The back fire could be from the cam sensor going bad. Do a compression test to be sure it's not a valve. The ignition computer can give you a problem too. Read the error codes to see where it steers you to look.

Engine cuts out and then get steerng assist failure


It would be an advisory noise telling you that the power assistance is lost when the engine stops. Run fault codes to find the reason for the engine stoppage and repair the faulty sensors.

No power going to the fuel pump


first check all fuses.
well if the security lamp is on, and the IMMobilizer light glows
it will never run. (by design) (2 seconds max)
so are the lights glowing?
no power going. (when,)
did you read the FSM on the staged events to get engine started.
my wild guess? (sad i have to ask) is it wont start?
1: IMMO not active
2: battery charged volts near 12.6vdc rested.
3: starter cranks fast. and ASD closes
4: ASD relay sees good spark and CKP, and CMP sensors.
5: engine starts, if #4 is good then it sustains running.
if not ASD drops out in 2 seconds. killing INJECTION.
it cuts the fuel pump too.

the PCM will throw a DTC error code (did you scan it cranking ??)
for if the ASD fails to OUTPUT 12v. at step 3.

the PCM closes it, then looks, and if output is bad, it ends this event and logs the failure..

to check the pump , it takes 2 people
one at the key, and one at the pump wires.
or you WILL miss the 2second event.

one way to avoid all that is to hold finger on the ASD relay
and keyon and see if it clicks closed.
if not ., no need to check pump ,its LAST in the chain,
if the ASD clicks and drops out, during that click the pump does run
for 2 seconds, min.,
if the ASD is dead, check the PCM control line to the ASD for
making coil energized in the ASD relay, (12vdc across it for 2seconds)
if the coil is energized, and the DTC throws, for bad ASD , it is.
if the ASD goes, hot only for 2 seconds, again use any $9
scan tool to see the error.
here is the scan too tests. most books forget.
1: scan tool connected.
2; Crank engine for 5 seconds, (min)
3: release key. BINGO, the ECU tells you why the ASD dropped out.
eg: ASD error, CMP error, CKP errors or others (spark?)
does RPM read near 250rpm cranking? on the scan tool?
Is TPS throttle angle near 100% (cutting fuel) ? bad tps. (cut wires)


fixing cars without a $9 scan tool , as sold on feabay is 100x harder.
get the tool and use it.
they rent them cheap or loan them for free.
not to be confused with a code reader, which are near useless.
imo.....

91 toyota v6 is not firing


ok , (killed?)
there are 6 spark plugs, it will take all 6 firing to run
are all 6 sparking, called a spark test.
BTW1, the ECU will not inject fuel if it even suspects spark is bad.
it has 3 monitors for spark, if one dies, fuel is cut and in many case
the fuel pump too, all cars. (fire safety)
so SPARK is first.
  1. check spark? if spark is dead.
  2. then Insert the diagnostic jumper clip (paper clip )
  3. in to the check terminal.
  4. and then crank for 5 seconds.
  5. Got DTC errors (flash codes) for CMP, or CKP dead? or spark dread codes. ? BINGO?
  6. The ECU will tell you most times if spark is bad. and why.
ever do a 60,000 mile tune up in the last decade?
if not , maybe now is that magic moment?
fuel can burn weak or no spark.
the 60k also nets you a new fuel filter .
check spark directly at the the coil too....not just the 6 spark wires.
if the coil sparks and not the 6 that means the cam belt slipped.
(hard to believe a chain can but see 2 like that, owner was deaf)

if you have spark, then test fuel works
spary it in now.
verrrommmmmmmm stall.
?
that means the fuel pressure is low.
if you get this far,the rest is easy, ask.

Turns over but no start


WHAT ENGINE ?????? 4, 5.2 or 5.9 Liters?
Fuses are First, always for ever. on electrics or EFI.
dry rail cranking ! you must crank it.
(if you have liking injector or leaking regulator it can drop fast ,so crank on) yes, 2 men or 1 and small boy, LOL
so check voltage at the pump cranking. please stop guessing.!

the ECU commands up the PUMP , cranking or running
so crank and read voltages at pump or at FP relay.

pump activating, is by premissives. not just a key on event
due to crash and burn rules. (unlike on TV)
same with injection. (spark must be good)
first , buy your self a voltmeter (DMM/DVM) its a very easy tool to use
and on volts, mode, totally harmless to you or car. !!!

