I just installed a 1998 Suzuki Sidekick sport 18 liter engine, wiring and ECU into a 89 Suzuki Samurai. I got the two wires on the CMP crossed, the yellow with a blue stripe and the yellow with a green...


the car in USA has an OBD2 scan port DLC, that missing too?
connect the scan tool
key on, crank for 5seconds, and bingo, all J18s PCMs report
the cause of no starts, DTC errors, why be blind to that? look first.

the PCM cuts fuel if spark feed back fails.
so my guess, is the 1 or more COP ignitors are failing
are all 4 COPS dead. (coil over plug are they 1998 cops)
do not mix years they are different big time,

wiring errors can in fact damage, the PCM outputs
but not the inputs. CKP is input. or CMP

that Cam sensor, has 2 outputs, and crossing them (Green/Blue)
up causes no harm.!
cross the 2 power wires there blows F16.

are you using a real J18 harness or some CLoned one/?

CEL on key on, or is CEL lamp missing?
this lamp is a key lamp with no scan tool
if out, the PCM is dead.
but with scan tool , 1page one shows, CEL active or not, making the lamp useless to scan too owers.

yours is simular to this
cept cops.

Here are the min, things need to get spark , then fuel.
spark is first.
  1. power to PCM good and ground same.
  2. cops wire correctly no early cops allowed
  3. cam sensor both signals perfect.
  4. MAF voltage key on , not wrong, (air flow) but ecu can mimic it dead.(failsafe)
  5. the Cam sigs can not ever be mimiced by PCM,! so...
  6. if cam sigs are good, the PCM fires cops.
its that easy.
if spark read back works. (ignitor is missing in 1998, and was moved to inside each COP. so the read back must be good from each
cop or the PCM cuts injection (by laws, for fire safety etc)

if spark seems good, the PCM injects, but not if TPS is at WOT,
throttle angle. (TPS fibbing)
that is it.

i do have full 1998 PCM drawings if need be, just need a way to send it, I can, if you ask.

Install ignition coils


On what motor?

5.4 V8 ?

They are in plain site,one screw to remove

May have to remove the pcm on firewall to
get #4 out (pass side rear)

You can find out all your questions googling them

I have a 1999 grand vitara and i am only getting spark from #2,#3,#4and 5 coil im not getting any spark from #1and 6. switch the coil pack same thing



old post. but ill try.for others.
no spark , by WHAT MEANS, test spark plug or DTC codes
just a clue here , really helps. no spark tell me not much.


the V6, 2.5L ???? lots of years, and some have radially different
park systems. (2.0L v6 is case in point)
ill answer for 99 GV , USA. No country stated. so.... ham strung.
now i must look up what coil pack yours has, mine has 6 COPS
would be nice if you said COPS or I have 8 coils.
as some have wasted spark with only 3 coils in a brick.
i go to alldata.com, so can you.
i click spark pages.
H25 engine.
has 6 cops. in 1999 here, just like my 04 (igitors are in the COPS)

no spark using a real test new spark plug ,gapped correctly
at 2 coils. 3pin COPs. do not use wrong type COPs. or blow up ECU.
is:
  1. lost 12v to both dead cops
  2. ECU bad. driving both. (or wires to it)
  3. lost ground conn. to those 2 COPS.
  4. Connectors on those 2 are corroded. (3 pins)
  5. The boots on both are full of carbon tracking and are shorted. a very common fail on old COPS. i buy new boots, they are like $15 not $75 to 150 each full cop.

COP means, COIL over PLUG.(spark plug)

my answers only cover USA spec cars....

did you test he cop boots off, cop?????
can be done.
(hands in pocket test or you glow like a June bug or worse)
100,000 volts there, open circuit, not fun to get NAILED.
been so , 100s of times.but not on HEI, only once. never again.

Where is igniter lacated on rav 4 1998


98? what engine?
the ignitor can be in 3 places on all cars.
1: fire wall. connects to 1 coil, or 2 coils(WS) or 4 COPS.
2: ECU
3 :inside the COPS.

the ignitor changes the induction (spark) coil.
and can be in any of 3 places.

i log in to alldata dot com, so can you (a USA example ONLY)
it has 2 (4pin( Igniters)
so obvious has wasted spark.
power pin, ground pin and 2 , pins to ECU.

it says, in the finder, ignition coils 1and2 with ignitor
in coil finder, and service, it states
remove throttle body to access coils

RTM
see coils, ? see wire they go to one place, the ignitor
follow the those wires, see igniters.

Suzuki grand vitara 2002 4cyl no spark.


THE PCM driver the COPS direct.
2.0L engine right> always post engine type. displacement.
the 2005 has no fire wall mounted ignitor, like older suz.
the ECU is direct drive to COPs.
in a real shop we check the input to the COP if its bad , the ecu or the wires from ECU to COP are bad.
there are only 3 parts. here. not counting the spark plug
ECU/PCM , wires. and COP.
only using a scope can you tell if the pulses to the coil are present.
they are fast pulse on the order of 3/1000th of a second.

Just scanned my 1999 300m. It went into safe mode while me wife was driving it home- 2nd gear only. It had a code P1714 and P0700 come up on the scanner. I can't find anything about the P1714.

1. Disconnect the voltage regulator connection at the alternator assembly and start the engine to see if it runs better or not and to see if the same coil-on-plug (COP) unit codes reset.

2. If the engine operation is good unless the voltage regulator connection is plugged in, it suggests a diode failure of the alternator assembly creating electrical noise.

3. If the engine operation is not any different with the voltage regulator connection unplugged, check the COP unit circuits at the PCM for battery voltage with the ignition switch in the run position and the COP's connected. Perform a wiggle test of the circuits and harness to verify that battery voltage to the PCM cannot be interrupted indicating a PCM failure.
COP 1 is controlled by a Light Green/White (LG/WH) wire at pin 1 of the C175e connector.
COP 2 is controlled by a Pink/White (PK/WH) wire at pin 12 of the C175e connector.
COP 3 is controlled by a White/Pink (WH/PK) wire at pin 24 of the C175e connector.
COP 4 is controlled by a Dark Green/Violet (DG/VT) wire at pin 35 of the C175e connector.
COP 5 is controlled by a Light Green/Yellow (LG/YE) wire at pin 36 of the C175e connector.
COP 6 is controlled by a Orange/Yellow (OG/YE) wire at pin 22 of the C175e connector. 1. There have been a lot of problems with the coil circuit wires breaking inside their insulation near the Powertrain Control Module (PCM) connector, usually within 2" of the PCM. Wiggle test the wiring harness, starting from the PCM and working toward the coil. 1. Verify battery power is present and consistent on the Red (RD) wire of multiple Coil-On-Plug (COP) unit connections.

2. If the battery power supply to the COPs is good, disconnect and inspect the C133 engine harness connector at the top of the engine for a possible connection issue. This connector is a grey 16-terminal connector. It may be behind the rear side of the intake plenum. Service the connection as necessary.

3. Disconnect the PCM connection and inspect the COP unit primary circuits and terminals at the C175E connection. Service the connection as necessary.

4. If the circuits and connections all appear to be in good condition, replace the PCM. Replacement of the PCM will require a programming function to be performed using the Ford scan tool for Passive Anti-theft System (PATS) functions and the PCM is an 8 year/80,000 mile (7/70 for CA state emissions) warranty item.
