Hey guys still trying to get the celica to start, and now I’m dealing with a no spark. Fuel and compression are okay now, and i get spark in cylinders 2&3, but 1&4 only gets spark maybe 1/10th of the time. I have the 4 pin style dizzy shown here.
![]() I took a video and put it in slow mo, and sure enough the coil only sparks on cylinders 2&3 ![]() It seems like I’m missing half the signal, but I only have a single pickup inside the distributor, upon digging a bit deeper I noticed the condenser looked a bit melty: ![]() Ordered a new one as well as an OEM rotor, since they’re cheap and the aftermarket ones are pretty disappointing. Am I wasting time on the condenser? Any idea what may cause the intermittent spark? I don’t see any kind of igniter, And I’ve tried a couple coils now. |

So I found the igniter and measured the voltage going to the harness, (prong number - Leads(battery/prong) - voltage)
1- B+/P- - 7.8v 2- B+/P- - 7.5v 3- B-/P+ - 12.8v 4- B+/P- - 12.5v 5- B-/P+ - 12.8v Can I get a link to that OBD-II diagram? I’ll replace the igniter if I have to, but I’m not sure if that’s the issue since the car ran before I did the overhaul and now I’m getting intermittent spark. I figured maybe a connector isn’t seated right and maybe that’s my issue but I did so much while everything was apart it’s hard to tell exactly what’s wrong 😅. I read that these are supposed to have 5v reference signals, is 7.5v high enough to cook the igniter you think? |
