There are probably about a hundred threads here about this topic, but it's difficult to choose the correct words that will find them in a search.
I feel dumb that I can't figure out my problem and would appreciate your suggestions. The car ran in May. I have since had the camshafts out. Now that I've put it back together, I can't get it to start.
Camshafts have been out twice. First in April to replace intake oil seal and one exhaust shim. After putting them back in and starting the car, I had a problem. I had popped the split ring that the alternator drive pulley bears against off of the camshaft unknowingly. It was rotating and shaving bits off the head (no real damage) but then destroyed the new oil seal and (worse) damaged the groove in the camshaft that the ring sits in.
So I took it apart a second time and consulted with an engine shop to get it fixed. While at it, I took the exhaust cam off also and took it to the shop along with the intake cam to have them characterized, since I didn't know the specifications of these non-stock cams and the shop could do it.
Re-installing them, I got to a point where I realized that I had somehow lost my TDC setting on the crankshaft. It had moved. So, I removed the camshafts, (valves are closed then, so you can turn the crankshaft all you want, right?) set it back at TDC, and re-installed the camshafts in the orientation that I had recorded with photos when at TDC. Timing marks on the sprockets aligned with one another. I thought, "ok, fine!"
-I turned it over by hand. Fine
-I re-set the distributor on the jackshaft to the correct position for TDC
-Using a lamp, I connected it between +12 and the (disconnected) low-voltage distributor wire, and set the timing at 5deg BTDC static. The lobe on the #4 cyl exhaust cam was pointing inward toward the intake.
-re-connected the low-voltage distributor wire.
It wouldn't start.
Since, I have:
- Checked the timing with a timing light as I crank: looks great. @ 5deg BTDC.
- Checked for spark with inline spark-testing gizmo on cyl #1 and #2. Fine.
- Pulled the fuel hose off of the outlet of the pump (rebuilt last year) and verified that there's pressure there when cranking. Fine.
- Checked compression on #1 cylinder. Fine
But it doesn't start. Doesn't fire at all. Cranks over fine. I'm stumped. It's hard to imagine that it's not some timing issue, but I can't see what. Thank you for any suggestions!
