SOURCE: Battery light stay on

Sounds like you covered all the bases, which is good. I would now start looking at fuses and wires. Start at the battery. Other than the battery cables, look at the wires, look for anything loose, especially at connectors, wires that have worn or cut insulation, or wires that look burnt or are unusually soft. Check the connector and the wires coming out of the alternator too. Good luck.

SOURCE: The car starts and after 20 mins of running it

check all wires and grounds, there mabe a bad wire in the system. check alternater wiring also. if all else fails check the ecu.

Hi I have a 1995 C200 Auto Sedan chs WDB 2020202F241703, I think I have a problem in the ECU. Only runs on two cylinders, I have changed the core pack on the 1 & 4 cylinders but the problem persists. The other problem is I don't know where the ECU (engine computer ?) is can anyone help ?

SOURCE: car dont idealing probably, when the engine is cold it barely will start but when the car is warm it works fine

Try resetting or clearing the error codes, the process for this, applicable to your vehicle will be sitting in a forum somewhere. If a problem still exists, a new or the same error code will appear. Goodluck searching! :)

SOURCE: need location of ecm/ecu on 88-93 buick regal

my name is David ,I live in Austin Texas and do alot of mecchanic / technician work around town. I do have my certifications and have work at dealerships and Autozone as well...with all that being said... if you are not getting spark on this vehicleand it is not likely the coils or the module. The crank position sensor the device responsible for reading the angle ( timing ) of the crankshaft. The crankshaft has notches in it that pass either through or near the crank position sensors magnetic tip. The ignition module then interprets the signal and allows signal ( electrical current) to pass into module and on to ignition coils...then on to spark plugs via spark plug wires/cables. The crank position sensor is located on the back side of the engine in the gap between the engine and transmission housing. it is held in place by one 8mm (metric size) or 5/16 standard size bolt. Use a wrench though unless you have small hands or a 1/4 drive socket set. 9.99 times out of ten it will start if there are no other issues... your welcome

1992 isuzu rodeo has no spark I have changed the coil , the rotor , the spark control modual , the ecm , the pick up coil , still no spark could it be the ecm relay ??


double posted, why?
I guess you are h3ll bent on gue$$ and not testing.
so keep going replace everything, we love to watch.
why not use the diagnostic jumper as posted in your other posting.
why>?
no spark out of coil right.
recap of last answers.
fuses, good, all 7 for ecu +spark good????????
we test them not guess, but ones that look blown are.
CEL Glow key on,?
flash codes ok 5 seconds cranked.
CKP good , the ECU will tell you its bad with flash codes.
why skip this key test??????????????????????????

The ECU must have power ! this is first. not changing out tons of stuff, 12vdc power,, and there are 7 fuses.
i bet you never tested them
or measure all ecu power pins to see if its has power first.
and is FIRST, no brain,(ecu)no spark and then no fueling.
if the CKP is dead, there can be nos spark.
ever.
I can only presume you connected a good new spark plug
to the actual coil tower point, then ground the spark shell.
and cranked and spark really is dead, 100 years, same way.
if dead, check 7 fuses.... seen in the book on car.
log in to mitchells diy. (google that)
and read how it works, its all there, read it.
a schematic to.

Opel corsa baklie 1.6 sport 2007di engine light dont com on and dont haf sperk


the signal from the crank angle sensor thats mounted against the block pointing to the crank pulley is what tells the ecu that the engine is turning and to provide spark and injector pulse
so your possible problem area is the ecu
also check the ecu harness plug wires and pins
make sure the crank angle sensor is plugged in

How do I fix a crank no start issue with my tacoma? It cranks but won't spark and I have replaced all 4 coils and spark plugs as well as the cam and crankshaft position sensor and it starts when it's warm...


this is easy, 'an ECU pro, (custom) retired.
uSA car, assume1
has OBD2 PCM, see above.
the first error is not checking spark at every spark plug,
no engine stated but its I4, sure.
it has 4 cops with DIS igntion system great hint there.!!!!

if one cop dead, one cop bad
if all 4 dead, the PCM has CMP/CKP errors (sensors)
so you failed to spend cash on a real scan tool, not 4 useless cops.
then youd done this, (posted 100 times, )
  1. check all fuses first with voltmeter (sans fsm schematic, sad to do all)
  2. keyon, CEL lamp most glow ! if not fuses blown.
  3. connect OBD2 scan tool, if comm fail no, the fuse on pin 16 of DLC is blown , fix fuse, yes, scan tool now works ! talks.
  4. i crank for 5 seconds,
  5. i release key, not off, BINGO DTCS for sensors dead,
  6. works on all cars 1987 to now,, all ecus will tell you this. just LOOK in fact they all report 1 pulse in 10 missing, (FSM words)
scan tools work
they can be barrow, bought, rented, )
A DEAD car needs a tool that is if you dont wont to go broke guessing what input to ecu is dead,(CKP./CMP)

fails cold, so my guess is you missed one sensor

now wild guess2, sure im blind and blind messup 90%
say all cop coils do spark , testing errors.
say you check spark timing on #1
its way off,
the cam has slipped, i can say what, no engine stated
and compression is 1/2 normal, that be first on older cars,
if sparks good, and compresion good, try test fuel cold
run now?

if spark is good and timing good, use wide open throttle to clear
flooding on all cars.
it cuts fuel.
if id dont clean spark must be bad,
takes spark on all 4 not just one, so.... not stated.
you need to do tests, and stop guessing at parts
if you put in just 1 bad part, now you have horrid,double failure.

for sure, do that tests and STOP guessing.and win.

