Engine is a no crank over?

Hello,

The security light is the issue, the engine will wont crank over with the security engaged. When you did the ten minute relearn did the security light stop flashing and did you start it within five seconds?

It sounds like the battery is weak or the starter has gone out but to be sure lets check out these guides, they can help us fix it

Please run down these guides and report back.

Never stopped flashing.

That is the issue then. I would remove the negative battery cable and touch it to the positive battery terminal. This will discharged the system capacitor and hard reboot the system.

that worked thank you for the help.

Nice work, we are here to help, please use 2CarPros anytime.

hi, i have a 2000 chevy venture that wont turn over, shorted the red- ppl wires in crank relay & starter turns over,relay, did not solve problem. no obd errors- checked fuses all ok, did the 10 min drill 3 times, any suggestions, thanks

Is thesecurity light on solid or flashing?Also do you have a multimeter to do some testing?

security light on dash is flashing, when key is place in ingnition light goes out, yes i do have meter, side power door did not work i think at same time, was working on door lock before all this happened ?????????

when doors are locked light is solid, when using fob to unlock light flashes, key in ignition light goes out

So is the light on after unlocking it with the remote and the key in the run position?

no, the car is locked and secure, the light is solid--when unlocked the light flashes---when key is in ignition light goes out

Did you have the battery tested?Also made sure the battery cables are clean and tight?Also take your multimeter and see if you have two ohms or less from ground to the negative battery cable at battery.See if you have battery voltage at the purple wire with the key in the start position.

no voltage on purple wire when key in start position, when red wire and ppl wires shorted the starter turns over---guessing the battery is good

Alright at the ignition switch you should have battery voltage at the red wire at the ignition switch.Then with the key in the start position the yellow wire should have battery voltage.Then at the right side of the dash fuse panel the pcm/crank fuse should have power to both side of that fuse with the key in the start position.Let me know what you find there and we will go from there.

When key turned to start position I hear clicking of starter trying to start an engine - lights are dimming. Battery is ok I tried battery from my wife's car with same engine did not start. Car was originally diagnosed with broken head gasket. Last 3 months was cold so car was in garage, not used. Level of oil is higher than max so it proof head gasket problem. Few days ago when temperature was around 60 I started, I drove out of my garage, and ran engine for while until temperature of engine rose to half of scale and I turned engine off. I did try start again and engine did not started. I replaced starter because I had issue with it before (intermittent did not start, if I did hit it was starting).
Question: Is possible some way to move engine ?

yes there is voltage at both sides of fuse pcm/crank when in start position

If you have a bad head gasket, that shouldn't stop the engine from turning unless one of the cylinders is full of coolant. Try removing the spark plugs to see if the starter can crank the engine then. If it does, check to see if coolant comes out of any of the cylinders.

Alright at the neutral safety switch the pink wire to it should have power then when the key is in the start position the orange with a black stripe wire should have power.

voltage on the pink at the neutral safety sw, none on qr/blk at the crank relay

The orange with a black stripe wire i was asking about was at the neutral safety switch with the key in the start positon it should have power along with the pink wire at the neutral safety switch.

i did typo, pink has voltage at nss, does the or/blk wire go from nss to crank relay, if so it does not have voltage

Yes the orange wire with a black stripe goes to the crqnk relay.In the park and neutral position the pink wire is connected to the orange with a black stripe thru the nss.Sounds like thats not happening.Try it in neutral just make sure the parking brake is set and works.Also chock the wheels to stop rolling.

When I try to start the vehicle, the lights, radio, etc. all come on. When I turn the key to start nothing happens no clicks, the lights don't dim, its as if its not even trying to start. This only happens periodically and then the van finally does start.

There is one of three problems, the starter, starter relay, or the ignition switch.

When this happens, I need you to check if you are getting power to the starter. Have a helper turn the key to the start position while you check for power to the smaller wire on the starter. You should get 12 volts. If you do, the starter is most likely bad. If you don't, go to the power distribution box and locate the starter relay. Remove the relay and see if you are getting power to it. If you have a relay in the system that has the same part number on it (and you should) switch the relays to see if that changes anything. If it does, get a new relay. If not, then you need to check the ignition switch.

