general problems of the 2009 GMC Canyon

Intermittent and repeated partial failure of fuel system control module part number 20850907 during driving, including rough engine operation, loss of most of engine power on moderate highway grade, slowing to 15 mph under speed limit, and failure to restart approximately 15 minutes after shutdown. Malfunction indicator lamp lit and diagnostic code for low fuel rail pressure was recorded, but fscm malfunction diagnostic code was not recorded until after at least two incidents had taken place. Vehicle (VIN) entry into database returned "0 recalls", so NHTSA campaign 09v154000 remained unknown and ordinary replacement of fscm was attempted. When fscm 20850907 replacement was ordered, gm fscm part 20759945 was supplied, which failed to operate. Gm dealer refused to verify correct part number and withheld all information about NHTSA campaign 09v154000.

Attempt to start the engine after sitting for a few hours in driveway, the engine starts then sputters and stalls as if not getting enough gas and attempts to die. After a few moments, it finally catches up and runs. Engine has stalled while sitting at traffic lighs several times. According to document id # 2274089--- #08411 product safety- hard start, no start, engine stall- replace engine control module- ( may 7, 2009) I have taken my vehicle to a GMC dealership several times in the past along with a copy of recall but they claim that it is a service bullentin and not a recall so they would not fix the problem. I took my vehicle to an independent gateway service dealership and told them the problem I was having with the engine stall. They pulled up the recall and showed it to me and advised me to take my vehicle to a gm dealership for the recall that the gm dealership says that there is no recall. I have had this truck for 4 years now and the same problem exist but gm denys that a recall exist even when I have the paperwork in hand. The recall pertains to truck numbersbetween 98104805 - 98123129. My truck # is 98123053 which falls in that category. My vehicle falls into this category but has not been repaired since I have had posession. I would appreciate it if this problem can be resolved.

This incident has happened on several occasions. When taking off from a stopped position and going through the gears when accelerating quickly, the accelerator has stuck even when my foot is taken off of the pedal. This happens as I am shifting from first to second gear, when I take my foot off the gas then push in the clutch and shift gear and release the clutch, the computer does not respond to my foot coming off the throttle. The truck continues to accelerate even with my foot off of the throttle. The only way to stop the acceleration is to repeatedly tap the pedal until it releases. The first time this happened I thought that I might have inadvertently hit the cruise control but this is not the case. It seems that I need to allow approximately a one second delay from when I remove my foot from the throttle until I push in the clutch to avoid this situation. Is this typical of todays computer controlled vehicles?.
