#125 of 193 GMC won't start by 02gmfan Mar 28, 2009 (6:18 pm)
I have a 2002 GMC Sierra. About once a month the truck will not start. All the dash lights will come on and the radio will work when I turn the key. Its like I am starting the truck in gear. After about 10 min I hear a click and the truck will start and I am not getting any codes from the computer. Also I keep topping up the coolent. I had a presure test done for 15 minutes and the gauge didn't move. Any ideas   Thanks Replies to this message: rossterman (Mar 28, 2009 7:34 pm) 02gmfan (Mar 29, 2009 7:35 am) rossterman (Mar 29, 2009 9:52 am) and 2 more...

Replying to: 02gmfan (Mar 28, 2009 6:18 pm) Hey 02gmfan. My 2001 sierra does the same thing. Occasionally won't crank but all of the lights and guages are working. I was told to check for voltage on the short stud on the solenoid with key in the crank position. Tried it and don't have voltage. I replaced the start relay under the hood in the fusebox; still didn't work. Something is stopping voltage from being sent to the starter but I can't figure it out. If someone gives me a fix, I'll let you know. By the way. How do you look at replies to these questions?

Replying to: rossterman (Mar 28, 2009 7:34 pm) Thanks rossterman. I'll let you know if I get a fix as well. I don't understand the question you're asking me about repling to questions.   thanks Replies to this message: rossterman (Mar 29, 2009 9:52 am) 02gmfan (Mar 29, 2009 2:35 pm) 02gmfan (Mar 31, 2009 5:48 pm)

Replying to: 02gmfan (Mar 29, 2009 7:35 am) My bad, I figured it out. Back to the starting problems. I'm wondering if it has to do with the ground cable on the battery. Yesterday when it wouldn't start, I popped the hood to see if the start relay was clicking and I moved the ground cable out of my way. Immediately after that it started. Coincidence? If it's the cable it has to be internal because there is no corrosion visible. Replies to this message: 02gmfan (Mar 29, 2009 2:35 pm) 02gmfan (Mar 31, 2009 5:48 pm)

Replying to: rossterman (Mar 29, 2009 9:52 am) Thats a good start. I would explain no power to the starter. The next time it happens I will move the cable around. Until then I think it is time for a good battery post and cable cleaning.   I'll let you know   thanks

Replying to: rossterman (Mar 29, 2009 9:52 am) Hey rossterman I screwed with the negative cable as well and she fired up. I am going to clean the ground conections to the starter. There is another ground to the front of the truck, that could be why the dash lights and radio will work but the truck will not start.   Thanks
#132 of 193 2001 gmc Sierra does not start by ck1500 May 01, 2009 (10:03 pm)
My son was driving the truck and all of the sudden it turned off on him. He tried to start the engine and it would only turn but not start. I had changed the fuel filter and it still did not start. It currently has 80k miles on it. What could be the next problem? I was thinking it could be the fuel pump, but it has a full tank. When I removed the line off the filter, it has gas in the line.

I tried to start it again and all it does is turn over. It seems as if the plugs are not getting a spark. Would and OBD reader give me the answers I need to determine the problem? Replies to this message: obyone (May 01, 2009 11:12 pm)

Replying to: ck1500 (May 01, 2009 10:05 pm) Sounds like a bad throttle position sensor.
