I went out and started the car and let it warm up to op temp and turned it off. Came out 20 mins later turned the key and the engine cranked over but would not start,it's been a long time since something like this happened. My first thought was maybe a fuse had blown,but after checking them they were all good.
My next step was to go to the site Steve Wood has Vortexbuicks-etc.com
I went to the first page of troubleshooting and did the injector noid light test and the noid light blinked when cranking the engine over, so i had injector pulse from the ecm and the cam and crank sensors were working.
I then did a spark test and there was no spark. I followed the troubleshooting tree for no spark and after testing for voltage at terminal P on the module connector it showed no voltage there,it should have showed battery voltage. I had installed a hotwire to the ignition coil earlier this year and the relay went bad not sending power to the terminal P wire for the coil. So after reconnecting the wires to terminal P and bypassing the hotwire and relay i checked for power to terminal P and it showed battery voltage and the engine started right up when i turned the key. I really hate when my car doesn't run. It's all good now though.
The relay was a heavy duty type from autozone but it was probably made in China. I guess i need to see if i can find one made in the USA if that is possible.
I'm pretty sure i would have found the source of the no start condition as being the hotwire i had installed but it's nice to have a site like that of vortexbuicks-etc.com to have handy in case that it's something more complicated.I thank Steve Wood for having made a great site to help us all in keeping our cars running and road worthy so we can enjoy driving them.
