as stated above..

 

its a possibility, but bad grounds usually make a rough idle, poor top end, missing, ECU quirks... stuff like that

 

i dont think so...bump also.

 

IF the grounds for the ECU were left detached then the car won't start. Those grounds are on top of the engine and only accessible if the throttle body is removed.

Or if the ground that is located on the long bolt for the starter is left off.....the chances are also slim and none.

Or if you take your coil assy and rest them on top of rags or a piece of wood the car is guaranteed not to start never ever.

But if your talking about that puny little ground that attached close to the wiper motor...no.

 

are the grounds under the TB visable with the TB on?

 

No. It's attached via a round connector to the block. You have to take the throttle body off.
It's highly unlikely a bad ground would make the car not start. Try check for the obvious(depends what it does when cranking): If it cranks: check engine fuse (under dash and 40A fuse in engine bay, AFM connector came off. Jump the yellow connector on the passenger shock tower , turn ignition to "on" and listen if the fuel pump is running. If it does NOT crank: check battery.
A bad ground just cause all sorts of weird **** when the car is running.

 

sorry for the dumb questions, but what does it mean to jump the wire?

 

To jumper.........a piece of wire connecting one socket on the plug to the other. As in strip a piece of wire on both ends and insert one end of the wire in one socket of the plug and the other end of the striped wire into the other socket on the plug. It would be best if you crimped a spade on each end of the striped wire....but not a neccessity.

 

yes it happened to me the other day

 

If it is a bad ground off the starter then the starter will not get enuf juice to turn the car over. or something else isnt grounded and it will not get power.
