Exclamation weird car died when driving...

Ok so I'm on the way to the park on this windy 3mile road going 35-45 mph. Car ahead of me was going extremely slow. I get over and punch it, to pass the car up and accel was kin of poor. Few mins later car just looses power like symptoms of being out of fuel. I had more than half tank left. Thinking my fuel pump is beggining to fail? Injectors still stock, I do have 36lbs sitting now just hadn't had the time to get another tune. Any ideass? Might have to order that racetronix fuel pump kit sooner than in thought.

Test your fuel pressure before you buy a new pump. Test for spark at the coil while you are at it.

Might be a fuel problem under load.
Could also be the ICM.

thats been happening to me the last few weeks turns out it was a bad coil. I also agree with the previous post...do the basic tests first and check for codes!

Engine light didn't come on so would there be codes up still? Any basic fuel pressure tester would work right? And how to check coil for spark? Sorry not very tech savvy.

It's possible.
Yeah, screw it onto the schrader vlave of your fuel rail.
Testing for spark at the coil isn't needed. I didn't know that your car started back up again. You can test the continuity of the coil though.

Cool. Thanks man. Ill stop by the parts store for that tester. The how to's on shbox's website should guide me the rst of the way. Thanks again man, ill let you know the results of both tests

Scratch it. I'll just order the racetronix kit end of next week. I don't feel like spending 45bucks to find out i have to spend the 200bucks i was anyways down the road for the new fuel pump kit. I'll just try and test the continuity of the coil tonight if i can.

Alright tested fuel pressure.. held steady at 40psi idle and a little below 40psi under a load. Haven't checked the coil yet tho...
