on problem? we replaced the battery, starter relay, and voltage resonator. It will only turn over when 2 screwdrivers bypass the starter relay. Any ideas of what else could be wrong?
 
it has something to do with the ignition. you need someone with a multitester who knows how to use it. You start with the keyswitch and work your way down.
 
Check your grounding. Your ignition could be it but don't replace it just to find out that your not completing the circuit due to a ground wire. Do some checking first.
 
On the starter relay there is a third wire. Ck the wire to see if you are getting power to it when the key is in the crank position. If you are getting power to it sometimes the relays have 2 small terminals it may be hooked up to the wrong one. Here is an easy test. Take a jumper wire from Battery positive and touch it to the small terminal on the relay. If it cranks then you probably do not have power from the small wire. That small wire comes from the Neutral Safety Switch. Do you have a stick or an automatic trans. If it is a stick then the NSS is attached to the the clutch pedal near the top where the pedal pivots. If is an automatic trans, then put the trans in neutral and try cranking it, if that does not work then put the emergency brake on real good and apply the regular brakes and put the gear shift lever in all different positions and try cranking. If vehicle fails to start either you Neutral Safety Switch is bad or the wire is broken from the NSS to the starter relay, or ignition switch is bad or the wire from ignition switch to the NSS is broken. If you need and more help just wright a comment on this page and I will reply in a day or 2
