5.0 Starter Problems

I just had this problem. And it was the ground strap on the back of the motor check it. Make sure it has a good connection. I hope this helps.

Could be a ground like stated or more likely is that the starter is just worn out. A lot of times people will confuse the two because they are similar. If you know for a FACT that the battery is 100% good to go, then what happens is that the starter has just lost it's strength and has difficulty in turning the engine over. If after connecting the starter to battery juice directly and it acts weak or turns slow, than it's time for a replacement. First though check that grounding strap or that the starter is clearly bolted to the engine well, then the battery, then the starter.

BTW, the starter should be towards the rear of the engine on the underside of the passenger's side.

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.

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.

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.) 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.

4.) 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 the relay is bad.

5.) 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.

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.
