Hello,

I can help, how does the engine sounds while cranking? If the engine loses timing it will sound like flipper. Also, does the ignition system have good spark, please go over this video to help us get more information to help you correctly.

Please go over this and get back to us. If you upload a short video of the engine cranking while the hood is open I can tell for sure if the engine is okay. Ken

Had done all the video stuff. Got spark. Got pressure. Had someone with a better scanner stop by. He said i need to replace my ecu. Which is what i was saying but i went down step step trouble shooting. Now i just need to learn how to test ecu to see if it does need to be replaced. I work on cars not a mechanic. Had to send them away afrer telling me things i knew were wrong and wanting me to buy parts i already bought and blew me off when i tried to explain. So i want to check ecu just in case.

It sounds like the engine may have a dead cylinder but it should still run, thanks for the video, lets try unplugging the MAF sensor and crank the engine over. If this sensor shorts out it will not tell the computer to allow the engine to start. Also, I would check the fuses with the key on this guide can help.
