Question about Jeep Cars & Trucks
Hi, i own a 1999 xj jeep cherokee auto 4 litre and what i believe is the engine imobilizer light came on one morning as i tried to start it to go to work, i cannot start it even though the engine turns over and none of the jeep dealers in the south queensland area want to touch it as it's duel fuel. it was running perfectly the night before the morning it stopped working, it is a very nice vehicle and an engine swap is looking like the only way to bypass the imobilizer and computer , i like the features that the car has got and really don't want to have to that avenue if possible. any sujestions would be greatly appreciated, thank, bryan.
I love posts that have the word bypass.
99XJ. (why not join the forum for Cherokees)
that dealer just gave you a wave off for nebular reasons.
the truth is its illegal for him to do what you ask.
never ask a dealer to bypass something like this. it's futile.
but do feel your pain, that really sux.
on the newer jeeps, the IMMO NOT bypassable.
(one guy bought a PCM that has no IMMO option and got that to work, imported from another country.
read this security page here.
Once the VTSS engine no-run feature has been enabled in the PCM, it cannot be disabled.
1998 you can
If you are needing to DisArm the Factory Alarm:
Find the PURPLE / YELLOW (-) wire located in the Driver Kick Panel / Door wire harness (harness that goes into door)
Ground the PURPLE / YELLOW (-) wire
there is a company in Florida that will change your PCM
seems you lost your 3 key fobs.
always have 3, 2 are required for you DIY to make a 3rd.
in the USA we must tow the pig to the dealer.
and say, give me 2 keys and make it work
then go home and make a 3rd with DIY key, even a no fob button key works. cheap. (transponser only key) i have mixed brand keys running all fine. That is the way.... if that its not possible for you.
i bet you didnt ask them that. right> get 2 keys working.>
so the only way to bypass is to do research on
How to get remote start working, they have the cure.
or the Florida ECU shop. ( i lost the link, dang)

Climate control is the heater/a.c. systems. Multi-Point fuel injection is the type of fuel system the car has. Vented brakes have holes in the rotors to help cool them during heavy braking. Immobilizer is the anti-theft device. Electronic traction control will transfer the power to the wheels so it doesn't slip or loose traction. ABS is Anti Lock Brake system. This is so your brakes doesn't lock up during hard braking. No. 7 is the suspension system for a good ride and cornering. Not sure about No. 8 though.

I'd suggest the ignition control module, however I'd have a certified mechanic check it out just in case...

This is usually how it happens with Electric Fuel pumps. They either work or they don't. When you turn the ignition to on you should hear the pump engage and pressure up. If you don't most likely your pump is faulty. You mentioned that it did this after a freeze. It is possible that you have a frozen fuel line, Supply or return, will also cause this problem. The best you could do is move the vehicle into a garage and warm it up above freezing to allow the lines to thaw. A lot of time we get moisture build up in a tank without even knowing it. Cold fuel is supplied to the motor through the pump but the return line returns warm fuel and in a cold environment this will or can cause condensation to form in the tank and lines. Also bad fuel from a station will cause this issue. It doesn't take much with all the additives they put in fuel today. They sell fuel additive that will remove this moisture if that is the problem. try warming the vehicle up and thawing the lines. If this proves to be the issue you'll need to drop and drain the tank and lines to clear the problem or try a fuel additive to remove the moisture.
