#87 of 193 Hard Cold start. by civicpilot Oct 13, 2008 (1:38 pm)
Hello All, I have a '96 GMC Sierra. 5.7 liter. For the past month or two has been a little hard to start when the truck has been sitting for 5 or more hours. however the second it starts I can shut it right down and have no problem restarting. after leaving it for 5 days became impossible to start when cold without starting fluid. again the moment it starts I can shut it off and restart it immediatly with no hesitation. I replaced all plugs and wires, Battery, Fuel filter, to no avail. changed fuel pump yesterday and now it wont start at all. Pump is running and fuel is getting to the pressure check valve on the fuel rail.   PLEASE HELP! Thanks Dave Replies to this message: obyone (Oct 13, 2008 10:07 pm) civicpilot (Oct 13, 2008 11:22 pm) obyone (Oct 17, 2008 7:51 pm)

Replying to: civicpilot (Oct 13, 2008 1:38 pm) Yes but sounds like the check valve has failed since it doesn't hold the pressure after 5 hours and thus the hard starting. Replies to this message: civicpilot (Oct 13, 2008 11:22 pm) obyone (Oct 17, 2008 7:51 pm)

Replying to: obyone (Oct 13, 2008 10:07 pm) you know I thought check valve, however, it didn't help at all when I leave the key on to run the fuel pump for a few moments. And since replacing the fuel pump I can't start it at all. Replies to this message: obyone (Oct 17, 2008 7:51 pm)

Replying to: civicpilot (Oct 13, 2008 11:22 pm) There are only two things to check when there is a no start condition. That is spark and fuel. One of the two is lacking now to figure which.
#92 of 193 96 Silverado will not start by chrisgh Oct 19, 2008 (4:20 pm)
I own a 96 Silverado with a 305 engine 130,xxx miles. It has been running great until last week. I got in one morning and it would not start. I automatically thought it was the battery. but then I notice my lights and radio and all were working fine, plus when i would turn the key i could hear it hitting the starter. I went ahead and had the battery tested and it is fine. The truck will not start on its own but if I use another car to jump it, it still will not start. Im not sure what to check next? If anyone has any ideas that could help please let me know. Replies to this message: 2001hd (Oct 19, 2008 7:38 pm) obyone (Oct 19, 2008 8:41 pm)

Replying to: chrisgh (Oct 19, 2008 4:20 pm) Try banging on the starter with a ball peen hammer and see if it will start.
