What means in car engine Ecc o Ecb - 1997 Dodge Neon

no car told
make ,model ,year
most ecc??ECU/ECM?/PCM replaced are good
bad inputs top cause.

ecc, engine control controller?
no car no answers possible ever asking the blind

motor swap>?

Problem with 1993 Toyota Supra I have isuzu elf fire engine local mentinence department cut down the ecc box timer that's why i need electric diagram.

my lexus 450 hybrid system said check and the engine won't start
what shuold i do

A few things to check:

Wrong spark plugs installed - causing too many misfires
Timing problem - the ECC (Engine Control Computer) will give up after a short while if it cannot get the engine to operate in correct time
clogged fuel filter
clogged air filter
clogged fuel strainer
worn distributor cap/rotor
failing fuel pump
vacuum leak
faulty ECC (Engine Control Computer)
ignition coil failing - the ECC will stall the engine if too many misfires are detected.
wireset - faulty spark plug wire(s) causing too many misfires.
faulty fuel pressure regulator
EGR valve faulty

If the engine is misfiring alot, it will **** the resulting unburned fuel out the exhaust pipe, so check for this as well.

For the sake of completeness, here's the full no-start Troubleshooting Guide for the 2001 6 cylinder 3.5L MFI Mitsu Diamante, but the problem with your car is line item #6 - the ECC (Engine Control Computer) is shorted/dead. Without an ECC, the Diamante will (a) get no spark, since the ignition timing comes from the computer, and (b) get no fuel, since the fuel injectors are operated by the computer as well. The engine will turn over, since running the starter motor is a non-computer controlled matter of a correctly functioning ignition switch, a charged battery, and good wiring to a functional starter motor/solenoid, but will never start.
The clue pointing directly to the ECC failure is the blowing ECC fuses. These fuses are blowing to tell you that the ECC is shorted dead.
Since the ECC is expensive, exhaustively check out all other possible sources of the problems, but with so few problems causing loww of both spark and fuel, combined with the blown ECC fuses pointing directly to the ECC, it seems that the ECC is the only culprit.
Here's a used 2001 Mitsu Diamante ECC at Ebay for $175.

The fuel pump strainer is a sock-like strainer in the fuel tank on the input side of the fuel pump designed to protect the fuel pump by straining out any debris in the tank (similar to the way that the fuel filter protects the engine/fuel injectors/fuel pressure regulator).

Your ECC has no memory cards that have to be transfer to the other ECC, the ECC is a seal unit, just install, no reprogramming needs to be done, ECC is under hood, passenger side, rear engine area, above passenger side blower motor, mounted on fire wall.

The only thing that it would most likely be (if not the ignition module, the fuel pump, a faulty fuel pump relay if applicable, or a faulty ignition coil pack but only if one coil pack is used, and if more than one coil pack they would all have to be faulty to shut down the engine) is the ECM/ECC, especially since the vehicle shuts down about every 10 minutes, and that is the classical sign of over-heating electronics that act almost normal until the electrical componet becomes too hot and then begins to malfunction.

The ECM (Engine Control Module) or ECC (Engine Control Computer) for those vehicles were not manufactured very well and were prone to failure, and that is why you can purchase a re-manufactured one for only $85.00-$89.00, and the re-manufactured one will not have the stock defects.

If you do purchase an ECM/ECC and if it has a PROM chip (Programable Removable On-board Memory) that must be installed from your old ECM/ECC be very careful when removing and installing the PROM, and the plastic retainers on either end of the PROM will push back away from the PROM and lift the PROM out of the connector on the circuit board. When installing the PROM be sure that the retainers are pushed back and that when the PROM is pushed down into the connector that the retainers lock in the PROM. Not all vehicles will have a PROM and be very careful with the PROM if you do have one to remove and install because it can easily be damaged, and if it is a necessary procedure to change the PROM, then the ECM/ECC that you purchased should come with a detailed diagram and procedure for you to follow so that the PROM is properly installed into the ECM/ECC.

Here are two links that show the price of the ECM/ECC from a major auto part store depending on if the vehicle has a 2.5 liter 4 cylinder engine, or a 3.3 liter V-6 engine.

ecc and fuel pump relays good? when the engine is turning over, does the ck engine light go out? if not the PCM isnt getting a crank sensor signal. Power and grounds all ok at pcm?

Are you sure that you don't mean the cooling fan control module? It should be located up front next to the cooling fan. It is square shaped and has a long square shaped plug going into it. Reads the temperature of the coolant and passes the information to the engine control computer (ECC). The ECC receives analog information and signals the cooling fan switch to cycle the cooling fan on or off, as required.

YES I FIXED IT IT WAS THE THE POWER STAGE UNIT THIS ECC SYSTEM HAS 20 PAGESOF ALL KINDS OF VOLTAGE TESTS AND YOU MUST HAVE KNOWLEDGE OF THE COMPLETE SYSTEM AND WHAT TIS POWER STAGE UNIT DOES IS NOT LET THE ECC RELAYS GET TOO HOT AND SYSTEM SHUTS DOWN AND YOU MUST RUN ALL KINDS OF VOLTAGE TESTS TO PROPERLY FIX THE CLIMATE CONTROL SYSTEM AND HAVE ALL I MEAN ALL THE DIAGNOSTIC DATA ON THIS SYSTEM
