#274 of 787 MAF / coolant temp sensor woes
Jan 22, 2009 (3:13 pm)
2002 Chevrolet Silverado 1500 4x4 Z71 5.3 Vortec
Engine. 109000 miles. Only on cold mornings/days
does it stall and idle really rough and missfire. Here is the strange part: if I unplug the MAF sensor, it runs
fine. If I plug it back in, goes right back to crap. So I
thought i had found my problem and replaced the MAF Sensor but to my surprise it did the same exact thing. It is throwing a coolant temp sensor code so maybe
that is the culprit. My question is if it is a bad coolant temp sensor, why does it run fine when I unhook the MAF? I also tried unplugging the coolant temp sensor but it still does the same thing if the MAF is plugged up.

There isn't a fuse for the chime. The airbag controller or body controller sends a message to the radio or amp module across the class 2 bus to perform the chime. You can't disable this message unless it is in the module's calibration. I don't think the dealership offers cals with the chime turned off.

On some models, one of the pins where you hook up the scan tool is fused with the cig lighter fuse under the hood. mine wouldnt work either and I found that the cig fuse was blown in the fuses in the electrical center under the hood. replaced it and scanner worked fine.

I have a 2004 Silverado that went through the same situation. Mine turned out to be the same fuse that controls the aux power outlet (cig. lighter). The fuse is located in the fuse box that is under the hood (drivers side). I can't recall if it was a 10A or what...but there are only so many to check. Test your aux power first (my guess is that it is not working), then after replacing the fuse you should test it again: if the aux power works with the new fuse, you should be all set. Good luck.

#281 of 787 87 - 94 tbi engine swap....
Feb 25, 2009 (1:56 pm)
I have a 87 tbi truck and I am installing a 94 tbi motor. Most items look as though they will swap out but the 94 seems to have two temp sensors and the 87 only one?
Do I use the 87 computer (1227747) or should I use the computer that came with the 94 (16146299) and just not hook up the temp sensor that is in the left side cylinder head as there is no provision for it on the 87 wiring harness. Thus only using the temp sensor in the inlet manifold?
#282 of 787 driver door not working no power
Feb 25, 2009 (9:51 pm)
did u check the relays for the driver door? when i recently put window tint on my truck i found 2 relays one for the driver side door and one for the passenger side so i pulled both of them so my tint wouldnt get messed up. relays should be under the hood in the fuse box driver side.