How to check a ignition coil pack to see if its good,


the coil does not crank the engine , the starter does that, sorry.
(if you ever had to hand or foot crank and engine , youd under stand that. (like motor cycles or boat engines, or per 30s cars.)

in fact will crank all day with no spark parts on car..

x2, the scan tool does tell you why there is NO STARTS, CRANKS OK. The pcm can detect, one missfire in 10 cmp;ckp signals.
  • CRANK FOR 5 SECONDS
  • release, key
  • scan tool has DTC errors?, read the believe them.
no engine stated of 4 or more,

U checked everything but spark,
why, check spark at all cylinders, all most fire or the engine will not run or stall.
That test be first, if not starting (AFTER SCAN TEST)

IF NO spark fuses are next , not last.
lets do no start fails tests. (cranks perfectly 200 to 300 rpm)
  1. : check fuses
  2. key on, CEL lamp must glow, if not , ECU fuse blown.
  3. crank with scan tool , see P03xx DTC errors, see RPM dead.?
  4. check for spark? got spark x4 or times number of cylinders?
  5. got spark try test fuel now, runs for 3 seconds?
  6. yes, runs on test fuel now means lost fueling
  7. no, dont run on test fuel, means, 1 to 5 done wrong above or engine compression bad.
  8. bad fueling, huge number of tests. check fuel pressure now.
confused, try a shop and watch them, learn.

INJECTORS ARE NOT WORKING


wow no year, are you kidding? and worse no car body. wow. x2.
what does not working mean, they dont squirt
or they lack 12vdc on one side and the NOID signals on other are dead.
all dead means. (no squirts)
1: blown fuse.
2: main relay dead.
3: the ECU wants them dead.
4: fuel pump dead or ECU wants it dead.

what does want mean.
want means. the ECU logic, halts injection for these reasons.
A: lost spark.
b: lost CMP or CKP sensors, which kills spark
c: cranking wide open throttle ,cancel injections for magic secret unflood mode.

so , why did you start (if you did) at injectors, they are last to work.
all the above most work for or the ECU cuts fuel.
the ecu cuts fuel to prevent CRASH and BURN, as seen on TV.

so you check spark and you got what?
good, ? one dead , all dead?
if spark is all dead, scan the PCM.
does it show, P0340/355 DTC errors, for dead cmp, or ckp>
that be first , top of list after fuse checks.


tell car , year, and all symptoms, ?car will not start and spark is ////???????????

Ok guys I have a 97 lhs the fuel pump went bad replaced it car ran great again but now it wont start turns over have replaced the fuel filter and the coil pack and still it wont start im stumped please...


this is not unique to chrysler, at all, its EFI.
all EFI works alike , the shapes change to fool the non tech.

i dont know about you, but in my shop
i check fuel pressure and you found it at zero
then put in a new pump and didnt check pressure.
why would you do that? after all it was zero.
and you do that and its still zero. then find a bad wire /connector
in the fuel pump power feed or the fuel pump relay.
or ? a inertial cut out sw, or rollover switch. (i said generic)
now rule 2: if spark is bad, the ECU cuts fuel,
BY DESIGN. that dont mean spark really is bad, but does mean
the ECU can not SEE spark, or that the Tachmeter line is dead.
All ECU monitor spark 1 way or the other, and if that fails.
there WILL BE NO INJECTION period.
use your scan too to see DTCs while cranking and dead RPM cranking for 5 seconds, release key and look for crank or cam
sensors errors, key key on for 1min to see them pop up.

your are stumped because you are not troubleshooting, only guessing. and will make you broke fast.
here at the simple tests, in the proper order.
1: compression on all cylinders. if all are horrid.
the cam timing is way off. no motor will run like this.
2: spark check for spark. ! at all spark plugs, not just one.
3: make sure the ECU is happy about spark, RPM moves cranking , etc.
if spark tips are dry at this moment test fuel can be used.
does it start now then stall as the the test fuel is consumed.?
4: check for injection.
do the injectors click , do all of then click , cranking>?
if all fail, i can assure you the ECU is CUTTING FUEL!!!
if one dont click , then run a NOID lamp test in this injector
and make sure the coil reads near 10 ohms not infinity.
5b: you can do an injector balance test.
cranking, see that the pressure drops, as you crank.
Ill not cover this , as its a SOP proc, in all EFI books published.
but take to bank, can witness the drop in pressure and know the injector does in fact inject.
that way or by looking at fuel soaked spark tips.

the injectors can fail in many a way, they are fuel cooled.
A:shorted coil, open coil
B: ecu driver dead.
C: injector clogged or leaking (leaking causes flooding)
the injector has inside 10 micron screens. tiny,
d: bad fuel. cant burn or clog s screens.

you are now totally confused (above) or are un-stumped.

if you dont understand EFI at all , then lets go back to 1920.
this works too, on all otto cycle engines
1: compression, good, time number of cyclinders.
at spec. all equal, most 150psi to 200 is typical today.
2: got spark times all cycliners.(oh, yes, timing right)
3: over fueling or under.?

that is it, its and air pump , if it can pump air, it's hopeless.

the 3 steps work , every time. the tests are easy and are documented for 90 years, now.

Hyundai Exell will run for 20 min's and will die


hi there, is it carby or fuel injected?

CARBY - fuel pump, dies when warms up (most likely if you still have spark)-to test for spark remove a lead and stick a small screwdriver in and sit a few mm from an earth point(dont touch the metal part of the screwdriver) turn the car over you should see spark.
- needle and seat
- fuel filter (not likely)
- coil (if no spark when test)


FUEL INJECTION - i would go straight to the ecu, the 1990 is renound for having a **** ecu, they blow capacitors real easy and carry on in wierd and wonderfull ways. hope i helped.
