no spark

[Kevspec]

ok this has me foooked my car has been running perfect no issues at all didnt change a thing then i went to start and was a pig to get going and running on only a few cylinders.

ive tried few different modules that i know work tried few different coils i know work and also bought a new dizzy and still wont run.


im lost dont know what else would cause this

[Kevspec]

only other thing i can think is the ecu has fried

Are you sure it's not spark but something like a bad fuel pump?

[Kevspec]

new fuel pump new injectors and its pumping plenty of fuel into the engine. threw the laptop its not reading a sparking angle when cranking or anything

Does it show rpm. You will get spark even without an ecu plugged in. Put a sparkplug in the coil lead and earth it on the manifold and see if it has spark

[Kevspec]

yes i have done that and the spark is super weak its normally really strong but tried different coils modules and dizzy and made no difference

[Kevspec]

it also does flicker some rpm but it also likes to drop connection whilst cranking. i have always found after long periods of time connected using tunerpro it doesnt like to stay connected and also when i try log and accelerate hard and rev it also likes to drop out but i rarley use tunerpro for modifying the bin whilst car is running i use the other writing software

[delcowizzid]

Try a new relay it could be burnt and not feeding enough amps

[Kevspec]

yep tried all that no difference

Maybe check the electric pins in the ignition module plug just to rule it out. Sometimes the pins in the connector push back into the harness and don’t make contact with the module. Peel the rubber boot back and you should be able to see if its ok or not.
