Question about 2001 Chevrolet Silverado 2500HD

1 Answer

Just began having starting trouble...

My 2001 Chevy Silverado 2500 HD just began having trouble starting. It will crank and crank and finally after 4 or 5 seconds, it starts. Have never had a problem with it since 2004 when I bought it. I'm thinking it might be a fuel problem but want to get a second opinion. When it sits for a few hours or over night is when it does this. If I'm driving it for awhile, shut it off and come back a few minutes later, it's fine. I pulled the Optima battery from my Jeep and tried it and it's doing the same thing so I'm pretty sure it's not the battery. Any suggestions....?

    I'll check all of that. It just started a few days ago and haven't had time to work on it. I hope it's not the timing chain. Thanks

I have a 2001 Chevy Silverado 2500 HD. The tow/haul light turns on (yellow) and will not turn off. Is this a problem?


It is if, it is locking out your overdrive. Check to see if it shifts into all the gears your transmission has... ie. 5 speed = 4 shifts.

My 2002 Chevrolet Silverado 2500 HD Diesel instrument panel went completely out and would not accelerate.


check your timing chain its probably broken. diesels have no spark plugs and uses compression ignition and uses a lot of battery charge to turn it over. thats why it sounded like it was dead. if the chain brakes the upper and lower cam and crank shafts aren't in time together so you get no compression ignition. sorry for your troubles and hope i helped

The O/2 senser will not make it qit but the fuel pump and the ingition module will. does it start right back up? Fuel pumps heat up and quit sometimes opened the relay and it cools and or is cycled as you try to restart and it reclosesand you drive on. an amp test on the pump draw or even a scope test of the pump may isolate it as the bad boy. Pumps build up pressure and heat if the fuel filter is partly clogged. Change the filter as preventale maintanance and try to blow though the old one if it blows though hard it may be too late for the pump and you may have to change it too as the stuff that went thohg the pump that stopped up the filter. You only can heat the pump so much before its bad if you find it is change the relay also and check the ground wire where it connectes to the frame. The hanger unit that the pump is in fails too and it has to be changed on most models as you can't buy the pump any other way because it fails as often as the pump or is damaged as the pump fails. The ingtion ciol can fail, but not likly to start right back up you gota wait. The ECM cando it too but is not a common problem. Their may be engine control codes in the computer to help you determine the problem

The reason is they are pressed in and you have to press them out with a tool and some have a C clip that has to be removed you can go to schucks or autozone to rent the tool to press out and it has to be pressed back in.
