Engine turns over but wont start, no spark to plugs
#5
ok,
vsv no each vsv has that power wire, its just a daisy chained power wire. blue black.

Paired with the white/green wire (red plug) ive no clue where this is, a white wire?
or the green/yellow wire (blue plug)? look above see it? the EGR VSV?
there are 3 vsv.
EGR, EVAP, and Dashpot. each is wired just like the drawing above.


dizzy wires:
the white wire is CMP out of the dizzy, and should never ever be 10v only 0v or 5v, it make a square wave as you crank (or run) 0v 5v 0v 5v repeats. to get 5vdc there is a very bad sign, or the ECU has lost its ground or power to the ecu.
black is ground. 0v

where to head, you are in the wrong place now. the dizzy is and input to the ECU. and that is not first things.
the ECU is first. and first is POWER it IT.
like a said , pins B1 and B7 are #1
if it has 12vdc power then the next to read is
the 5v pin.
that is most easy to read at the TPS pin, Gray-red wire, it must be near 5v, 4.75 to 5.25V

ah green plug, yes the ECU green plug. that is the power side
the yellow plug (white new) is the signals pins,.
memory wire is hot. ok so fuse to that is good. white.
pink there is no pink wire, so must be faded, B8 red?

Blue is WRONG. dead wrong.
solid blue means you are seeing IG coil power, feed through the main relay this means the ECU is blown or the ECU is no longer grounded
all the A pins are dead, because the ECU is dead
the ECU is dead because MAIN is dead.
can i assume this is a usa car, and not European with an immobilizer, ? surely there are no GEO's with this on or continent.

on our ECU the 56b30 its just a diode to ground on B15. blue
the only way to blow up that diode inside , (seen it) is by hot wiring the fuel pump relay and landing on B15 blue by accened and boom the diode explodes.
b15 at 12v.
there is only one other possible way , that is the ECU lost its ground. at B2 and B10

g105 ground wire on dizzy bolt missing or loose?
G106 thermostat housing ground lug missing,fell off or loose?
G107 lug on wiper cover bolt? missing, loose?
keyon
all i need now is the voltage on B2 (black-green at green ecu socket)
then at B10 black-blue (same green conn) both are 0v ECU power ground points. critical.



the ECU pin out is here.

do not get confused by suzuki calling GREEN B and Geo calling it A. (GM GEO sillyness that)
the big pins are on the green connector. power. and ground.
so b15 is geo B15

we only need to find out why MAIN is dead.
it must be closed, anytime the key is on. must.
if not ALL is dead.

here is the white ecu connector and all voltages, all yours will be dead until main relay starts working.
