I have a 2001 Plymouth Neon. It is a manual transmission. When I go to start it, I turn the key, all power & lights on the dash come on except the oil light. It makes an annoying clicking noise, that lasts from 15 minutes to an hour, then the oil light comes on & the car will start. It even does this if its being jumped. But, if turn of the car, after the engine has been running no matter how long, as long as you turn the key immediately back to the on position, no clicking & you will be able to start it. But when the clicking is going on, it comes from the fuel pump & black fuse box under hood. Any ideas?

If the battery has gone dead, it could cause the security system to go into full lock-up mode. If it has locked up the accessories will work after the battery is charged back up , but the power to the starter will be cut off and it wont turn over. You need to do the 30 minute learn procedure. A GM dealer will print it out for you and you can do it yourself. It's very simple if you follow the procedure exact. hope this helps and good luck.

Sounds like carbon build up on the contacts inside the electrical ignition switch which is not the key cylinder. Its located on the lower steering coluum if coluum shift or if you have a floor shift it will be inside the console

If the oil pressure switch has two wires on it it may be one that shuts down the pump. I'm not positive but I think it completes a ground circuit, not the hot side though (but may run through a relay.) There should be a pump relay under the hood with a group of other relays. I don't have a wiring diagram for your car but you can get a basic diagram in most inexpensive manuals. They wont usually give you locations but at least you can get an idea of how the system works. There usually is a fuse. If the fuse block is not labeled, use a test light and probe the back of every fuse for power with the key on (takes about ten minutes and faster than trying to find info) change any that are blown. The most likely culprit is a relay, so after testing fuses look for it. (usually on drivers fender or on right side near firewall.) Worst case, trace the power lead all the way through the harness 'till you find where power begins.Testing is important here...I could give you much better info if I was there to do it for you. Most important is to stay "on track" till you find the place where power ends. Don't jump all over the place or you will end up doing an incomplete test.

try cleaning the connector that goes to the fuel pump, sometimes they corrode on inside. If that does not fix, test the wires feeding fuel pump with a multi meter until the condition shows itself again, if voltage drops to zero or very low then wiring problem, if voltage is unchanged with problem and fuel pump is not working and connectors are all clean, try replacement of fuel pump.

If it is a single click, the problem lies in the starter solenoid or relay. If it is several clicks in succession, the battery may be low or there may be a loose cable. ---------- also try this :-- Please make sure the battery is fully charged before doing this test! Also make sure all the connections on the starter, battery and cable ends are tight and clean! this is important!! This won't be fun to test but it will tell you if the starter is good or not. Crawl under the car. (Make sure you use the proper jacks and jack stands!) find the end of the starter (not the end that is attached to the bell housing) and find the solenoid switch. it should have 3 bolts on it. Two large ones and a small one. The top large wire should be the positive battery cable, the bottom large wire should go into the starter and the small wire should be from the ignition switch. Take a wire and hold it to the top large wire on the solenoid. (be careful of the other end of that wire when you have it connected to the top large wire of the solenoid! don't ground this wire. it will turn out badly. take the other end of the wire and touch it to the small bolt on the solenoid end. If the starter is working, the solenoid should engage and the starter will turn. If this happens it is most likely the ignition switch. If the starter doesn't turn, the starter could be bad. ==== Starter Relay Test
Place transmission in Park.
Apply parking brake.
Check for battery voltage between starter relay battery terminal and ground.
Connect jumper wire on starter relay between battery and ignition terminals.
If engine does not crank, connect a second jumper wire to starter relay between ground terminal and good ground and repeat test.
If engine cranks in step 3, transmission linkage is misadjusted or neutral safety switch is defective.
If engine does not crank in step 3, starter relay is defective.
Follow this step by step and you will pinpoint the problem.
