6.5 won’t start I’m stumped

themadscientist · 21-02-2021, 21:00

Fresh build on the 2.0 . Everything bolted to the motor is stock with the exceptions of 880cc RC injectors, JDC COP, and full exhaust. The car ran fine for 30ish miles. Several short drives with varying load. Started the car and let it warm up for 15-20 minutes. Went to drive it got about a mile down the road and it just died.
Checked all the fuses and they’re all good.
I’m getting 40ish psi of fuel pressure
Haven’t checked spark yet. It’s the next thing to check.

Found the noise condenser is gone and a bit of exposed wire. Could this grounding out cause an issue?

Just checked for spark. I’m not getting any. It cranks just fine but no spark.
Cam sensor is an evo 8 one and it’s brand new

themadscientist · 22-02-2021, 02:11

So the rpms aren’t moving when I crank it. Seems like a crank position sensor. Any other ideas?

Checked ecu for stored fault codes?

Your on the ball

MN158261 can anyone verify this is the correct p/n for the crank position sensor?

If the noise condenser has gone and the wire has grounded it will have blown one of the big fuses in the engine bay fuse box, happened on my 4 a few years ago, cant remember whether it was a 100 amp or 40 amp but check those.

Just realised you said you had checked the fuses, but mine had exactly the same symptoms when the noise suppressor wire earthed.

Mine died when the mechanic I USED to use with her managed to short out the noise suppressor to the accel cable. I don't think mine has it any more... I can't honestly remember but my main fuse went - It's a 40A I remember that... That wasn't a fun day - barely 1/2 a mile from the garage

Best to get a new accelerator cable at the same time :P and make sure it's re-routed so it doesn't cross any wires or rub anyway

Had this at Bedford autodrome was the noise suppressor grounded and blew one of the fuses in the engine bay iirc it was ignition fuse possibly pink in.colour 15a found in the rhs engine bay fuse box iirc

Had a local motor factor deliver a few to.me at the track was fine for the rest of the day..

No spark or no spark and injector?
