I HAVE A 2003 CHVY SILVERADO WITH HE 5.3 V8. THE

I HAVE A 2003 CHVY SILVERADO WITH HE 5.3 V8. THE FUEL PUMP WAS REPLACED LAST YEAR APPROX 30,000 MILES AGO. THE ENGINE IS SLOWTO START LIKE IT IS NOT GETTING FUEL. SOMETIMES IT TAKES 2-3 TIMES CRANKING IT FOR IT TO START. IT SOMETIMES WILL START AND BE REAL SLUGGISH FOR 2-3 SECONDS BEFORE IDLEING UP TO NORMAL. THE YELLOW ENGINE LIGHT IS ON, AND HAS BEEN DUE TO AN EVAPORATION CANISTER BEING DIRTY AND THE SOLENOID NOT CLOSING - HENCE NO VACUUM. wOULD THIS CAUSE THE SLOW START, OR IS THE FUEL PUMP GOING OUT AGAIN?

If there is little or no vacuum going to the engine at time of start up that will cause the engine to be hard starting, what it does is since theres not much vacuum if dumps crazy amounts of fuel into the cylinders to aid in starting, also would cause it to run funky for a few seconds after its started

May need to replace the fuel pump on my 2003 Chevrolet Silverado 1500 V8 Vortec. Is the pump inside the fuel tank?


Yes. As per federal law all electric fuel pumps must be inside the fuel tank in case they fail. This prevents fuel from spilling on the road.

I have a 2007 Silverado WT (new bodystyle) 4.8 V8 and has 30,000 miles on it. Check engine light came on and it was PO171 and PO174 (system to lean Bank 1 and 2). The problems are trys to die when I start...


If you are having a lean indication,and miss-fire,then the fuel pressure is most likely the problem,change the fuel filter,if this does not help,then have the fuel pressure checked,the fuel pump maybe weak,if this was at all helpful,please rate,thank you.

My 2003 Silverado will crank,but not start.changed the fuel filter,but no help. how do i check to see if the crankshaft sensor has gone bad? and,in cubic inches..what does a 4.8L V8 come out to?


Easiest way to check is with a scan tool.In data stream it should show rpms while cranking if it does not then the sensor isn't working.Is the fuel pump coming on? Usually you can clearly hear a buzzing noise from underneath the vehicle while cranking. Roughly 293 cubic inches is a 4.8L

When should you change the fuel pump on a 2003 chevy silverado


You do not have to change a fuel pump as a matter of maintenance. A new one could last a year and fail and the old one might never. If you are hearing a lot of noise and it is taking it longer to start, you might be getting indications of a pump that is failing. Have a pressure test done and see if it is taking too long to come up to pressure.

Most people only know it is time to change the pump when you have it towed in with no start.

I knew I had a problem with my 99 Tahoe for weeks and still I had to tow it from church. Oh well I knew it was going.

hope it helps.

'92 Chevy pu V8 will not start spray in starting fluid and it starts then starts rest of day. sits over night have to go back to spraying with starting fluid. What is the problem? How do I fix it? '92...


With your Clarifications I suggest having the Fuel Pump Pressure Tested as one other gentleman suggested that it is most likely bleeding down overnight. Another possibility would be the Fuel Filter being clogged. The factory recommendation is to change fuel filters every 30,000 miles. Many people do not even know a Fuel Filter exists on their vehicles. Some years back they were near or in the carb. Weak Ignition would be the last thing to look into as the vehicle runs somewhat normally once started and running for a while. Modern vehicles have Electric Fuel Pumps inside the Fuel Tank. This is somewhat expensive to replace but necessary maintenance after many many miles. Good Luck!

Trying to find the fuel pump FUSE.


There is no fuse specifically dedicated to the fuel pump on this year and model of Suburban. This Suburban is equipped with dual tanks and as such has two relay switches, primary and secondary, both of which are located at the main fuse box in the engine bay, that power up the respective fuel pumps.

The closest fuse (15A) controlling either of these relays also powers up the main control module (located beside and below the main fuse box). So, if one needs to disconnect the fuel pumps from functioning, then the only effective method is to disconnect the fuel pump relays.
