Truck will not shift fro 2nd gear to 3rd gear.

The truck has set for 7 years. I have changed: plugs and plug wires, rotar and distributor cap, sensor on throttle body, and of course all of my fluids.

I replaced master cylinder. still no pressure. tried to bleed brakes with no fluid coming out. I am at a loss of what to try now

Just started missing all at once

Was told starter was bad and needed replaced even when it starts it starts the truck. Could this be the problem?

I have a 1990 Chevy Cheyenne 1500 heavy half ton with a 3.4l v6 and a granny 4 speed transmission. I want to drop a 70's 350 in it. The transmission and everything else bolts up except I need different motor mounts. Is there a conversion motor mount I can buy or is this something that needs to be fabricated

It shifts into 1 and 2 but won't go in 3 just free balls and it just started change filter fluid and still won't shift

Sorry for the novel, I'm just pulling hair out now (and I'm bald!)

Truck starts right up, but only at a super low idle for about 4-5 secs, then kicks up to a normal idle. Drives perfect with quicker response than before – but only if slow acceleration (bogs if laying on pedal) - until braking or slowing down, then stalls out and dies completely. O2 sensor not swapped out yet because passenger side manifold needs replaced and y-pipe disconnected from manifold on that side. Vacuum lines are either good or new.
EGR was so clogged, it was SOLID in the tube and PCV flow through tube on the driver’s side had to be dug out and then cleaned. I know, I know…
NOW, after replacing and cleaning all of those items, there’s a NEW issue – an exhaust smell in the cab!

It runs great when fixed properly and ran steady (even with what needed to be replaced) up to this point.

What’s even left after this point?
The PCM? Maybe a bad ground or connector somewhere? The O2 sensor?

Running rich problem is fixed; no fuel smell in exhaust; injector spray pattern looks right, but won’t hold steady; truck started to choke and “suck” air and fuel for a couple of days –fixed. The truck used to “whistle” while “sucking fuel from the TBI – fixed. What will make keep making it stalling and dying out now? Other than the O2, I'm at a loss

Truck cranks but doesn't start it will run long as you pour fuel in intake has right fuel pressure and it's getting fire I'm lost maybe anti lock system (bypass) i seapped a 98 1500 to a 95 1500 vortec all wires or hooked up and changed harness don't understand please help

my 1996 Chevrolet C1500 will not start without the use of starting fluid every time the engine has been turned off for an hour or more.

change dishberter and cap

I have replaced the timing chain also a complete distributor,cap rotor,plugs and wires I have to advance the timing all the way to the firewall to get it to start I have spent $600 just on parts I am really confused and no one can give me an answer I have never had this much problem with getting a vehicle running. I am just about ready to put a 350 engine from my 76 Monte Carlo because I don't want to have to replace the cam . The timing is on top dead center the rotor is pointing to the #1 tower

drop and drain a gas tank

Speedometer is not working now. Transfer case is 246 gm. Engine is a 5.3. Had code for vss,502 I believe, replaced sensor and cleared code. Need help thanks.

The truck is a 6 cylinder and runs great otherwise. Already changed battery, MAP sensor, rotor, distributor cap, sparkplugs and wires, knock sensor, fuel filter and checked fuel quality and all fuses.

I changed the oil pan gasket and the low oil level lights comes on and the antifreeze looks brown now.

The problem only occurred once, I was going over train tracks, and it was out of the blue, the truck just lost almost all power, and then it got going again

I have taillights and brake lights and dome lights.. only 1 low beam works and both high beams work..

I put a new timing chain and gears in it turns real fast fires every once and a while the fire is yellow

it just got a tune up. It did it before and after tune up. temp is normal. It seems that when I let it sit for awhile. It goes back to normal until 40 miles again.

I'm about to purchase from a private party and want to know if it's worth it for how much I'll have to put in.

How do you install pvc

Neutral or electrical box

Center of my truck is the 4wd lever, what is the cover called?

fairly mechanically inclined. live in Alaska, yes its cold! so i drove to work, and when i got off work my truck would crank but not start, my buddy told me it was not getting fuel and i needed to change the pump. i changed the fuel pump relay and she fired right up! the next day it did the same thing crank but no start, this time i unplugged the fuel pump relay for half hour or so plugged it in and she started! went home and changed the fuel pump anyway. the next day the same thing, crank but no start! now its -30º F here so i had it towed for $100 bucks to my house, rolled it into garage and for shits and giggles i turned the key and she fired right up! my kind of luck. whats going on? recent history before this started, just replaced the water pump, thermostat, thermostat sensors. no codes being thrown...
