#353 of 364 2001 Sonoma Will Not Start by sarahlee87 Aug 24, 2009 (6:23 pm)
Hello. I have a 2001 Sonoma that will not start. It seems to have problems when its damp outside or if i dont drive it for the weekend. Come monday it will not start. So today..monday.. i go to start it and all it does is turn over and thats it...or it tries to start backwards...ive got it to start every time it has done this but this is the worst its ever been. Ive tried jumping it... it has a brand new battery, not even a month old! my dad recently put new plugs and wires in it also. this truck hasnt even seen 98,000 miles yet! its also has a new cat that probably a little over a year old now.. no one can really seem to figure out whats wrong! HELP! thanks for your time... P.S. its a V6 automatic if that helps at all.

1996 GMC Sonoma 4.3 V6 5sp manual trans. At 3/4 to WOT throttle the vehicle surges/bucks and is not making the power it should. No codes, runs fine other wise. Also yesterday while stuck in traffic it appeard to become stuck on high idle at 1900rpm, pushing the vehicle along and idleing at 1900 at stop lights. After sitting 2 hours was back to normal. Again no codes.

Replying to: plexico48 (Oct 05, 2009 6:17 am) If you google around I think you will find a unit a lot cheaper then the factory one, it will let you run just gasoline.
#361 of 364 96 GM Sonoma Code p0300 by wmwink Oct 14, 2009 (5:31 pm)
Can a bad MAF sensor give me the P0300 Code? The Service engine light comes on and stays on for a few days then goes off for a few days. The truck memory shows the misfire code. When light is on I get a MAF code as well. Where is this part located at on the truck? Thanks for any input as I am wanting to sell this truck but want it fixed first
