Did you check the fuel pump relay ? The relay gets power from a fuse and also from the PCM relay. The computer grounds the relay to turn it on for 3 seconds when you turn the key on, then only after the computer "sees" RPM or oil pressure.

Where will I find the ignition cylinder tamper switch on a 98 lincoln town car


Its just about impossible to bypass. You would need a key that matches the old key chip cut to the new tumblers. Each key has a chip in it that the computer looks for.

Trans leak from dip sick


Could be damage from jacking vehicle to change tires. Sometimes lift kits are installed to match oversize tires and clearance might be messed up by putting on smaller tires. Any chance dipstick was already leaking?

1998 ford explorer alarm will not let car start door locks not working


The Security system will activate if the Battery is below standards. Have the battery checked. Even if you jump start it, as soon as the jumpers are removed the charging system may not work or the engine may die.

If you have another ignition key, try that. The ignition key has a Code in it and if it does not match the Codereader, it will not start.

Anti_Theft System


I am not quite sure what you are trying to do. The anti theft is always engaged as there is chip in the key that must match in order for the vehicle to start. What do you want to accomplish?

Security problem


Can you please tell me what part was replaced on you ignition system.
If you have changed the ECU or the IGN key switch they need to be fitted in matched pairs as the key switch is match coded to the ECU
Unless you purchase a brand new one that will be blank but must be coded by the dealer or someone with the correct software.

Inside the key is a small chip that tells the ECU it is a match & lets the car start.
The mechanics of most key switchs can be replaced but you must put the chip from your old key into the newly fitted key.
Some cars like Mercedes have the key switch coded & the key so they talk to each other & they must also be coded to the ECU as well.
Nothings ever simple is it.
