Won't start after long distance drive got spark let set for about a hour then it started don't know how to fix it can you help it dose have a new fuel pump in it

It won't start. It turns over and acts like it's going to start but don't. I thought it was a problem with the security system but I've done all the bypass tricks that normally work but it won't work. I've changed all the spark plugs and fuses and the battery. Also changed the fuel pump. I've checked all fluids plus the fuel pump and starter and both kick on just fine. The security light stays on flashing and the battery dies extremely fast. Anyone know what the issue could be and what I can do to fix it? My truck is the newer body.

Stalls out while driving at low rpm , changed alternator, battery and 2brand new fuel pumps and still stalls , getting worse, before temp gets up it seems to run A ok ???? Please help !!

Running rough. Feels like fuel filter. Or pump. Are both in my gas tank? Or could this be a sensor?

Vehicle shuts down without warning. Fuel filter housing must be reprimed to enable startup. Issue is sporadic but generally happens at the worst possible time. OEM filter housing no longer available so I am considering a rebuild kit which is basically new seals. TIA for input.

Fuel pump is not working looking for a fuse. I can’t seem to find one.

I have a 2008 silverado some fuses in the fuse box is not getting power like the fuel pump and starter not kicking in and the injectors is not turning on please help

So we turned truck off to go in a store came back out turned key over and nothing happened. No click like the starter was even trying to do anything. Everything inside truck worked except the heater or air would not come. On...which was really and you can here fuel pump kick on when. Key turned on weird. Battery fully charged we have never a ever had one problem with this truck. We have che ked fuses. Relays u name unless we are missing something only vehicle we have please help.

Let me start by saying I replaced mass air flow sensor and fuel pump so far but the issue still occurs when I start the truck in the mornings it acts like it's not getting enough fuel but once it's started it idles and runs just fine if I start it soon after it starts fine as well only does that after a few hours of sitting. Anything you all recommend to check other than fuel injectors as those are gonna be tested today?

Truck was running fine. Changed out the 4L60E transmission with a newer one. Put everything back together and now the engine won’t start. It’s turning over but not starting. I don’t think it’s getting power to the fuel pump. Have changed the fuel pump relay. Any suggestions would be greatly appreciated

My father has a 2009 silverado with the 5.3 ls. He rebuilt the engine due to a lifter roller being completely flat. Got it all back together and it ran. With in a week it got to where it would run shorter periods of time to like now, it will crank but very briefly start and shut off.
If you spray starting fluid in the intake it will stay running until you stop. The fuel pump is brand new.

New fuel pump... sparkplug wires... when I go it barley takes off... would a bad distributor cap cause that?

On the diagram it’s calling for relay number 43 but in my fuse panel there is not one that exists. It’s just empty in that location.

When trying to crank engine motor does nothing. No power to coils, fuel pump or starter. Can get the motor to spin by jumping starter relay pins #30 and #87. Accessories work.

Engine died en route. Battery fine but sounds like fuel starved.

I was averaging 22.5 mpg with the stock tires. I bought the same tire and now my gas mileage is approx 19 mpg. I put in a new airfilter and it did not help. The tire pressure is 37 psi.

Ok I went to start my truck today and then a few seconds later it died. I tried this few more times with the same result. Charged it and still did the same thing. It was acting like it wasn't getting any gas. I've been told it could be the fuel pump or several other things what could it be any and all help would be really helpful.

I replaced fuel pump relay ,fuel pump,fuel filter put a new battery in it the first time i tried to start it it made a spinning noise like sumthing wasnt cat hing i tried again this timeit tured over but wount start and the battery died i tried to boost it turned the key nothing tryed to charge it n the same thing wont turn over all the accsessery work dont kno were togo crom here dont want to keep tbrowing money at it

The light comes on at 75 mpd, code P0300, changed wires, air filter, added fuel injector cleaner(twice), runs fine, no change in performance. What else should I do? or not worry about it?
