Question about Cars & Trucks
Turn on the key, but nothing at all. What to try next?
Lots of possibilities. Do your headlights come on? If not check your battery terminals. Next suspect is the starter relay or the starter itself. You may have to take it to the shop.

Testimonial: "Thanks for the feedback. The problem turned out to be severe corrosion to the battery negative/ground wire. Cleaning the surfaces brought it back to life. Replacing the entire cable today. Thanks...."

If you nothing dont even try to turn over check your battery wires loose or dirty connection. Most likely dirty terminal connections.

You can jump across the celonoid on the starter. If the engine turns over then your problem is either the celonoid or the starter switch.

It could be your neutral safety switch. It could be the starter relay which is located in the fuse panel box. It could be the smaller wire going to the starter could be loose or corroded.

try jumpin it to double check its not the battery. if not check spark plugs. if that doesnt work then id safely say you'll either need a new starting motor or a fuel pump

SOURCE: will not crank turn key
Check fuse # 28 (15 Amp) with a test light. (Located in the Power Distribution Center (PDC) on the left side of the engine compartment) It should have power only when the ignition switch is turned to the START position. If there is no power there, then you probably have a bad ignition switch. The only other fuse involved would be fuse #8 (40 Amp) which is also in the PDC. If this fuse is blown a whole lot of stuff is not going to work - not just your starter. The starter motor relay (Also in the PDC) is controlled by the PowertrainControl Module. The wiring diagrams show it as a 5 pin relay whereonly 4 of the pins are used. If you check for power and ground at the connector pins for the relay, there should be one pin that is hot all the time. This is the power from fuse #8. a second pin should be hot with the key in the RUN and START positions. This would be the circuit running through fuse# 28. One pin should have continuity to ground (your test light should light up if you hook it to the battery positive terminal and probe this terminal.) This is the circuit that goes down to the starter. The 4th pin will have no continuity to anything at all until the ignition is placed in the START position, when it will have continuity to ground. This is the relay control circuit from the PCM.
If you dont have power at the relay connector as described, then you must repair the circuits between the fuses and the relay. If you don't have the grounds as describedfor the starter circuit, you ether have an open circuit going to the starter or a bad starter. If you are not getting ground on the control circuit from the PCM, it could be several other things causing your no-crank problem. It could be an open circuit between the starter relay and the PCM or it could be that the PCM is not allowing an engine start for one reason or another - The PCM will have to be scanned to find out what the problem is.
