please help me diagnose this problem. 90 ef hatch with a 94 z6 running obd1

turn the key and the fuel pump primes, everything is normal. as soon as you to go start the car and engage the starter, it makes a click sound and looses all power, you have to disconnect then re connect the battery for it to work again. any ideas??? i dunno how related it is, but if the iacv is plugged in, it constantly hums and draws power. is there a short in the wires somewhere??? thanks for looking, this is on my old car i sold to my friends sister

 

is the battery charged up? ususally it cuts all power to everything for a second to start the car

 

get the battery tested. and the alternator tested. free at autozone or murray autos. it might be one of those

 

check all grounds, or any exposed wires, anything that looks like it might be in rough shape. Concentrate on the wires around the starter and whatnot

 

check the ground at the trans. they can get very corroded and cause that.

 

Poor battery ground

<-- Battery in the rear, had power for Key On, but couldn't get the car to start for the hell of me. Turned out the spare tire stem had corroded over

I second that,

 

yup yup check the grounds...that happens when something isnt grounded right also be sure to charge the battery because it will drain the power out thats for sure if you keep having to do what you say you been doing...MOE@HYPER16VALVE...

 

ok so ill check the battery connections, also the starter connections too probably
