SOURCE: chrysler 3.3 vin r v6 mini van, starts then dies

Charlie. You have replaced the ECM on your van?.
Kedwin,, Your problem is, the computer on that 3.3 L.
Need to be programed with the VIN nember of your car.
The Antitheft System will disable the injectors due a incorrect VIN, Bucause the body computer is not recieve the correct pasword between 5 seconds after start up.
YOU have 2 options. 1 get a ALOHA Smith. some of they have the computer required to program ECMs.

The other option is: Get a new ECM from the dealer, They will program if ask for that.

NOTE:::::: Other way is . Put the body control module with the computer from the same car.

OK... I hope this work for yours.
If NOT letme know I can look for more information.
Thank you.

SOURCE: fuel pump relay gets hot on a 1995 s10 blazer

Most likely a bad connector on relay or the fuel sock needs to be replaced. if the sock is plugged it would cause the fuel pump to work hard and cause it to heat the relay and make it hot and removing it will cause it not to run. check the connectors to the relay see if they are opened up in the female socket if they are use a dental pick to close them up with. otherwise replace fuel pump and sock at that age with the alcohol in fuel it's killed the pump and sock.

Why does 91 dodge dakota shuts off power to coil after driving


The auto shut down relay controls power to the coil and fuel injection so if on power is at the coil once the engine dies this is normal check cranking it should return but no spark then test the crank shaft sensor iit is on back of engine passenger side bolted to block.

Motor shuts down


stalls,
lots of causes of stalls, i have a list of over 50. could add to it easy.
Portuguese = Bobina (ignition coil)

Jeeps have a RELAY called ASD, and that is its job to SHUT Down.
here is a list.
1: check all fuses first on both fuse boxes
2: battery charged to 12.6v, rested. (good spark plugs not 18years old
3: crank and see ASD close, if yes, then see if it drops out with 5 seconds cranking, it might drop out in 2 seconds.
this is the 2 second rule.
when you see it drop out , that means the ECU sees ERRORS.
bad spark , bad CMP, bad CKP or Immobilizer errors. SKIM.
4: we then connect any OBD2 scan tool to the OBD2 DLC 16pin
connector , and crank again for 5 seconds.
the scan tool will (may) show DTC errors, these errors tell you
WHY the ASD was dumped. (stalled)

ill stop here, as we need above facts to proceed.

Autoshutdown keeps turning on


which engine???????????????????????????
ASD is tricky on jeeps.
The Auto shutdown,relay.
what is it , how does it works is covered in the fsm. read it.
http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service
The ECU runs this RELAY, and if the ECU sees a gross error
it shuts this down, and the schematic there is clear as to what.
both spark and fueling.
here is what can drop it out.
1: crank sensor.
2: cam sensors or TDC ,etc.
3: sees spark dead or weak.
4: Immobilizer active. (failed)

as the book says , make sure spark is good for the 2 seconds cranking. (not after the 2seconds)
the ECU is programmed like this.
user cranks.
ECU creates spark,, using the crank/cam sensors at the time base
for 2 seconds
if the spark read back fails or the 2 sensors fail, the ecu shuts DOWN.
this is for fire prevention.
most other cars just cut the injectors, but not jeep
the drop the MAIN ASD relay.

using the check engine light flash codes, you can see which of the
3 failed, cranking for 5 second and releasing the key on all cars.
1996 and newer a scan tool is use to same effects.

now the 64,000 dollar qustion,
see page 8w-30-4
why does the ASD KILL THE IGNITION coil. easy.
1: it only guess it 2 seconds to make spark
2: if it cant,. it then drops the relay. killing fuel too.
3: this prevents the the crash and burn you see on TV.

so its 2 second permissive system. (or 3?) i forget exact seconds, its in then book and is short.
many dont know this. but is a fact.


now the flash codes.
crank for 5 seconds while in flash code mode
see emmisions page for how.

flash code 11 drops the ASD ! (cam or crank sensor dead)
code 54 cam signal dead?
code 43, spark bad.

Hello I just bought a 92 accord Lx 5 speed. first i found out my fuel gauge gives me wrong reading it says is 1/4 full when is empty. my second problem is when I'm around 1/4 tank full the car shuts off...


I dont know why car shuts off when the tank is 1/4 full. Try replacing fuel filter first then maybe fuel pump. I think you probably have a stuck fuel sending unit. Here is a video of the location of the fuel sending unit.

Here is a video of how to replace fuel pump.

Cut off electric


Your truck has an Inertia safety switch which disconnects power to the fuel pump. The switch has a reset button and can be located behind the floor kickpanels, under the glovebox, or somewhere even under the drivers seat.

It is a part that Engineers can not seem to agree on its location from body style and year.

You should have a fuel pump Relay which can shut down a fuel pump.

Please rate my info.

1990 f 700 fuel shut off relay


There is a fuel pump cutoff switch but no such thing as a relay, but it only cuts off when you have an accident that exceeds 3 times the force of gravity which is like a 5-7 MPH head on..

Hey,i have a 1990 4.0l xj,my fuel pump does not shut off after 4 hrs or so it burns out,any suggestions?


Sounds like a bad fuel pump relay, the relay sounds like it is stuck on.

This is listed as a 1990 4.0 xj, but what model, is this a jeep or a jaguar?

In either case check the relay, remove it and see if pump stops. i will see if i can list the location of the relay on both cars............... Okay the jaguar 1990 did not come with a 4.0 so i will assume its a jeep we are talking about, the fuelpump relay is located on the right fender well on the relay block, here is a diagram of it and relay lay out. hope this is the correct vehicle . let me know if this is correct. good day.

Where is the reset button for the emergency shut off valve for the gas line


RESETTING THE FUEL PUMP SHUT-OFF SWITCH
After a collision, if the engine cranks but does not start, the fuel pump shut-off switch may have been activated. The shut-off switch is a device intended to stop the electric fuel pump when your vehicle has been involved in a substantial jolt.

If your vehicle is a sedan, the fuel pump shut-off switch is located on the right side of the trunk behind the trunk liner.

If your vehicle is a wagon, the fuel pump shut-off switch is located behind the service panel on the right side of the cargo area.

Use the following procedure to reset the fuel pump shut-off switch.
1. Turn the ignition to the OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset the fuel pump shut-off switch by pushing in on the reset button.
4. Turn the ignition to the ON position. Pause for a few seconds and return the key to the OFF position.
5. Make a further check for leaks in the fuel system

Jeep cherokee cranks but no start


this is a fuel problem, fuel pump is bad, or fuel filter is clogged up. check to see if fuel pump is working. check fuses and relays if it does not work. to rule out a bad fuse or relay.

Toy turns over but wont run change fuel filter n fuel pump still


The fuel pump should run for a second or two when you first turn the key on, but then shuts down to prevent the engine from flooding if the computer does not get a signal from the crank or cam sensors which the computer uses to trigger the ignition system. So no spark no fuel. Check to see if you have a spark in the ignition system.
