I have 91 civic that I recently did an auto to manual and b swap too car was starting but needed gas to stay running only codes were map and ckp so I changed the dizzy with brand new and fixed the map code but now I have no spark? What could be the problem?

 

Also still no spark if I try putting the old dizzy with bad ckp back on?

 

Anything?

 

Check your engine harness ground on the thermostat housing... make sure the surface is scraped clean and the bolt is tight.

 

Grounds look good not crusty or anything like that

 

Checked grounds to be sure they're tight and clean and I did test my ecu on a buddies car

 

Anymore ideas guys haven't had a chance to work on it for a bit but idk what to check now

 

Went and cleaned up the grounds to be sure and put new dizzy back in still just cranks assuming no spark still but haven't had anyone with me to turn it over while I check. Any suggestions?

 

Tested dizzy off car with multimeter and everything came up good so no idea where to go from here ecu gets power and worked in another car plugs and wires are new and grounds are clean(tried adding an extra didn't help). What wires should all have power at dizzy clip?

 

diag > throwing parts at it.

be certain that spark is your issue. you can buy a spark tester. sit in the car and see if tester lights up while you crank

 

Absolutely positive there is no spark from the plug, plug wires, or the dizzy itself. I've had multiple people look at it and try to diagnose this but all comes back to dizzy which is new and has been tested with multimeter and everything comes up good. I don't have the funds to get a new dizzy or anyone with obd0 willing to try it in there's a buddy did test my ecu before he went out of town and it ran his car fine. Just didn't have anyone there to help verify it was still no spark at that time but has been checked
