Problem for Chevrolet 1999 Silverado 1500
Service Engine Soon Light comes on but doesn not stay on.
By wsimpson333 on Dec 21, 2008
On a cold morning I go to start my 1998 Silverado Pickup truck. It starts but will not stay running. It does this several times, but then appears to be OK except the Service Engine Soon Light is on. The light stays on all day. The next time I start it, it starts right up, but thelight is still on. The next day I go to start the truck and it starts right up and no Service Engine Soon light. Everything is fine for about a week then the same thing happens over again. Does anyone have an idea of what is causing the problem? It seems to happen only on cold mornings. The truck runs good even with the light on. I have a 60 month battery that is over due for replacement, could this be contributing to the problem?

- on really cold mornings 20 or lower my silverado will start right off, run the tach to about 2000 rpm and come down to 800 or 900 rpm right before coughing and hacking it's way to a stop. My engine light is also on, took it to my mechanic, says not to worry about it. I changed the fuel pump about 300 miles ago and havn't seemed to have much of a problem since. But it also hasn't been as cold. - caseylhallJan 26, 2009
- My problem is similar but mine seems to start better the the colder it is. THe security light was coming on when driving but appears to be gone know. I just changed my plugs and wires, fuel filter and pump and my alternater. Battery light stays on so I changed it as well. The voltage gauge goes crazy except when I slow down in a neighborhood. I almost think that it is the ECM? not sure can anyone help? - kmcdowell80Best Solution

If your battery starts turns the engine over, it is doing it's job well. It sounds like your engine computer is not liking the cold engine. If it has been a while since a tune up, it would not hurt to go ahead and do it, but if it runs ok after it warms up, I sould not worry about it a whole lot. When the engine is cold, the egr valve and other things that are made to limit polution tend to stick and give the computer bad readings. A serious tune up may fix it, and I think should, but you MAY still be in the same boat! That does not FIX it for you, but should ease your mind on the light.
