Have fitted an '88 turbo to a '92 convertible. Car doesn't start. There is spark, fuel pressure at injector rail, power to the injectors (White/blue), but no signal from ECM (Blue). I suspect my ignorance of the igniter's function is the problem: I didn't transfer it from donor car. Can you help (Is this enough information?). Sincerely, Wimsey |

Sounds like a neat project, I'm sure some one will come along that knows, possibly Dallas or Starscream. |

assuming you swapped the harness and ECM PCM from the 1988 donor to the newer victim car ? if yes see the how to section regarding the testing of the CKP CMP what test equipment do you have ? |

I don't know much about these turbo geos, but it sounds like your problem is more rudimentary. Do you have everything grounded? Is there a ground wire on the bottom of the turbo manifold like there is with the N/A ones? |

Thanks for the swift replies. Mwebb: Regarding wiring, I pulled the entire loom from the donor car. It's having to blend the two looms that's taken the time. I have the most primitive testing equipment - a multimeter and a circuit-test lamp. I'll check the tech. site referred to. Starscream: The ECM is grounded (Black/blue and Black/green, I think) to the injection block. My ignorance is appalling: what does N/A refer to? The diagrams give N/A as the code for the O2 sensor wire. Does either of you know what actual colour code is used? Cheers. Wimsey |

N/A = Not Available but the color is white and it is inside a shielded cable , the 02 sensor signal wire is black the car has a separate Ignition control with an EST out put to the Fuel ECM the distributor has only 1 speed sensor , a CMP , AC signal generator the Fuel ECM knows engine RPM from the EST signal and MAY have some control of Ignition timing - IF it behaves like other GM systems of that time period . the system uses a KNOCK sensor the system uses a KNOCK sensor the system uses a KNOCK sensor the system uses a KNOCK sensor the system uses a KNOCK sensor this is a good thing - if you abandon the project .... not that i am steering you in that direction ..., i would be interested in purchasing the harness and controllers and intake manifold with all the related parts ..... provide an Email address and i can Email real wiring diagrams they will be white on a black back ground if you want |

Actually, in my case I was meaning "Naturally Aspirated". Sorry for the confusion. |
