Hello Cecil

How are you doing? Did you have an engine scan before the parts replacement? I believe you did replace the key components to correct this issue but still the problem persist.  I'll be standing by for your response.

Thank you

Hi Cecil

Good to hear back from you... If the engine starts to sputter, is the temp normal? Sometimes overheating is the cause of this. Does it have any history of ECM replacement?

Hello

If it has no spark then it has to be the crankshaft sensor. But it's been replaced right? I am thinking that the problem is the ECM. It may not be giving the right signal to the sensors that's why it won't run properly even with new parts. I would suggest an ECM replacement for this Cecil. Nothing else I see in here but the ECM.
