#21 of 193 1995 CK2500 Will not Start by ubware Aug 20, 2007 (1:41 pm)
1995 3/4 ton truck with 454 was sputtering, changed fuel filter, ran little better. Next day it sputtered at stop light, limped home and next day started it and it died and will not start now. Checked fuses(OK), checked fuel filter(OK), no spark. Help! Charles Replies to this message: diehard40 (Aug 21, 2007 4:51 am)

Replying to: ubware (Aug 20, 2007 1:41 pm) how about the fuel pump, however they often (or at least in my experience) don't give any warning prior to going out.   For those that have replied to my 88 problem. I finally got it solved. After changing the fuel pump initially and not solving the problem, i thought it may just be a bad pump and was gonna change it again. that is when i noticed that somehow the ground wire was broken that goes to the fuel pump. repaired it and it fired right up. Often the little things that get overlooked or missed.

Replying to: diehard40 (Aug 21, 2007 4:51 am) I have had this truck for three weeks. Yesterday I was at the beach fishing and on the way back it would not start. Initially it started, and withing 5 feet it bogged down and would not start after that. The battery is fine, the starter seems to be fine (it keeps cranking but the engine does not start). I got it towed to the dealer and will be finding out more soon. I hope this is not the beginning of a chronic problem. But in case it is, I was hoping you could give me some information on how to recover the cost / or how to approach using the lemon laws to get this thing replaced?
#25 of 193 2003 Silverado V6 will not start by sjors1 Sep 28, 2007 (12:59 am)
Hi,   My brother bought a 2003 Silverado from an American insurance company. It has a couple of dents and scratches but we can fix that. Unfortunately the car arrived in Holland without a catalysator, so my brother bought one from a scrapjard. The only problem is this catalysator is for a 2003 v8, it fits perfectly. But the connectors from the lambda sensors are different. We managed to connect them, but the engine won't start. It turns over for around 3 seconds and then stops.   My questions are: Is it possible to use a v8 catalysor on a v6? Do we have to change the 4 lambda sensors? Is there an other reason why the engine wont start?   I would really appreciate it if someone could help us out! Replies to this message: sjors1 (Oct 01, 2007 10:44 am)

Replying to: rusty25 (Jul 04, 2007 6:34 pm) I have a 2003 Silverado, and in the last year and a half or so it has decided that it randomly won't start. When I turn the key all the lights and gauges, radio etc comes on, but the truck won't start. It does not make any clicking or anything, I have been to the mechanic more times than I care to think about and no one can figure out what is wrong. It happened today twice in less than one hour, and it has never done it more than once in a day, so I went to the mechanic, and of course it started. The starter has been checked, its fine, new battery, cables are tight, relays have been changed, and it keeps happening. I feel like I am loosing my mind over this, and since I never know when its going to happen, it worries me because it may be 5 minutes to an hour or more before it decides to start, and I dont need to be stranded for that long by myself. If anyone has any ideas, please let me know, because I can't just keep dropping it off with mechanics for days at a time and never finding anything out!!

Replying to: srouby2403 (Nov 02, 2007 2:27 pm) Had an Ods Aler (GM product) same thin.. replaced the igniton and was told by the dealer if the key is a bit off . the car will think it is a theft and shuts down the fuel system? Never happened again after the relacement? good luck?
#30 of 193 Starting issue by silchevy00 Nov 14, 2007 (2:19 pm)
I have a 2000 silverado and it has a starting problem. It takes me about 3-4 times to start it. It turns over everytime, but wont start until the third or fourth time. It sounds normal when i try and start it, it just wont start. When it does start it takes a second for it to completely start up, like its struggling for fuel. Ive already replaced the battery and fuel filter. It seems like a fuel delivery problem to me, or maybe a sensor is going bad. I have no way to tell that because no check engine light has come on. Any ideas?
