Vt 304 won’t crank

[skippy73]

try getting in the car and then lock it with the remote so that the security light is flashing.

Then turn the key to position 2 and see if the light is off. If the light is on then Its key and slip ring related. was the new key done with a tech2 or a mister-minute job?

ok hoped in the car an locked it, red light flashes, when i turn the key light stops flashing, so it’s not the key or slip ring

in the engine bay, test your start relay

98 vt commodore, cant start car without bypassing start relay.

HELP! I have a 98 VT, one day it just wouldn't crank. I replaced the starter motor, ignition barrel, ignition switch, start relay, fuses, keys, immobiliser, park/neutral switch... When i turn the key to run i can hear something buzz in the engine bay then nothing. I now have to bypass the...

yes it starts if i bridge the starter really. I was thinking of just buying a kqs-q6c pushbutton start kit,

Why waste money on this to start with.....

@gtrboyy has suggested where the issue is.....But just to help...First replace the starter relay.....Logic tells you, you have power going into the relay area from the ignition switch and power going out to the starter from the relay area, but when the relay is in place, you have zippo.....So spend $20 or find another relay in the electrical system of the car, that isn't required to run the car and replace it...From there, use the key and see if the starter motor engages from the key.....You might be surprised it actually starts and you'll save yourself a few bucks in the process

ok i think i just tested the starter realy with multimeter
start realy using multi meter
not sure if i done it right but this is what i got..

87-30 key off 12.80v
key acc 12.30v
ign 12.30 v
key start 12.45v

87-85 key off 0.00v
key acc 0.00 v
ign 12.30
key start 12.40 v

30-86 key off 12.30 v
key acc 12.25v
ign 12.09 v
start 12.25 v

87-86 key off 0.00 v
key acc 0.00v
ign 0.06 v
key start 0.06

you should not have power at 85 with ignition in on position, if you did starter would always be cranking when ignition on reds or engine running (suspect test error)
apart from that all of your circuit seems fine
so poor connection at relay or faulty relay

surely you havnt wasted all this effort without swapping the relay first?
