Sounds like there maybe high resistance in the battery cables, a voltage drop test should be perform to ensure wires are good. You may try to jump start with the jumper cables attached directly to the engine block for the negative clamp and positive clamp attached o the alternator positive terminal or directly to the starter. if still no crank with that set up, try using a jumper wire from the starter battery terminal to the little wire attached to the starter which is the voltage signal from the ignition switch. if that still has no crank the starter is no good.

Could be the cables or the starter. Remove the starter and have it tested.

SOURCE: No Start when key is turned

Ma wish to check starter it could be bad or have loose wires on it. There may be a starter relay in the fuse box under the hood it may also be bad.

I assume the fuel pump fuse is good?
The only time voltage will be sent to the fuel pump will be the first 2 to 3 seconds if the starter is not engaged. You will want to crank the engine over and check for voltage on the load side of the relay, circuit #30 at the relay.
Let me know after you check.

SOURCE: 2000 chevy venture doesnt start

Not the IAC, or MAF, or 02

Does the Van Crank over?
Have you checked the IGN Relays? 1,2,and 3?
How did the Battery test out?
Anything below 11.9v battery is dead.
So I suggest that you do not throw any more parts and check the battery again.

My 2000 cavalier has done this for 6 months. You take your key out then open your door, wait ten minutes and the system resets itself and the car will start-annoying you bet!!!

SOURCE: i was having problems with

I have worked on quite a few chevys and can tell you what I've found to work with this type of problem. When you replaced the starter, did you tug on the fusable links that connect to the solenoid to see if one of them was burned and loosing power? There are two or three short pieces of fusable link attached to wires that power the fuse block and other electrical circuits at the solenoid / battery cable connection that will stretch when you pull on them if they are bad. If they are, then you won't have power for the fuel pump, relays and other circuits to make the truck start.
If one is bad, cut the wire behind the link connection and put a **** splice and piece of wire on it with a ring terminal,and connect it to the solenoid. Turn on the ignition and listen for the fuel pump to buzz. The fuel pump is controled by the ECM and makes the pump turn on for 3 seconds to prime the system with fuel before starting the engine. One of the wires on the solenoid with a fusable link does this. If this works, your done.
If the truck won't crank when you try to start it, check the "S" terminal for power with a test light while someone turns the key. The "S" terminal on the solenoid comes from the ignition switch, to the neutral/backup / clutch switch to the starter. You'll have to check every point in between these for power to locate the problem. One bad connection or part will keep the starter from getting power to the "S" terminal. You can use a screw driver to test if the starter is working by touching the two terminals together.
While your under the truck, look at all the wires in the harness for any chafing or rubing, I once found a wire that rubbed through and was causing the problem.
Hope this helps, Craig

Yes, even though the battery might have enough power to light the overhead bulb, it may not have enough power to turn the starter.
