I need some other mechanic help. I am a mechanic myself but i can not figure out my own car issue. I have had the car for 3 years now. It has all brand new engine parts from 3 years ago when it was rebuilt before i bought the car. The only thing that was still original was the block. So pretty much it only has 30,000 miles round estimate. Last summer i did a tune up just because i was bored. I put a new main relay, alternator, new anti-freeze, plug wires, tires, radio, exhaust, front brakes. So about 3 months ago i went to sonic to get some food and i put it in park. It was still running for like 15 mins then just shut off/died. Four nights before i went to the park across town and shut it of then it started up when i left and i went ten feet then it did the same thing. So i have not had till now to mess with it cause i got married, and etc. So yesterday i pulled in to my shop and put a new fuel pump in it cause i noticed it went out too. But now it still will not start. Its primed and everything. Has psi pressure everything has fuel going to it. So whats the problem. When everything happen the check engine light never came on. It still wont come on. I have to check the codes by a blue plug on the passenger side floor board with a paper clip but nothing flashes. I have now clue what the issue is i can't figure it out at all. Please help. Thank you !

 

Have you checked the fuel pump or filter. Does it just die or sputter like it's missing then die?

 

Yes i check the new pump before i bought it today, it worked, it was loud as can be. The car just dies while driving or in park, no stalling at all. I even replaced the thermostat because it failed. But idk what to do.

I assume you checked for spark? Try spraying starting fluid into throttle body, see if it starts. If it does, i would suspect fuel, if not, I would suspect spark or compression.
