Hey guys, yesterday morning on the way home from my friends house my car decided to randomly just shut off. I had just filled up on E85 about an hour prior and during the 40-50 mile drive the car showed zero signs of anything being wrong. I was beginning to climb a large/long hill about 3-4 miles from my house and the rpm's just dropped and then all my ACD turned on. I pulled over as quickly as I could because I had a pack of cars right behind me and with the car just about dead and it being an incline it wasn't the safest task When I finally got parked, I tried to start the car and all it would do is just crank, crank, crank, crank, and crank but no start. I didn't even get a CEL so I'm a bit confused Any ideas of what it could possibly be? I pulled off the cam cover to make sure the belt didn't snap and thankfully it didn't. It's a 2006 Evo IX with 133k miles on the stock block/head. Could it be the coilpacks? Fuel pump? I just changed the fuel pump within the last year so it has about 10-15k miles on it maybe. I also pulled the sparkplugs and they look fine as well (no missing pieces).

Thanks in advance for the help

 

check the ignition fuse by your left knee behind that coin cup

no CEL at all?

 

Will do Nope, no CEL whatsoever.

 

that's weird

if the fuel pump dies, crank angle sensor or cam angle crapped out that would throw a CEL.....hhhhhhmmmmm

your timing belt is still in tact?

 

Yeah, I had my friend crank the car while I looked at the belt and it was fine.

 

then im thinking it might be the FPR or maybe the fuel filter it self.

 

Did you check the glove compartment?

 

Crank angle sensor...symptoms lead in that direction. I'd bet money on it.

It's located in the timing belt area, going to have to remove belts and pullies to get to it.

 

Hmmm, I might have used the fuel filter that walbro provided instead of the oem one now that I think about it.
To see if the map switched? There's nothing really in there lol
Wouldn't that trigger a CEL?

 

Not always will there be a CEL. When it happened to me I didn't have a cel, then a day later i finally got a stored cel related to Maf/intake temp sensor. Make sure you're pulling codes with a Good OBD II scanner.

I hope it's not your CAS...not easy but not the end of the world.

 

my crank angle sensor didn't throw a code because the wire was cut. I recommend checking that anytime you have this sort of issue. I have a thread about this from 5years ago somewhere on evom.

 

Similar symptoms?

 

I just cranked the car a few times and disconnected the fuel return line and nothing came out. Looks like the fuel pump is bad

 

If there is no Cam or crank signal the fuel pump does not turn on.

 

Not your fuel pump...ecu has disabled power to it. Precautionary
