Customer:

good question haven't checked but it was running fine before booster change

Customer:

did take off cover and poured some gas in carbeurator and no difference stil turned over but nothing

auto :

ok i understand either the engine will have no spark or no fuel one is causing this issue

auto :

ok so u tried a alternative fuel source down the tbody

Customer:

what and how do you want me to check first?

Customer:

yes

auto :

ok so most likely u have no spark,have u checked the fuses in the underhood fuse panel

Customer:

yes which ones in particular I could check again

auto :

ok let me ask u this first u say u have a carburetor is that correct or do u have fuel injection?

Customer:

carburetor

auto :

ok is this the original engine?

auto :

because this engine should be fuel injected

Customer:

yes

auto :

ok i want u to check the ignition fuse, but check them all

auto :

let me know ill wait

Customer:

ok am doing that now

auto :

ok

auto :

also check the ecmb and ecm1 fuses

Customer:

nothing yet

auto :

ok did u check the ecm b fuse and ecm 1 fuse

Customer:

checked all the fuses saw a ecm 1 but not a ecm b?

Customer:

checked both fuse box under hood and on dash panel

auto :

and all were good

Customer:

yes

auto :

ok now

Customer:

not sure about the square larger fuses?

auto :







1. Access the ignition module above the right hand rocker cover.

2. The Pink (439) should have key on B+ at terminal A.

3. Black/White should be a good ground.


auto :

do u have a voltmeter

auto :

or testlight

Customer:

i have a multimeter

auto :

ok great

Customer:

i know this might seem elementry but what settings do i need to put it on to check the fuse

auto :

dc volt

auto :

it all depends on what meter u have does it say dc volt ?

Customer:

Ignition module is mounted where?

Customer:

also have a simple test light My son has the multimeter that he got for xmas but not sure hopw to set it.

auto :

if u are sitting in the vehicle it is above the right valve cover

Customer:

first thing is where is the ignition module?

auto :

the ign module is mounted above the right valve cover of the engine

auto :

if u are sitting in the vehicle if u are looking from the front its the left valve cover

auto :

do u need a diagram?

Customer:

that would be helpful

auto :

ok thats fine give me a min

Customer:

so if i am looking at the engine from outside the car its on the right? next to the driver side front tire?

auto :

no if u are looking from outside the vehicle its on the left side passenger side above valve cover

Customer:

ign module has like a spark plug wire coming in top and then a three wire connector?

auto :

do u see a image

auto :

yes the coil is on the same bracket as the ignition coil

auto :

the wire is connected to the ign coil goes to ignition cap

Customer:

what do you want me to check?

auto :

2. The Pink wire should have key on B+ at terminal A. with key in the on position

3. Black/White should be a good ground.



9:16 PM

Customer:

trying to follow. but don't quite understand. "the pink wire should have key on B+ at terminal A."

Customer:

termial "A" is what is shown in the diagram?

auto :

ok ill try and explain better the pink wire on the ignition module should have power with the key in the on position the black/white wire should be good ground

auto :

u can use the testlight for this test,,,,the terminal a is the pink wire on the ignition control module wire connector

auto :

the diagram shows u all the electrical components under the hood i was trying to help u find the module with this diagram

Customer:

have power to pink wire

auto :

ok do u have ground on the black/white wire

Customer:

tested the pink wire with the black/white wire and beep

auto :

ok so we know the module is getting power and ground,

auto :

do u have a spare spark plug around

Customer:

no i do not have a spare laying around

Customer:

nvm found one

auto :

ok i want u to remove the coil wire at the distributor install your plug into the end of the wire,crank the engine and see if the spark plug has spark

Customer:

ok

Customer:

houston we have a problem

Customer:

no fire

auto :

lol lol ok u have either a bad ignition control module or a bad coil

Customer:

do you have a diagram of the location of those?

auto :

they are on the same bracket u just tested power and ground at the module

Customer:

is there a way to test which one it is?

auto :

the wire u took off the distributor cap was it the center one

Customer:

i just took the wire off the spark plug and put the spare plug on it

auto :

ok no u cant do that u need to test for spark at the distributor coil wire,

Customer:

so i need to unplug the wire from the distributor cap and put the spare plug there then test for fire?

auto :

yes the wire u take off the cap is the center wire it goes from the coil to the cap (center wire) on cap

Customer:

well there are 4 wires on each side of the distributor cap

auto :

ok its that style cap remove the wire that goes from coil to cap at cap then check

Customer:

you were talking about the wire right next to the coil

Customer:

just tested that and there was fire to that

auto :

ok so u have fire from the coil?

Customer:

yes

Customer:

i had unpluged the wire from the spark plug and plugged another sparkplug in that wire. but that was not what you were asking me to test.

auto :

ok let me ask u this do u have spark to the spark plugs or just off the coil wire

auto :

do u have spark at the engine spark plugs or the plug u put into the coil wire?

Customer:

yes

Customer:

just tested that

auto :

yes what

Customer:

i have a spark at the coil wire like you asked me to test

Customer:

then i tested the spark at the engine plug and i have a spark there too

auto :

ok is the spark at the coil wire the same as at the plugs nice blue color spark

Customer:

it was much stronger at the coil

auto :

ok your problem is week spark u need a distributor cap and rotor

auto :

if u remove the cap im sure u will find corrosion under cap

Customer:

ok so should i check for corrosion first

auto :

yes but if it is corroded replace it they are cheap

Customer:

ok im going to check that

Customer:

while im checking that (on a side note do you have a diagram or know the location of the windsheild washer pump for a 2006 eclipse GT)

auto :

yes it is in the windshield washer tank mounted on the bottom u may have to remove the plastic inner fender to get to it.

Customer:

yes there was some corrosion in it

Customer:

but i have no way of getting the part tonight is there any way we can follow up tomorrow?

auto :

change it with a new one and get a rotor to im sure thats the problem

auto :

a33 is the wire connector to the washer pump...

auto :

make sure u print these diagrams they will be usefull down the road

Customer:

the rotor is corroded too

auto :

yeah i figured that

Customer:

i guess it was just coincidence

auto :

yes they fail all the time i probably see 1 a week at the shop

auto :

do u have any more questions for me?

Customer:
