 If you have the second ignition key's with you try it.  If not try this, it takes about 30 min to do. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself. Good luck and hope this helps, keep me posted, be glad to help.

SOURCE: 94 jimmy turns but wont start, I replaced the fuel pump and

Check to see if you are getting the correct fuel pressure at the rail. It takes at least 55psi to push past the propets in the spider assembly. Cold weather requires even more psi. You can test this with a cheap fuel pressure gauge from almost any auto part store.

I would also check to make sure the ground for your pump has a good connection, it should be located around your rear bumper in the center. A weak ground will dramatically kill your psi, but still push fuel to the rails.

There is also a problem with the "expensive" spider assembly of that truck. The spider assembly holds the single injector and has 6 tubes going to each cylinder. The lines going into the assembly are known to leak. If you take off the manifold you can easily see if there are any leaks from it, there will be wash marks where the gas has cleaned it. Instead of buying a new spider assembly, there are rebuild kits for it.

If for come to the conclusion that you need a new fuel pressure regulator, don't let them lie to you in saying you need to buy the whole spider assembly. You CAN buy it separately for around $40. If you have problems finding it at local stores, search for it online.

My Mitsubushi Space Star Car won't Start. What can I try?

spark plugs are deep in the head yet you should get all the the old fuel out first, stale fuel wont ignite and will also clogg fuel filter. you need a mix of atleast 70% new fuel even then its not good for the injecters. If its a manual gearbox a tow start is a quick fix although no go for auto's. cant be much wrong if car was fine when parked, plugs-fuel-filter and possibly fuel pump for sure. If that doesnt fix take plug out put in lead and crank engine to be sure you have spark even just put any plug you know works in lead leaving your plugs in engine just to check for spark y turning over engine looking for spark on plug good spark will be blue but any spark is good.

the security system need to be reset, plug your charger back on the battery then turn the ignition switch on and leave it on untill the security warning light turns off (about 10 to 20 Min) then turn the key to off wait 5sec then turn the car on it should be good to go, this solves this kind of problem 9 out of 10. good luck

Hyundai lantra 16 si w reg went out it was ok parked up last night went out in morning wont start now

First you have to determine if its fuel or fire. To check for fuel spray a few seconds of quick start into the air intake. If it starts and then stops. its likely a problem with fuel. If it doesn't start its likely spark or battery problems. Does it turn over?

I have had problems starting my vette i replaced the starter soloid that was shot then went to start it got nothing checked fuses replaced alarm fuse that was burnt out horm kept going off pulled made a...

first things first. if its the alarm system you wont have spark so check that first withan inductive timing light on one of the plug wires while you try to start it. if it was runnung fine before the solenoid fix its the most like cause. you will need to find a amnual online to figure out how to bypass the system or troubleshoot it to find out if it has a reset. next is fuel. if your getting good spark check to see if your getting fuel to the cylinders. if you have an electric fuel pump you may have blown the fuse in its circuit as well. start here and see how far you get. its always one or the other, either fuel or spark. good hunting.

1999 Infiniti 30 wont start. Disconnected battery for 20 mins. and it strated 4 times in a row. Then I set the alarm and turned alarm off and it wont start. Is this a security issue or a starter problem?

Sounds like it went into theft mode when you unhooked the battery and tried to start it multiple times. Most cars have some sort of SKIM key which is a key with a computer chip in it that is programmed to a module in the car. If this programming is lost by a battery diosconnect it usually needs to be reprogrammmed by a dealer. The reason it won't start is because the theft mode probably has the fuel or spark disabled as a theft deterrent.

'92 Park Avenue won't start or run.

When the Theft Deterrent Module (TDM), that is the core of the VATS system, cease to function, the security light could also stay off because it's the TDM itself that manage it. In my case that's what happened, the faulty TDM was recognizing the key, turning off the security light, activating the starter relay, but was not sending the fuel enable signal to the PCM.
There is a great write-up on how to completely bypass the TDM here: . This is what saved my car.
