i have a 92 prelude s i just bought not running
it doesnt have a spark
so far i changed the dizzy, main relay, ecu (all off a working car)
ive been searching for broken wires, i removed an autostart that was in there
i just cant seem to figure it out, any ideas?
the fuel pump is working, timing belt isnt broke

 

anyone?

 

Have you checked to see if there is power going to the ignition coil?

 

Check fuse #4 in the underdash fuseblock. Had this problem as well, turned out the fuse was blown, it supplies power to the main relay, which sends a signal to the cpu to send spark.

If the fuse is not blown, take the ignition module to an Auto parts store and have them test it.

Good luck!!

 

is the timing off?

 

there is power at the coil, i did check the fuses, but ill check again tomorrow, maybe i missed something... i hope, lol, i dont know if the timing is off, honestly i never checked it because i assumed there would still be a spark if the rotor button was turning..

 

how do you know theres power to the coil?
i had to run a wire from my fusebox under my dash to the coil to get it to get power to the coil so i can get spark
Note - 92 prelude with f22b1

 

Is there an injector pulse?

 

i took the cap off and checked with a volt meter and it had 12 volts at the coil, yes there is an injector pulse

 

has anyone ever had any problems with wires grounding out through the firewall or anywhere else on there car? could that be something to look for?

 

the ground on the battery tray, be aware of because my car wouldnt start because of this

 

i was thinking about this question "is the timing off?" and if it was far enough off that when the piston was at TDC to send the spark and the rotor button wasnt touching a contact that could cause it not to spark right? now.... if that actually were the case that the timing jumped that far, would there be damage to the head or anything?

 

not timing... its dead on...

 

check all ur grounds....especially the one on the thermostat housing.

 

all the grounds are good

 

does it just tick when you try to turn your car on? or what exactly does it do?

 

FIXED!!!!

there was a wire that rubbed through the harness behind the engine (under the intake manifold) and my dizzy wasnt working right for some reason, im assuming it was the wire because i changed the dizzy before with a working one and it did nothing...

Glad you got it fixed, I'm having an intermittent problem similar to yours.

How did you get access to the wire that had rubbed through the harness below the IM? Do you have a picture? I'd like to check and see if this could also be my problem.

Thanks

 

ill try to take a pic, but i was just in the process of halling out the engine wire harness when i noticed the wire wasnt connected into the bracket under the manifold and it just rubbed on the bracket and into a wire, so the computer was probably just grounding out through there, i could see it from the passenger side, a few inches back from the thermostat housing
