Ignition to Starter Cable

[UpbeatFish]

In all honesty, if your as you put it "a huge electical dummy", then your better off either finding someone in your area that knows what they are doing to come over and look at it or give you a hand with it or take it somewhere. Its to hard to explain if you are not atleast somewhat familiar with the systems and how they function....

guess i got to learn the hard way
either way im going to learn how to use it

you didnt start knowing the system right away

so ill just read up and get back to it

I volunteer to take a look at it, but you'll have to bring the car to me. Bellflower isn't too far away.

I've had to bypass the alarm and fix cold start/idle problems with my car as well. I think you should worry about fixing the starting problem first, then diagnose the cold idle problem after you've fixed it. Best to deal with one thing at a time.

thank you

it doesnt start by turning the key but it starts when i connect a power cable to the starter. so the starter is good. and the bat is good

So you still haven't checked the small wire on the starter. Clearly, there isn't switched power. You have a starter relay that has to close. You have theft deterent that allows that. You have a neutral start switch that needs to close, or the power is interupted. You have to find out what is open(electrically).

And yes, their is a relay in the solenoid, from the earlier sidetrack.

And the ECT sensor is not a part of the cranking circuit. It will crank regardless. It might not fire up, but that is a different symptom.

I believe his car is a 5-spd...he should probably also check his clutch safety switch.

I had the same problem, that was fixed with a separate relay to the starter solenoid, with 12ga power wire coming straight from the battery. This works because the old stock wiring very often can not supply enough current to the solenoid. It is important to leave the original starter circuit wired up so the ECU gets the signal that you are trying to start it. That's why it stumbles when you start it with a separate power wire. The ECU adds extra fuel to aid startup.

If you do this modification, you must either push in the clutch pedal when starting, or bypass the switch to complete the STA circuit. Otheriwse, you can turn the starter without pushing the clutch in, and you will have a hard time starting it.

yeah i got all the stuff to do this mod
30 amp relay and such

but i didnt understand what you mean by the last part.
i thought it was only power >relay>starter wire>ground

That will work, but just be sure you push the clutch pedal to the floor when you start your car. Otherwise the computer/ECU won't know you are trying to start it.
