Default No power to solenoid

98Hi Guys
Need a little help. I have no power to the started solenoid. This is a manual trans. I have power from the ignition switch to the keyless entry module. I have jumped the starter relay, the clutch switch etc, but still have a no start situation. Has anyone had this same problem, and if so what was causing it? I checed other threads, but did not find anything. has new starter also...Any help is appreciated.

See this post (HG replacement lights flashing car wont turn over)

It's for an AT but the attached wiring diagram should apply to your MT car as well.

In that case the wire to the solenoid was off.

Thanks for the reply. The wire to the solenoid is attached. I replaced the starter last week ans has been starting fine until yesterday. I have power from the ignition switch to the keyless entry module, but I am not sure where it comes out if the module at. There is no power to the starter relay, or clutch switch. I am thinking the module has gone bad.

Have you checked the starter interrupt relay?
It looks like you may be able to swap the headlight relay temporarily for a quick test.

hawg:

Attached is the 99 keyless/security wiring diagram, which should be similar to, if not the same as, your 98. It includes the wiring for the starter system.

Coming from the ignition switch, when in the Start position, there should be 12 V on pins 1 and 2 of the interrupt relay. Pin 4 of the relay goes to the security module, and if the security system isn't in some sort of lock down, that pin should go to ground, energizing the relay.

When the relay is energized, 12 V should go from pin 2 to pin 6, and from there to pins 2 and 4 of the starter interlock relay. With the clutch pressed down, the clutch switch should be closed, grounding pin 1 of the relay, energizing it, and closing the connection between pins 4 and 3. The 12 V goes from pin 4, to pin 3 and from there to the starter solenoid connector.

Although not impossible, the keyless entry and security control module rarely fail. It's more likely one of the relays is bad, or perhaps the contacts between the relay and the receptacle are dirty/corroded, which is not uncommon.

Also, make sure the clutch switch is closing and making a good ground when the pedal is pressed.

Hope this helps; let us know what you find.

Thanks for the diagram. I found if I jump the blue/red wire from the ignition switch directly to the red/ye;;ow wire on the starter relay it will start. doing so I eliminate the keyless entry module, so I am thinking that it is bad.

Looks to me like you eliminate the Interrupt Relay, Interlock Relay, & Clutch Switch with that one jumper connection. Maybe plain OM's schizmo will help narrow it down finer. I hate to bypass relays on these cars, for fear of overloading components upline which were only meant to carry the load of relay coils.

H-D is right. You're bypassing everything. That does not mean the security module is bad. It could be any of the bypassed relays and clutch switch, a bad connector contact or even a broken wire.

The clutch switch should be checked first. It opens and closes every time the clutch is pressed, so might be more prone to fail than the relays or module. It's also probably the most accessible component. I'd start by making sure that the switch has low resistance between pins 1 and 2 when the clutch pedal is pressed down, and that pin 1 has good continuity to ground.

Yes I agree, but I am not getting power out of the module to any of the other components. There is power to the module at the starter interrupt circuit, but nothing coming out. The keyless module just clicks.

Is there power coming out of the starter interrupt?
Have you confirmed the relay is working or not?
