

 

do you have a tach? if so does it move when cranking? if yes try a new coil in the dizzy . if no the odd's are you fried your ignitor. all that voltage has to go somewhere. good luck

 

The tach does not move at all. When you say ignitor do you mean the part inside the distributor?

 

ya, try to barrow from somebody car that you know is working

 

A lot of times you can take apart the distributor and see fried electronics or even smell the separate pieces to see if there's burned plastic.
As Hondatherdm posted, it helps to borrow working parts to eliminate them as the issue.

 

Exactly. And since you didn't have the spark plugs hooked up for the voltage to jump across the gap (or the distributor unplugged), it found another way to ground and fried your coil and/or ignitor in the process. The tach takes it input from the ignitor (which is why canadaek asked about that) and with you saying it's not moving while cranking, it's not hard to see where the problem probably is.

 

not to bring up a dead thread, but should the tach jump every time you crank? i have a car that wont start that has good spark on all 4 cylinders but my tach isn't jumping at all

If you did not unplug your coil you could have fried it. Mostly people over look this when compression testing. You should always pull your fuel pump fuse and unhook your coil. I have done this before too on a eclipse and fried my coil pack it haapens. The coil is operating when you are turning over the motor, and if it has nothing to ground it like a spark plug, it will produce more spark and end up killing the coil.

 

well im still not getting spark , the fuel pump is turning on. I checked inside my dizzy, replaced the ignitor with a newer one, tried a different ecu but still no spark...

Any other ideas out there or someone can donate a bseries dizzy..

 

You most likely blew the coil in the distributor because you did not pull the ECU fuse when you did the compression test.
