Re: Buick PA 1991 no crank problem

Hi,

and thanks for the help again!

I did the test from the starter enable relay socket(THE RELAY OFF FOM THE SOCKET). The relay and its socket came down laying on the upper side of the driver side fuse box.


So, this is what are the results:


Pink/black coming from the ignition switch to the relay socket according to the wiring schema you sent,

-ign key off:no voltages

-ign key on: no voltages

-Ign key in crank: about 12 v


Black/yellow wire from the relay socket to the pass key control module,


- ign key off: no voltages

- ign key on: no voltages

- ign key in crank: no voltages




Yellow wire coming in to the socket,

- ign key off: no voltages

- ign key on: no voltages

- ign key in crank: about 12 v


The jumper wire connected between the yellow wires in the socket,

- the car is cranking and starting, but dies about within an one second or so.


So,


how you see, what is the problem and how to proceed?



BR, Pena
