1995 Oldsmobile 98 no crank no start

starter checked by the big three pass two failed one something about terminal R. Which was loose.

When you turn the key to the run position is the security light on solid or flashing?

it's solid then goes out.

got court in a few hours better turn in pick this up later.

Doesn't sound like the security system is the problem then.Do you have a multi meter to do some testing?

yes

going to game will return after STL wins!

Alright out of the ignition switch the yellow wire should have battery voltage with the key in the start position? All these tests will be with the key in the start position. Next find your ant theft relay behind left side of dash above the inside fuse box.The yellow wire should have battery voltage both of them?as well as the purple wire to it?the yellow wire with a black tracer should have ground to it?Then your neutral safety switch should have power to the yellow wire and the purple wire?Then at your starter there should be battery voltage on the purple wire?Remember all these tests with the key in the start position.

ant theft relay is this the same as the starter enable relay. If so i check this and did not get any reading on anything both yellow wires purple wire nothing.

this car is not at home it is several mile away, sorry for taking so long to get back with you.

Yes the anti theft relay should be the same . Do you get power out of the yellow wire from the ignition switch with the key in the start position?

No. While checking with vom no reading out of either wire. This is one hard set of wire to get to!

So the yellow wire at the ignition switch with the key in the start position doesn't have battery voltage?

No.

Alright the red wire to the ignition switch should have battery voltage all the time?If so looks like the ignition switch is bad.If the red wire doesnt have battery voltage to it then check the fuse number 2 in the underhood fuse box. Its a 60 amp fuse?

Retested. Went back and rechecked wires @ starter enable relay, this time used test light and turned key to cranking position not just in on position, got light from one yellow wire and purple wires.

At the relay the purple wireshould have battery voltage. The yellow wire terminal c1 should have battery voltage with the key in the start position?the yellow wire terminal a2 should have battery voltage with the key in the start position? The yellow wire with a black stripe should have a ground to it with the key in the start position?

Yellow turns on test light, purple as well get nothing from yellow wire on other side. Also can hear relay click.

Need to know the terminals that there is power and no power your my eyes and hand's.

It seems as though c1 a yellow wire c2 the purple wire both test good I get nothing from a2.

Check ignition fuse under hood it ok.

While cranking see if terminal a1 yellow wire with a black stripe is getting a ground?

I get no reading from yellow/black wire with test light or vom. Maybe I am doing the test wrong. I retested all wires get 12.25 volts on both yellow and purple wires only when switch is in the crank position. With switch only in on position there is no voltage.

The yellow wire with a black stripe your looking for a ground not power on that wire while cranking.

No voltage to yellow/black wire. Did recheck all wire 12 volt to purple wire while cranking 12 volt to both yellow wires no power to yellow/black. What I did see was while checking the wires with switch in crank position light come on with switch fully engaged the test light would go out???

Not sure what you mean by with switch fully engaged the test light goes out?Also for the third time the yellow wire with a black stripe should be a ground not a power.If your using a test light you would hook up the aligator clip on the test light to power.Then test the yellow wire with a black stripe the test light should light up with the key in the start position? .

When I say fully engage that is the key is being held it the crank position and the test light comes on and then goes out.

So how is that ground doing?

Thanks for your help changed neutral safty switch car started like new. Thank you so much!

Your welcome glad i could help.