be aware, that on some cars
if there is no spark, there is no fuel pumping
or it might take a second to detect no spark and the pump is cut
or on one of my cars the pump works the engine starts for 1second
and the ECU sees no spark (dead tachometer ) even though spark is
good the ECU sees no spark and ALL fuel is cut, injectors and fuel pump relay ( you never monitored the action of the relay?. and its dead.? i bet?) spark monitoring can fail with good spark, !!!
the path, on all cars.............. pins and colors change to confuse...
-------------------------------------------------------------------------
the FUEL pump relay is in the PDC
it has 4 pins, its just a 4 pin std, relay.
a coil and a contactor
if the coil is not HOT (12v across the coil) cranking
there will never ever be pump action.
so the first test is to check the PUMP relay coil wires.
the coil hot side is 12vdc key on
the other wire, marked. C20 DB (dark blue?)
it is 12v keyon
and when you crank the PCM grounds this wire and it must go
to 0v, (0.5v max) if not the PCM is in CUT FUEL MODE.
99.999999% sure, its not a bad PCM. see?
if this line dont go low you must find out why the PCM is in cut fuel.
this is pretty easy,its called a scan tool. got one
they only cost $9 (ask)
if the coil is hot at C18 relay pin and 0v at C20
this state the Relay is energized.
so we check pins C16 and 17,of said relay
we check C16 first. its 12v even key off, hot at all times if not, the fuse is blown. (or battery totally dead)
then crank and pin C17 goes hot(note my order of testing, its not random) C17 dead, is bad relay, C17 12v, cranking is dead pump.

C17 is DG/wht wire, (darkgreen.with white stripe?)
if this wire is cut the pump is dead
so is the pump dead, if hot this wire is, and the pump ground wire is cut.
when i say cut that means cut or corrosion,etc.
eg; gross resistance in the path.

takes 4min to show, and longer to type this...
the G305 pump ground black must not be bad. (12v on black wire is just that while cranking)

i will not fully cover PCM permissive on the pump.
but will do so in short.
1: ECU sees spark loss, for any reason.. even when good real.
All ECu do this differently. many read the spark coil primary
wires of inductive (EMF) kickback , on one or all coils.
other cars its just the tachometer signal dead.
2: CMP errors (cam sensor)
3: CKP errors. (crank sensor)
4: TPS stuck at WOT , usually only cuts injectors.. (unflood mode)


ive built and programmed PCMs from scratch and am aware of all pitfalls here. am.
if have the drawings, ask.
or log in to Alldata.com

again, connect the $9 scan tool
keyon
crank for 5 seconds. (min) max 15)
does RPM roll from 0 to near 300? no? bingo.
does DTC 340 or 350 store as you crank or release key
and do not turn off key, wait 1 second, see if DTCs are stored
in the PCM looking with any scan tool made..
if yes, BINGO !!!!

I have a 1992 Honda civic lx with a 1.5 four cylinder, and Ive replaced the ignition switch the fuel pump relay and the fueled pump itself however, the fuel pump still doesn't prime when I turn the key...


no start , crank perfectly
so , got spark?
the ECU has programming (ROM) and in fact kills all fueling with no spark , (even if it thinks there is no spark, even if spark is ok)
all ECU use a way to read back spark quality, (ALL){LAWS}
how honda does it in code, i don't know , see C R O M E forum)
turn the key over means nothing to me.?? sorry, it doent/
try saying what postion? cranking? or just keyon.
now some more EFI rules.
The EFI (some) do not activate the pump relay until cranking.
some do just key on for 3 seconds, read the FSM, its free.
need a link to the free manual? read the ECU logic on that.?
and prime has a special meaning, it means purge air,
its not for fuel. some system send a fast prime pulse. to clear air from the pressure lines, this plus does not inject.
that is how EFI works,

the flow
1: key on, ECU sends prime pulse, (air purge)
2: some ecu, run pump for 3 seconds, and pressure hits 35psi? RTM.
3: all ecu activate pump cranking and running.
4: now check pressure. !" 36 psi FSM stated spec"
5: now crank, if the ECU sees no spark errors, it injects
6: if the ECU sees WOT. it stops injection to clear a flood, cranking.
those rules cover most ECU made.

honda this year has a special feature called,
Fuel Cut-Off Control'
if this messes up, it i can cut fuel
does this help?
even better is this site, (has all the facts..)

The steering is getting hard


Check the liquid level in servo tank. If it's low than fill it up to max. Than after couple days if the liquid is lower than before, that means that it leaks somewhere, maybe on the pump or on stearing rods...

Cuts out while driving with plenty of gas


possible fuel pump or filter, if the timing belt goes the car stops completely and will not start.


The fast indicator flash is odd and usually means a blown bulb, perhaps a bad eath cable from the battery
