  1. Starter Only Engages For A Second

    The engine does not appear to be kicking back? What would cause that? Like a misfire from off timing?
  2. Starter Only Engages For A Second

    So, this is a weird problem. We just did a head gasket on our high school shop gsx and after we finished it now only cranks for a split second and then the starter disengages. It does it consistently. If we try again it will crank for a split second (less than one second) and then the starter...
  3. 2G GHS GSX Shop Project- Tuning/Idle Help

    Head gasket replacement in progress. No visual sign of issues. Chambers held fluid tightly. Hoping for the best. Bought ANOTHER felpro permatorque gasket. (Those are expensive!).Stay tuned. Only 2 weeks left with my seniors. 3 weeks total...
  4. 2G GHS GSX Shop Project- Tuning/Idle Help

    Yup, that's what we did last time. Everything sealed fine. So, we'll pull the head, check for warpage again, last time we even replaced the rings because we didn't want to pull the head and not know why we had low compression. I have more rings, we could do it again, but I don't see why we'd...

    Yeah, we did a leak test with the head off. Put fluid in the combustion chamber and it held fine. I may have the kids to a leakdown test before disassembly.

    So, we're beginning teardown. Hopefully we can figure out WHY we had low compression..
  7. 2G GHS GSX Shop Project- Tuning/Idle Help

    So after all this, we tried the Blue Devil head gasket fix.... and now we have fine compression on cylinder 2, but low compression on cylinder 4?!?!?! That was the cylinder that we previously had low compression on. We did new rings and a head gasket and we bought the best gasket we could...

    Thanfully we have 0% milkshake... no boys in this yard.And yes, a couple studs were loose. I do have a bottle of the Blue Devil sealer on the shelf. And IMHO, I'd rather swap a radiator (we have an extra) than do the head gasket again... but this is shop class. The kids are learning.
  9. 2G GHS GSX Shop Project- Tuning/Idle Help

    One problem we may have had was that we used moly assembly lube with our arp head studs. I don' even remember what torque we put them to, but I remember that I did a lot of research so that we had hopefully done it correctly.
  10. 2G GHS GSX Shop Project- Tuning/Idle Help

    PROGRESS (but not the kind I wanted)So, after adjusting the MAF adjustment, I felt like there as some improvement, but then I started thinking... We are inside and hooked up to a vehicle ventilation system. I unhooked our exhaust tube and lo and behold, white smoke. Not horrifically bad, but...
  11. 2G GHS GSX Shop Project- Tuning/Idle Help

    Yeah, I've never messed with the MAF slider. That is the way the chip was burned. I can zero that out.

    OK, from reading around... things to check-ICM Recheck ISC CASI have another ICM on a parts car. I've tested the ISC before, but can do it again. I would hope out CAS works, it is band new...

    Here's with STFT and LTFT... I forgot to turn it off, so it is long, but you can see what it looked like at the beginning.

    I hooked up the WBO2 to the rear o2 sensor wires. Here is the log-
  15. 2G GHS GSX Shop Project- Tuning/Idle Help

    So, from what I have watched, the fuel pressure stays at 42.5-44 (hard to tell on that small dial. I think we have it set between 42-44.).The wideband sits pretty happily between 12-13:1 when warming up. That said, if anyone wants to save me the horrifically difficult job of hitting the search...
