The red immobilizer light is staying on,the engine cranks but wont start..


You then have a ant-theft system problem an need to have the vehicle checked for DTC'S - diagnostic trouble codes . The ASD - relay supplies power to the ignition coils an too the fuel injectors .The ASD- auto shut down relay is energized by the engine computer - PCM . With the red anti-theft light on the PCM will not turn on the ASD relay cause a no start condition . You can check fuse an relays all you want ,not going to do any good . You need to see what the ant-theft systems problem is .

My 2001 pt cruiser will run ten minutes stall and wont start back no fire at all but will start back up normal after a couple hours and then run ten mins and stall out have replaced coil pack cam/crank...


A mechanic would check the ASD relay and the coil for voltage when the engine will not start.
You might also want to check the computer for trouble codes.

This is my 5th xj and have solved just about every problem....This one is a wrench thrower. 94 xj Wont Start. I replaced the ignition switch, checked fuses, replaced TPS, Cleaned relubed NSS. Battery new,...


I'm not to familuar with this year, but hear are some ideas. First the starter relay. check the relay to make sure it is good. easiest way is to swap it with another one around it. Also check to see if there is an ASD relay(auto shut down) If there is you will also have to check this one. the power runs threw the asd to the starter relay. check for power at the relay sockets, with the key in the start position you should have power at 2 sockets. The other sockets, 1 will got to the stsarter solenoid, the other to ground.
Let me know

2007 jeep Cherokee wont start. Radio comes on and power windows work it just wont turn over


It could still be the battery....It may not be strong enough to start it but you will still have enough to operate windows and radio....It doesnt take much power for radio....or windows Unless you move the windows constantly then it will run battery down quick.....Check battery voltage and battery connections...Also jeeps have a ASD relay which means AUTOMATIC SHUT DOWN...This could be a bad relay.........This is under hood at fuse Power Block Box.....This could of course be the starter also...Check wiring connected to starter....Sometimes it will vibrate loose and it will do nothing....And the crank sensor will cause it not to start....It is on the passenger side of engine block under and at back of engine ...You cant miss it if you can get under it.....It has another relay the same size as the ASD relay...You can test the ASD relay by switching the two and this will tell you if the ASD relay is blown...If this doesnt change anything and still wont start it is not the relay.
I am chrysler tech and have jeep manuals.......I can help you through this....I need engine size and exact problem....Does it turn over at all ?..How many miles on it ?..And does the dash lights and gauges operate when you turn the switch on like normal...?..Make sure it is in park and your foot is on the brake while turning it over.............................................Metalpoet

It want start


Double check your connections and replace the fuse. That sound usually indicates there is a short.

My 98 dakota wont fire


Check your Automatic Shutdown Relay in your fuse and relay box under the hood by the battery. The power supplied to the fuel pump, ignition coil, fuel injectors,  and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD); the idea is to shut off fuel pressure and the ignition systems when the key is turned off to prevent fires, dieseling, and other problems.
The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, the logic module cuts power to the ASD, which in turn removes power from the fuel pump, ignition coil, injectors and those parts of the power module.  This causes the engine to shut down.

The logic module monitors the relay driver.  If it senses that the relay driver is not responding correctly it will trigger a code. If the logic module does not sense an absence of current when the circuit is open, or 12 volts DC when the circuit is closed, it knows that the circuit is open or shorted, and triggers code 42. Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start. Good luck and hope this helps lead you in the right direction. Hint: The ASD can be triggered by a broken wire or short in another place, e.g. the fuel pump.
