1987 Porsche 911 — no crank with full dash power, then it starts later

Log the conditions before you spend. Move a coil or plug on the 1987 Porsche 911 if it's cylinder-specific and see whether the code follows. Don't erase codes until someone who can help has seen them. On “no crank with full dash power, then,” that was the fork that mattered for me. This is from a 1987 Porsche 911 in Long Island with 251,500 miles. Have you gotten a second quote in writing? If your situation is the opposite, ignore me. I refuse to clear codes until someone else sees them.

Ask what changed right before it started. Write temp, speed, and in-gear vs coast when the 1987 Porsche 911 does it — then decide on parts. If the cheap test changes it, stop and reassess. I'd want a dollar figure or a measured spec, not 'should be fine.' Only after sitting overnight so far.
