Problems with a Vortec

I need algien to help me with a vortec v8 does not start with another ECU, ignition module, distributor, verify the distribution, the escape, the pressure of the fuel, and the only thing that it does is give false explosions and in 2 the cylinder 3 and 5 there is no spark in the 1 the spark is continuous and in the other normal cylinder but it does not start thank you

The first thing to help you is to tell us, the year, displacement, brand, model and fuel that your vehicle uses, the second is that you tell us how the failure happened, but from what you say about the counterclocks and the spark of the spark in my opinion it is best to put the computer to see that it accuses us, if it does not accuse the problem, the problem will not Also under these conditions the engine will not leave has not enough strength.

Hello if it serves you, check the "CKP" crankshaft sensors and "CMP" camshafts, it also verifies the ignition coils since some models bring coil by bench even if it even one.

greetings