Let me know what you find or if you have other questions.

its been awhile but heres what i found,no voltage on or/blk wire with car in park or neutral, so i decided to replace the nss,it did not help (on old sw the 2 bottom outer pins had no resistance or a good switch,dont believe i needed to replace it)-- i later found the or/black wire open from outside the connector of nss to crank relay (looks like 3 ornge wires at nss connector, i believe i have the right one) jumped pink wire from nss to crank relay but nothing happens, do the connectors at nss have to be plugged in?? ideas??

When you replaced the nss did you adjust the new one you put in?If you have power going into the nss you should have power pass thru it in the park or neutral position.

i believe i found the problem, the wires coming from the nss were
broken ten inches from nss---problem is 2 light green wires and 2 black wires with white tracers are in the package, how do i determine what gr to gr or blk to blk, thanks

For the start circuit the pink wire is in terminal g at the nss connector and the orange wire with the black stripe goes to terminal E at the nss connector.Is there other wires broken at the nss connector?

There is a wire diagram for the nss connector showing what colors go to which terminals.

the needed splice is away from the connector, on the 7 wire connector to nss there are 2 lt/green wires (c&F on plug), how do i make sure i make the right connection to each other,---also there is a blk/wht on 7 wire connector (D) and a blk/wht on a 4 wire connector-- in both cases im just guesing what wires i would splice together,

So are you just confused on which black and white wire goes where on the nss?Where does the 4 pin connector go and which wires are you trying to figure out there?I belive the wire diagram i posted shows all the nss wires.

sorry the diagram is fuzzy and not sure what im looking at. i know where the connectors go. its just that i have 2 blk/wht wires from a group of maybe 40 wires (blk/wtwires were cut mid point between 40 wire group & nss), what blk/wt wire goes to the 4 pin conn on nss--- what blk/wire goes to 7 pin conn on nss---one wire going back to the main 40 wiring harness looks like its going to ground(1 ohm), does it go to 7 or 4 pin conn.---7 pin conn on nss has a blk wire with letter "D" on it
--the other blk/Wht wire going to main 40 harness has 3.7ohms on it

The connector C1 terminal D that black wire with a white stripe goes to a ground left side of engine.So once you narrow that down the other black wire with a white stripe goes to connector C2 and that wire goes back to the pcm computer.

Went to go start the van and would not turn over. The batter is good and the connections are clean. Checked all the fuses everything is good. Removed the starter and had it tested, starter was bad so I put a new one in. Still turn the key nothing, all the power in the van comes on but the starter wont turn over. The relay sound like it is working. It seems as if the starter is not getting power. Tested the volts to the starter and it is getting full power. How do I test the ignition switch that goes to the starter? Or what else could be causing it to not come on?

I emailed you a trouble tree and a wire diagram for no crank no start starter solenoid no click.Your security light doesn't stay on or flash does it?

The security light was on but it is not anymore. When you turn the key the relay clicks but there is no power going from the relay down to the starter.

If the security light isn't on and it's not starting then you need to print up all the stuff i emailed you and follow it down and trace the problem down.If you need any help or have any question's on it let me know.

can i get that diagram i have same problem let van sit put new battery in now security light goes back n fourth between security and battery its a 2000 venture wont even try to turn over jumped starter at relay with ignition on it starts then dies

The engine wont start with the security light flashing. I wont try disconnecting the battery and letting the car sit for 30 minutes then hook it back up again. Lock and unlock the doors using the remote.

Please let us know what you find. We are interested to see what it is.

Cheers, Ken

ok trying to figure out a no start/no crank at starter relay i have power on red main wire ,key is start i get + power on both the nss wire orange and black and the the pcm wire yellow and black ,, the pcm shoud be a ground signal correct , at ecm i have power coming in on the purpale in to i think it 23 or 76 i might have them back words but postive going out on the yellow black
