Carb'd 4AGE on Hyperpak ignition no spark problem
Hi guys i have a bigport 4AGE engine from a AW11 MR2 on carbs with a Hyperpak ignition control unit to run the stock distributor.
I am unable to get the engine to start due to no spark, well i say no spark i actually get one weak spark at the very first crank of the engine and then nothing at all when i continue to crank the engine. I dont always get the spark at the first crank of the engine either, its a bit intermittent. I have double checked the wiring against the diagram that came with the kit and the ignition coil is brand new. I'm at a loss with what is wrong with it, my only thoughts are that the distributor is causing my problems or the hyperpak unit itself. ![]() Are the distributors known to give ignition faults or are they fairly reliable? Any help with this would be most appreciated. ![]() ![]() |

Distributors are fairly reliable I would say. Sounds like it's not getting the right signal, or the signal isnt clean enough.

Sounds just like my ignition problem after my recent engine rebuild!
![]() I´m not running fancy carbs with aftermarket parts, but it just turned out the the ignition coil somehow lost it´s earth, wireing and coil stayed untouched all the time!!! I searched weeks, changed coil/ distributors/ leads plugs, read diagnois codes. Nothing. Got a tip, to run a direkt wire from neg. Terminal to housing and got sparks again! Worth a try I guess??? 1979 Toyota Corolla KE35 1983 Toyota Corolla AE86 1985 Toyota Corolla AE86 |

Here is a scan of the wiring diagram for the hyperpak, i have wired everything as per diagram/instructions.
![]() The yellow wire from the hyperpak on the diagram is not visable but it connects to the (-) side of the ignition coil. ![]() |

No I've not had a single reply to any of the emails I've sent, I'm not really that suprised after the hassel i had getting the thing in the first place. ![]() I've given up on it now and decided to go down the mappable Megajolt/Edis trigger wheel route. ![]() |

Someone else already has it to do just that/copy it. Thats if they can get through all the epoxy resin that it is covered in!
