I got the hood sanded, but good lord is wrapping a hard skill to master...

I'm doing my best, but dang is this hard. Definitely will be a 20ft car at NASSAM.
I did purchase some wrap cut tape, which should make it lots easier.

Engine tune revision #1 is in. It is running better than ever. The knock retard is wayyyyy down. This thing pulls like a bat out of hell.

My 20ft car is quickly becoming a 10ft car!

That's a measure of distance at which it looks okay mi amigo.

Uh, yes, I know that.

Welp, I'm just gutted.
I was doing rips during shakedown #2, and lost engine power. Originally I thought I had popped a charge tube off. It's throwing codes for low fuel rail pressure, and misfires on 1, 3, and 4.

I have no idea what happened, but I hope I can fix it. I'm currently thinking contamination in the e85 (clogging injectors), a bad wire connection to the fuel pump, or the new RPM HPFP went bad. It can still drive, and the turbo spools, but sounds off and drives slow.

I'm getting these codes:
P0087 Fuel Rail System Pressure Too Low
P0300 Random Misfire Detected
P0301 Misfire on cylinder 1
P0303 Misfire on 3
P0304 Misfire on 4

That sucks man! I’m guessing NASSAM this week won’t be in your future?

Replace the fuel rail pressure sensor.

It's a brand new opel rail... Or wait... Did I reuse my old one? I'm up Pikes Peak Mountain for the race. I'll check tonight when I get home.

My wife and I are going to take the GR86 if I can't get the Sky going by then.

My apologies John. I think I misread your intial response as a misunderstanding.

No apology needed, my response was an attempt at humor that didn't work as intended.

I'm really sorry to hear that you are having problems with the car. I hope that the fuel problem turns out to be something simple.

I ordered the ACDelco fuel pressure sensor. Amazon was the cheapest AND they're delivering it today.

Huge thanks to Ssky for bringing it up and Super Serg for looking it up in the manual. Y'all are amazing. I was in a pit of despair for a bit there.

My mates and I are all waiting for the Pikes Peak Hill Climb to start.

I don’t remember if they are backwards compatible.

The sensor fits right in, and it is the original sensor from my old fuel rail.
I replaced it this morning, and it's still misfiring. The codes are slightly different though (before new fuel sensor):

After new fuel sensor:

I would say the engine runs "smoother" now, but it's still running rough.
I did a scan and am sending it to ZZP.

My best guess right now is contaminants in the e85 that went into the injectors and fuel sensor, and bunged everything up. I totally thought of buying the ZZP fuel filter ages ago too...

I'll have to get a scope down the cylinders after I get back from NASSAM.

After talking with Jason Aho at NASSAM, it looks like the new RPM HPFP may have failed. I can't wait to get home and see if that's the issue.

squilliam · 2022-07-04T23:02:19-0400

I put the OEM HPFP back on, and the car fired right up. All codes are gone, and it runs perfectly fine. I'm done with any RPM parts after this.
