1972 Chevrolet C10 — first HPDE in a stock street car

Ask what changed right before it started. Loaded-suspension checks on the 1972 Chevrolet C10 catch play that a wheels-hanging inspection misses. Save the big job until that test fails. This is from a 1972 Chevrolet C10 in Northern Virginia. If it doesn't change the out-the-door or the repair estimate, it's noise. Heat soak after errands is the other window.

If it were in my driveway, capture voltage while the 1972 Chevrolet C10 is actually failing — after it restarts you've lost the clue. You'll know quickly if you're on the wrong tree. I'd want that in writing, not as a promise. I'd sleep better after that step, even if it finds nothing. Wrote this up on my lunch break.

Log the conditions before you spend. Swap the cheap/easy piece first on the 1972 Chevrolet C10 and see if the fault moves. Don't erase codes until someone who can help has seen them. On “first hpde in a stock street car,” that was the fork that mattered for me. Post the numbers (or the code) and people can get more specific. I'd rather look cautious in this thread than stuck later.

I'd want a measurement, not a hunch. A pressure test beats staring at a dry driveway if the 1972 Chevrolet C10 is losing coolant with no puddle. That's the branch I'd chase this week. This is from a 1972 Chevrolet C10 in Northern Virginia. I'd want a dollar figure or a measured spec, not 'should be fine.' I'd rather look cautious in this thread than stuck later.

I'd want a measurement, not a hunch. Loaded-suspension checks on the 1972 Chevrolet C10 catch play that a wheels-hanging inspection misses. If the cheap test changes it, stop and reassess. That's the sequence I'd use. I'd rather be boring and correct. I keep a notes app thread for this now.

This is usually cheaper to test than to guess. Move a coil or plug on the 1972 Chevrolet C10 if it's cylinder-specific and see whether the code follows. If the cheap test changes it, stop and reassess. Do that first. I already checked the easy fluid levels.

Intermittent stuff lies if you only catch it once. Capture voltage while the 1972 Chevrolet C10 is actually failing — after it restarts you've lost the clue. If the cheap test changes it, stop and reassess. On “first hpde in a stock street car,” that was the fork that mattered for me. Verbal 'we'll take care of it' is not a plan. Might be overthinking it, but I'd rather overthink than overspend.

If it were in my driveway, loaded-suspension checks on the 1972 Chevrolet C10 catch play that a wheels-hanging inspection misses. Don't erase codes until someone who can help has seen them. Do that first. If that fails I'll eat the diagnostic fee.

This is usually cheaper to test than to guess. Two 1972 Chevrolet C10s can feel identical and have different causes, so measure before you copy someone else's repair. That's the branch I'd chase this week. I'd want a dollar figure or a measured spec, not 'should be fine.' Trying not to diagnose from the couch.

Log the conditions before you spend. Get a real battery/charging test on the 1972 Chevrolet C10, not just resting voltage, before blaming a module. Save the big job until that test fails. On “first hpde in a stock street car,” that was the fork that mattered for me. If they can't show the line item, I assume it's hiding. No warning lights, which is why I'm documenting it.

I'll poke at it this weekend.

Start with the test that can prove you wrong. Get a real battery/charging test on the 1972 Chevrolet C10, not just resting voltage, before blaming a module. You'll know quickly if you're on the wrong tree. This is from a 1972 Chevrolet C10 in Northern Virginia. That's the whole play. Your commute and mine probably aren't the same, but the test still applies. Trying not to diagnose from the couch.

Log the conditions before you spend. Two 1972 Chevrolet C10s can feel identical and have different causes, so measure before you copy someone else's repair. Save the big job until that test fails.

Cleared nothing. I want service to see the alert on the 1972 Chevrolet C10 first. Wrote this up on my lunch break.

That's the branch I'd chase this week. If they can't show the line item, I assume it's hiding. Doing the boring step first on purpose.

OP update: scanned the 1972 Chevrolet C10 again and still only have the one pending code, no new lights. I'm keeping receipts and dates in one folder.

This is from a 1972 Chevrolet C10 in Northern Virginia. Run the total, not the monthly, before you commit. That's coming from doing this as an owner, not a shop. If this is nothing, great. I want that in data.
