I can only start my car from the solenoid with a screwdriver. It is starting to get anoying. I havn't really tried fixing it yet; I would just like to know where to start looking.

It's one of 2 things, the solenoid is bad "about 13 bucks" or the key igniton is bad "again about 13 bucks"

when you turn the key does the solenoid click? if so it's the solenoid

It could also be the clutch switch if there is one. Or the method of jumping the switch may have failed.

Here's a checklist:

Since some of the tests will bypass the safety interlocks, make sure that the car is in neutral
and the parking brake is set. Becoming a pancake isn’t part of the repair process…


Check battery, terminal connections, ground, starter relay switch (also known as solenoid) and
starter in that order. Battery cables with the replacement ends that clamp on the cable with 2 bolts
are a know problem source.

A voltmeter is handy if you are familiar with how to use it to find bad connections. Measure the
voltage drop across a connection: more than .5 volts across a connection indicates a problem.

See http://www.fluke.com/application_notes/automotive/circuit.asp?AGID=1&SID=103
for help


1.) Will the car start if it is jumped? Then clean battery terminals and check battery.

2.) Check the battery to engine block ground, and the ground behind the engine to the firewall.

3.) Jump the big terminals on the starter relay next to the battery with a screwdriver - watch out
for the sparks! If the engine cranks, the starter and power wiring is good. The starter relay is also
known as a starter solenoid.

4.) Then pull the small push on connector (red wire) off the starter relay (Looks like it is stuck on a
screw). Then jump between the screw and the terminal that is connected to the battery. If it starts,
the relay is good and your problem is in the rest of the circuit.

5.) Remember to check the ignition switch, neutral safety switch on auto trans and the clutch
safety switch on manual trans cars. If they are good, then you have wiring problems.

Typical start circuit...

model cars.

6.) The starter may be hung, loosen up the bolts that hold it on, and give it a good whack with a
big hammer. Tighten up the bolts and try again.

7.) If that doesn't work, use a jumper cable from the positive lead on the battery direct to the
starter post where the big wire from the relay connects. If it cranks then, it is the power wire from
the relay gone bad. This will be hard to do, since there isn't much room to do it.

8.) Pull the starter and take it to Autozone or Pep Boys and have them test it. Starter fails test,
then replace it. If you got this far, the starter is probably bad.

thanks for the info. I feel its the relay. I don't know exactly what to change if this is bad.

you can just buy the regulator, and change it, it's on the fender wall and has wires going to it from the starter and battery,
