Question about 2001 Chevrolet Silverado 1500

1 Answer

I have a 2001 chevy silverado 4.8L and I have replaced fuel pump, fuel filter, and fuel pump relay but still having the same problem. The problem is that my truck starts up fine when cold or starting back up right after it is shut off, but if I try to start it back up after waiting about 15 minutes on, I have to floor it and it takes about 3 or 4 seconds of turning the motor over and when does start a big cloud of white smoke billows out of exhaust. It also has unsteady idle when in drive. the shops cant figure it out and they said they even checked the oil pressure sensor.

SOURCE: black smoke from exhaust

This is almost certainly a split hose - mine was the large hose coming out of the bottom of the EGR valve.

Speaking to a parts guy at my local Jaguar dealer, he said that the new part is uprated as Jaguar are aware that this is a problem.

The split allows more air in and results in the ECU changing the mixture and over fuelling - Black smoke is an indication of un-burnt Diesel. As well as the black smoke you may also notice a whistle/whine or sucking noise when you accelerate and a lack of power / lumpiness at around 2000rpm.

Hope that helps!

SOURCE: hard start

Its your fuel pump.I had the same plomblem not too long ago.I was spraying either in to start it.I have a 97 chevy truck witch requires 65 psi to start and 55 to run properly.You need to find out much psi you need to start it.You can probaly look in your manual or just make a few calls.My truck had 55 psi and it ran fine i just had to get it running first.Good luck.I wonder if that fuel pressure regulator was a waste of time like it was for me.

SOURCE: chevy 4.3 fuel prombems..?

I'd be replacing oil sender. GM have used oil pressure switch as a safety shut-off to fuel pump, when oil pressure drops off, as it would in a collision, due to engine stall.

SOURCE: 1994 Suzuki Vitara V6 H20A Engine smoking intermittently from exhaust

I have a Mazda which in Australia (here) is called a 323 Astina, overseas a 323f, Familia, etc.
It uses a 2.0L Mazda KF Engine very similar to (in fact co-developed with) the Suzuki H20A engine, except designed to be transverse, variable resonance induction and other different tuning inc. 7000 redline, and probably not as reliable as an H20A.
I've had the engine rebuilt because I want to keep this car for a while and it needed it. Oil slipped past the rings which burned out grooves on one of the exhaust valves on Cyl-6 to the point where that cylinder had no compression...
... but I still get smoke occasionally, as you describe yours except not as often nor on the open road at speed. It happened ever since the first time I changed the oil after the rebuild. The tech who rebuilt it used a grade of oil I couldn't find and, liking synthetics, I used a lighter oil.
About the time you were writing your message, I replaced the rubber intake pipe feeding the throttle body and I noticed the inside of the intake manifold lined liberally with oil. The old pipe had oil only at one end.
The pipe I replaced didn't just go from the air mass sensor on the filter box to the throttle body. There was also a large pipe to an air reservoir (a lengthy pipe sealed at one end so that if you open the throttle quickly, you don't have to wait for more air to be filtered before it enters the engine, supposedly) and a tiny pipe to PCV valve.
It's not a long pipe so it's easy to look inside. The reason I'm boring you with all of that detail is because you'll almost certainly have a different one, but this is still most probably something you'll find feeding your intake manifold a supply of oil. The PCV (Positive Crankcase Ventilation) valve runs from one of the rocker covers (not that we have rockers) into a pipe feeding into this intake pipe. It's supposed to **** air in from the intake pipe due to a vacuum created by another pipe connecting from another part of the crankcase to the intake manifold (after the throttle body so it has a lower pressure than the intake pipe) and that might be happening in my engine but oil is, or was before the rebuild, seeping back into the intake pipe.
Being a transverse version of your engine, the PCV valve is on the front bank and the pipe from it to the intake pipe is quite short. The PCV valve is also situated above (if I remember correctly) a cam lobe so at higher revs, the oil gets flicked up into the PCV valve.
... so use an oil which is thicker at high temperature, do a compression test, or as I'm considering, run the pipe from the PCV valve into a canister to catch the oil before feeding the gasses into the intake manifold. That way less of the thinner oil will be burned off and I'll have a better chance at getting away with using it.
I use 15W40 Oil - viscosity of 15 weight (units?) when hot, 40 in Winter (which the W stands for). I should use 20Wxx, perhaps, to burn less oil.
This engine likes thin oil, it just goes on to liking it enough to inhale it. This engine also likes higher revs.
Hope that helps.

I have a 2001 chevy silverado 1500 with a 4800 vortec engine. it starts and idels fine but when ever i give it gas, the engine starts to sputter and dies. ive already changed the fuel filter and spark plug...


This sounds llike weak feul pressure, the fuelpump may need replacing, the first thing to do is have the fuel pressure tested and if the pressure is low then have the pump replaced. the pump is located inside the fuel tank and the tank will need to be dropped to replace the pump, good luck ,

2001 silverado v6 died while pulling into parking lot. Cranks but won't start. Can't hear the fuel pump engage when I turn on the key. Replaced fuel pump relay. Does this mean I have a bad fuel pump?


Try spraying an alternative fuel such as induction cleaner into the throttle body and see if it runs.If it does most likely cause is the fuel pump.

Just replaced the fuel pump in my 2003 Chevy Silverado 1500 4 wheel drive. It now starts, but won't stay running when idling. Any ideas?


also u may want to check the regualtor take to a mechanic and have him put i pressure guage and to make sure pump is pumping right amouth of psi. you could have broke some of the plastic on pump when putting in. If good psi then maybe relay or regulator under intake.

Is their a fuse for the fuel pump ( not the fuel


it appears that fuse 30 and the relay right beside it are for the fuel pump. the relay is definately for the fuel pump tho. it's located in the fuse panel inside the engine compartment near the battery.

FUEL PUMP FOR CHEVY SILVERADO


fuel filter? how about power to the fuel pump,loose ground wire to chasis? wiring harness? terminals clean at point of connection?did you check the fuel pump relay? Relay is located in electrical center under the hood on the driver side.relay and fuse legend will be on bottom side of cover, you sould be able to switch with another relay that you know works, ie: switch horn relay with fuel pump relay, honk horn to insure both relays are working when either relay is inserted into horn slot. Do you by chance have the electrical schematic drawing for the fuel pump?
