My 1996 tahoe has very little spark out of the coil?

Question

I have tried three different coils but have the same problem not enough juice to send spark to the plugs have also changed the knock senser the camshaft and crankshaft senser. what would cause it to do this?

Answer 1

before replacing check power/voltage/grd going to coil. also resistance.

Answer 2

Check the distributor cap and rotor. They are prone to burn through after a while.

How many volts and what brand of coil are you using? If the coil is firing then all the sensors are working.

Answer 3

stop throwing parts at it...Why didn't just the ecu.

take it to a professional.
