SOURCE: 99 pontiac grand prix 3.8 l.No battery power to pcm

Pin 20 on the blue pcm connector is the power wire to the pcm it is an orange wire. (hot at all times). The power to the data link connection is the cig fuse in the i/p fuse box.

What is the exact problem you are having?

SOURCE: code P0442 on a 2000 grand prix

That means that there is a fuel evaporation leak detected in your fuel tank. Generally this means that your fuel cap is loose- go tighten it and see if the code goes away after driving your vehicle for awhile. The problem can also be holes in the evaporation hoses...but not likely.

My 2000 Grand Prix GT is losing cylinder fire exactly at 60 mph while accelerating every time. Then the Trac warning light flashes once. It runs fine below 60. Noticed no Speed Cont. fuel pump relay.


What engine ? could have 3.1 or 3.8 L No resistor ? for what ?
Noticed no Speed Cont. fuel pump relay. What are you talking about . Are you talking about no control for the fuel pump relay from the PCM/ECM engine computer ? The PCM Energizes the fuel pump relay for two seconds when key is first turned on . Two second prime of fuel system . When cranking the engine the PCM/ECM will only energize the fuel pump relay if it see's an input from the crank sensor .

42/44RE auto trans, TCM?

read chapter 21. it covers the whole deal.
there is no PCM
like most cars , this era, they moved the TCM in to the confines
of the ECU , and renaming it PCM on that idea.
read page 21-6 carefully.

00 grand prix w/ 3.1 vent valve staying open white wire has no voltage and is not regestering as a ground. pink wire is putting out voltage constantly even when genisys switches valve closed (supposedly)...


This particular valve is supplied power all the time. The pcm toggles the ground to turn it on and off. While commanding it on and off try running your test lamp between both terminals to see if the circuit is working properly. If it is replace the vent valve.
