Question about 1999 Chevrolet Silverado 1500

1 Answer

Slow start after warm up.

I have a similar problem. My 99 chevy silverado fires right up 1st thing in the morning. After driving for a while and then shutting off the engine and coming back to start it a while later, it will take 3 or 4 seconds of cranking to start up. Why would I have fuel pressure in the morning when it is cool, but not after warm up?

2007 Chevy Avalanche 3rd and 4th gear are not working


From what you are describing, it is possible either the 3-4 actuator is no longer playing with the 3rd & 4th clutch packs, only way to know for certain is to hook up the good ol' pressure gauge to trans. system, yeah, you think the Chevrolet dealer should know this right?

Sell it now if you can!

99 chevy silverado running rough and stalling.


the problem you are discribing would lead me to belive your fuel filter is clogged which is a simple fix 3 dollar part at any part store or on the worse hand your fuel pump itself could be weak you can open the gas tank cover and have another person turn the truck key to the on position without going far enough to start you will hear a faint whining noise if it is going bad or a louder noise if it is fine Good Luck

I have a 1999 Chevy Silverado 5.3, It won't start. I drove it home, parked it, and the following morning it wouldn't start. On a couple of occasions, i have had a difficult time starting it. On both of those occasion, I waited about 30 minutes, then cranked it and it started with no issues following. I have replaced all the spark plugs, spark plug wires, fuel filter, fuel pressure regualtor, crank postion sensor, I have cleaned all the injectors, checked the injectors with a noid light. I have checked the fuel pressure what matched the specs in the repair manuel, checked all the fueses, i have a fully charged battery, what should i try next, taking it to a dealer? I have not replaced the fuel pump, that was the last thing i wanted to replace. any suggestions?

Once truck is started if i drive it has a lag


I would have the computer scanned ( no SERVICE LIGHTS right ? ) looking for an errant coolant sensor not telling the computer to give your vehicle a bit RICHER ( a little bit more fuel ), since it does start. Just has POOR cold drive away. Hope this helps
