Question about 1999 Chevrolet Silverado 1500

1 Answer

1999 Chevy Silverado 1500 hard to start

I had the fuel pump changed after my gas gauge was not working right and know it will start after about 3 min turning the engine over. Fuel filter has been changed and spark plugs. Checked all the fuses and relays and they checked out ok. I also removed the new pump and exchanged it for another one thinking it was defective but its still hard to start. I have about 140,000 miles on 4.8 L. engine. Any one out there can help thank you very much.

    When my check engine light came on I was told to change the gas cap. After changing the gas cap several times the light still did not go off. Now the gas cap is really hard to get off and the light is on. Please Help!

My 1999 Silverado fuel gauge jumps from 3/4 full to 1/4 full while on but in park. Also it has died a couple times lately while turning a corner. It will start right up if cold but if it is warm sometimes...

Sounds like your fuel pump is going out, I replaced mine at 120,000 miles. The fuel level sending unit is built on the fuel pump, so it will solve your level indication problem as well. The cheapest place I found a fuel pump was, believe it or not, on I searched for the part no., did a search, and found it there at the lowest price.

Changing the fuel pump is not really that hard - would take you and a couple of buddies about 2-3 hours. Email me if you need step by step instructions.

Hi I have a 1999 Chevy Silverado 1500 with the 5.3 motor in it. And Im having starting problems. In the mornings when the motors cold it starts just fine. Then when I drive it somewhere and park it then go...

It may have knocked some crud loose that could be blocking the line somewhat.
I would take the line loose in different sections and take some compressed air to the line and blow it out to make sure there is no junk in line.

To clarify my problem.... My 99 Chevy Silverado ran out of gas one day. As you know when this happens it sometimes toast the fuel pump... So i did have to replace the feul pump. It was a junkyard fuel pump...

It sounds like the fuel pressure check valve on the fuel pump has gone bad and your losing fuel pressure when engine is turned off. Try priming the fuel pressure twice, that's when you turn the ignition keys to the run position with out starting the engine for 10 seconds and then turning the key's to the off position and on again for 5 seconds. After the second prim the engine should start, to check this you can lone out a fuel pressure gauge and check the fuel pressure at the shredder valve. You should have 62 to 65 PSI during prim and once the engine is running, it should drop by 5 psi. As for your the accuracy on reading the right amount of fuel in your gas tank, the sensor is apart of the fuel pump sending unit and the float may have gotten bent and nothing you can do to fix it unless you take the fuel pump out again and replace the sending unit. Good luck and keep me posted.

2001 chevy silverado 4.8 gas gauge not working properly

Fairly common problem with GM vehicles. The sending unit in your tank has a small circuit board that an arm is attached to which moves up and down according to your fuel level. This circuit board and arm are not making good contact. Unfortunately the only good solution is to replace this part.
