alright here it goes the other night im driving around and right from the start i felt something weird it would start to sputter a little and kept getting worst i come to a red light it sputtered hard and died i start back up after a couple of trys and it just sputtered really hard and died agian and havent got it started since heres a list of what i have tryed

i have a ls boosted in a 98 civic

new plugs (ngk v-power)
new wires
new main relay
switched ecu between obd2/virgin obd1/obd1 with hondata
put my dizzy in my friends car ran fine
took out the whole engine harnes and looked for cuts or broken wires everything was fine
checked all the fuse
im getting fuel
****im gettin spark but weak i thnk
have three ground and ground on the thermostat from the harness all connected



im stumped one thing i havent tryed is checked compression dont i cant think why it would sputter and the things that happened that that has any thing to do with compression

let me know what you think this is killing me i have no clue
thanks in advance

 

i forgot to say i changed the icav too

 

did you ever just try the ignition coil?

 

nevermind, you used a good dizzy.

 

bump

someone has to know whats goin on

 

Measure resistance on the spark plug wires and it has to be less than 25K Ohms. Make sure the spark plugs have the correct gap 0.043" I think it is. Next, take a compression test and see if there are any problems there. Also, check your turbo for problems such as oil and coolant getting to and from the turbo. Make sure the turbo is spinning right and there's no freeplay in the shaft.

 

the spark from the dizzy is weak but i put it in my friends car and it ran mint the plugs are all gaped at 0.043 like you said and the turbo is mint i dont have a compression tester do you really think it could be that becuase why would it sputter and stuff if it was compression

 

ive checked everything twice that i listed this is killing me could it be a head gasket or something internal????

 

The timing belt may have skipped a tooth or two.

 

nope timing is perfect

 

so im assuming you checked your rotor, it spins when you try to turn the car over

 

no i havent checked that but if it worked in my friends car why wouldnt it work in mine

 

yea i just checked it
it spins the end of the rotor has a little bit of burn on it but that must be normal from spark no??

 

You said you are getting fuel. Where are you checking it at?

Are you just listening for the fuel pump to prime? Did you check for pressure at the fuel rail? Are your injectors actually firing?

 

there is presure in the rail and i have rc 550 injectors and stock ls injectors tried both of them

 

the only thing i can think of is the dizzy becuase it has weak spark but i put in a new coil and tested it on my friends car

 

Go back to the basics.

Air, fuel, spark, timing, compression.

If there is one you havent checked, check it.

 

comprssion i havent checked but y could i be getttin weak spark

 

How do you know it is weak?

It doesnt take much spark to get a car to idle. I've seen some nasty, greasy, half melted plugs still put off enough spark to start a car.

 

you said it was burnt? how bad?

 

i guess i lokked at it and it would spark but it seemed slow and not that much i mean your probably right i dont really know what the spark should look like but i was just gues i gotta go grab a compression tester

 

a little bit its brown and itts suppose to be yellow it only the edge were it sparks off to the wires in the cap

 

ok just checked compession 180 across all 4 but i have a little of anifreeze on my plugs?????

 

come on someone i need help there

 

Ok, it's time to check the TP, MAP and IAT sensors for correct resistance/voltages.
