91 929 no start onley when the hold light is flashing car has 179000 on her aney help where is the traney ecm located ??

 

By no start do you mean it does not crank over or that it cranks over fine but engine will not start up and run? Possible transmission range sensor/inhibitor switch fault allthough there is not a transmission code for it. The trans control module is underneath a metal plate under the passenger floorboard carpet right next to the engine computer.

 

Does it start in any other gear range?

 

babyhuey sorry i dint get back to you sooner I drive truck im out a week at a time .yes car cranks ,wont start in aney gear the hiold light dose go out turn key off /on ect when hold light stops flashing she starts right up
i re placed nutral safty stwitch with new one 3 months back no start /cranck shift indacator stoped working ,i replaced the n/safty stwitch shift indacator now workes the hold light is intermint wanted to make surs the traney/ecm was grounded ,will check it now i know ware it is ,thanks

 

If she cranks over ok then would not be overly concerned about the TCM or Inhibitor switch. Those kind of faults would not even allow the engine to be cranked over. Curious why the hold light flashes when it will not start though and then when it does not the engine will start up fine?????
