No power to the ECM , no start no spark no fuel pump batt good all fues good

: ECM determines the start signal status by the signals of engine speed and battery voltage. The ECM activates the fuel pump for several seconds after the ignition switch is turned ON to improve engine start ability. If the ECM receives a engine speed signal from the crankshaft position sensor (POS) and camshaft position sensor (PHASE), it knows that the engine is rotating, and causes the pump to operate. If the engine speed signal is not received when the ignition switch is ON, the engine stalls. The ECM stops pump operation and prevents battery discharging, thereby improving safety. The ECM does not directly drive the fuel pump. It controls the ON/OFF fuel pump relay, which in turn controls the fuel pump.


Does the car have spark , crankshaft position sensor

your testing is no good. (no engine told at all)
the ECM ,only injects using this logic.,

1: fuses good
2: ECM good (i bet yes)
3: CKP and CMP senors dead.
4: if the ECM sees spark dead it cuts all fuel to prevent as seen on TV "CRASH AND BURN" and by LAWs on this fact.
5: some cars have Injector buffer modules between ECM and injector rails.(LOOK OR READ THE FSM)
6: fuel pump dead.
7: fuel filters clogged or it and injectors too (they have 10micron screens)
8: have a NOID light? to see if injectors are not fired by ECM?
the injector plugs all have 12vdc on one pin, do they if not fuse blowN, #1 AGAIN.. USING A DMM, METER.

mostly this list works too BELOW.. (noid lamp fails)
fuses
ckp and or CMP sensor dead. The crank and cam must spin !!!!
if CMP is dead and cam does not spin, well that be cam drive dead.

spark dead, if spark is dead ECM detects it dead and fueling is banned,(blocked)by laws. (fire avoided , win)
way3:
if NOID passes on all injectors (as will spark tests)
fuel pressure gone. we measure it. (bad pump, clogs or bad fuel)

if spark is good test fuel test works.
ever do test fuel on any engine using can-o-fuel or instant start fuel in a spray can, seen engine run for 3 seconds and sounds good.?
RTM FIRST? there are sure more causes, list is common, only. and hard logic truths.

ALL THIS IS CART BEFORE HORSE STUFF.!
1- fuses are first blown
2: scan the PCm is next ,after all if PCM detects spark dead it cuts fuel dead in blink if an eye,(as in no crash and burn as seen on TV)
3: if above is not helping (no DTCS) the we,,

we check fuel pressure on the rail, cranking or at idle.
if out of spec we check FPR and the PUMP voltage.

if pump is dead, 0 PSI (bar) we check voltage to the pump actual
12vdc good or 0v bad, below 11volts bad or battery is weak.!

that is how all EFI is tested,not guessing, not discovering pins the PCM that
floats (ever hear of tri-state logic)
the output of a pcm or computer or any logic module can be
1; 0V GROUND DRIVEN STATE
2: 12v or 5vdc drivenstate
3: or floating, as in not used now and floats to save energy.
best is work from a service manual and no guess and the real schematic.

what matters is,
1: NO DTCs for spark dead, (p0300 is weak spark not dead)
2: pump pressure at spec, cranking and at idle of can be sustained.
3: if pressure fails cranked (a 2 man test) and 12vdc is on the 2 pins of pump cranked then the pump /FPR is bad.
if voltage is wrong at the pump we work backwards to the point of failure on those 2 wires, pump feed.
that how this is done, and not taking a bath in fuel tank dropped on a whim.

There are some logical steps need to be taken 1st. Verify if the engine has air, fuel and spark. Fuel can be checked with an inline gauge at the fuel rail. There could be several different things wrong. Bad ECM, fuel pump, injectors, fuel pressure regulator etc. Need to verify spark, this too may have several different problems. Bad ECM again, power/ground circuit faults, coil pack ect.

double check your fuses if not its your fuse it could be you regulator
and take out your plugs and clean them just because

Fuel pump power starts at the ECM/Batt fuse in the underwood fuse block. From there it goes the the fuel pump relay and then to the fuel pump. If you pull the fuel pump relay one pin should have power all the time. This is power from the ECM/BATT fuse. Two of the pins should be grounded. The last pin is power from the ECM. it hold have power for 3-5 seconds hen the key Is turned on and anytime the engine is cranking. Find out what is going on at the relay and then we'll have a better idea of what direction to proceed. Let me know if you have any questions and I'll do my best to answer them.

under hood has fues box black box passenger side under cover tells what fuses are .There are three fues panels on this car 1 driver side on side of dash,2 inside glove box and 3 is out under hood.I would check you fuel relay switch.if its not it then check ecm electronic control module .you can check this with an ohms meter or smell it see if it smells burnt .good luck

Check the 20a mini "ecm B" fues in the under hood fues block. That supplies power to the relay.

Things that you need for the engine to run
1- Fue
2-Air
3-Spark
4-Timing
5-Compression
your error codes will help you determine which to address

That fuse provides power for the fuel pump. Either your fuel pump is blowing the fuse or there is a shorted wire.
