RE: Engine turns over but wont start, no spark to plugs - robbybobby - 10-31-2014
On another note, pulled instrument panel to see about CEL. No lamp in that socket but had a piece of tape over it (thanks PO).... Replaced with another bulb and got my CEL. Put the jumper in and got a code 42... Don't know if this helps or not at this point...

42 is a crank angle sensor on my vehicle. You may want to put your vehicle info in your signature so that folks can help you better.
RE: Engine turns over but wont start, no spark to plugs - fixkick - 11-06-2014
42 is clear as day, all the time the ECU wanted to tell you what was dead, how about that.!
i means 1 in 10 pulses from the CMP are missing, or ALL OF THEM. (dead)
nice PO, not.
so, make sure the grounds are not bad at the xxxxx oops no year or engine stated
use a signature or profile to tell helpers what you have.
all this is easy stuff.
on the 8v those ground wires on the DIZZY mount are not for fun, they are key in the ECU ground systems
and the dizzy almost never fails the CMP, unless the grounds are bad or the side connector is loose or corroded.
92 8v.
i read the whole post its and 8v. with only 1 injector
so read my bad grounds.
here.
G105 ground? bad?

read my CMP test , on my no spark page, (i really have no spark it says) then.
the cmp can be tested 3 ways, (scope, meter and LED lamp)
http://www.fixkick.com/IGN_timing/no-spark.html#ECU_LIVE_DIAGNOSTIC_TRICK_:_89-95
the best meter to uses is a 10 buck walfart analog needle meter. and one leather sewing needle for back probing on car.
most easy and no making tools, or $100 boat anchor scopes.
the FSM covers that why, fully (meter set to 20vdc, and test lead black to ground and white dizzy wire backprobed (do not unconnect the dizzy or it will be dead)
but here is a video with a LED (dizzy out of car)
a 12vdc battery
and LED.

and see it flash.
http://www.fixkick.com/videos/FLV-all/showtime.html#CMP
or connect the voltmeter to the white pin, on the Dizzy connnector, back probed with sewing needle.
and see the needle (meter needle) wag 0v ,5v, 0v, as you crank engine.

Sorry for the delay. I have been gone out of town for work for a while and haven't had internet access.
First off, I want to say thank you for all your help and suggestions on figuring out my issue at hand. Second, I have to say I feel like a dummy (more so, I am just unfamiliar with what I am working on).
I determined the issue on the tracker after staring at the engine compartment and the wiring diagram for a bit. Turns out, there must have been a slice connector where the fire started (probably the culprit), which connected all the blue/black wires together (under the intake manifold, so hard to see/tell). So after staring at the diagram, I decided to connect all 4 blue/black wires with a wire nut to see what happened... Did so, turned car over and it immediately cranked up and ran smooth!!! All I could do was sit back and laugh because it was so simple of a mistake, or not knowing what I was dealing with. Anyhow, I connected things with waterproof connectors and wrapped all wires tightly. Been driving her ever since with no problems!!!
Again, thank you for all the help and support!

Fabulous.
yes, those under the intake are very hard to examine.
great that she runs again.
happy trails !

If only it was so easy. Getting ready to tackle mine again after a few months of see it sit in my drive untouched.
Congratulations!

no spark, top cause on any 1.6l G16A or B.
is cam belt bad. , snapped, slipped or shredded.
after 60k miles it does that and the CMP goes dead, not spinning or the ECU seeing the CMP acting so odd it cuts spark dead
RE: Engine turns over but wont start, no spark to plugs - fixkick - 07-02-2024
there are other causes besides cam belt drop ( spark dead at the actual spark coil itself)
CMP dead
spark coil dead,
igniter module bad.
the Noise supressor module fell off the harness conn and the ECU sees that as dead tachometer signal and cuts spark dead.
one more oddity , if car has the cruise control and the CC model shorts the tacho wire, spark ends, easy fix unplug CC module under dash
one more oddity, the speedo cluster tachometer modules inside can short out (bad caps) and kills spark dead. (easy fix pull cluster connectors off it and spark recovers.
all this and fuses and any wires seen here related.

lots of view here so , I add these comments to folks with dead spark.
