91 transam cold starting

91 transam 5.0 tpi doesn't want to start without pressing the gas pedal. When it does start, it runs rough for a couple of minutes and finally runs good after a little "warming up ".

Re: 91 transam cold starting

Check the temp sensor. My -88 was acting like that when the ECU was broken and the 5V-circuit that feeds the temp sensor only put out about 2 Volts.

When I finally got a ALDL-cable and plugged it in, I could see in Live Data that the temp sensor reported +30 degrees C to the ECU when the engine was actually +6 degrees C.
