OK, first Post here, but a bit of experience w/ the 420A engine. A summary:
Just a recap of what has gone on so far:
1. Water pump failed fall of 2008 , trashing valves.
2. Engine had 197k miles on it, so i decided to do a full rebuild
3. New Valves, valve seals, rings, all new seals and gaskets. Head, crank, and block sent to shop. New starter motor, oil pump, water pump, head gasket, head bolts, ignition wires, spark plugs, etc
4. Put it all back together, started on first try. Drove it ~120 miles. Ran well, but was burning oil in Cyl#2. Looks like Rings were not gapped well enough.
5. Decided to replace the rings in Cyl#2. Pulled head and Cylinder#2, replaced rings on it. New Head gasket and head bolts.
6. Put everything back together again, but timing was 180 deg off (timing marks were on the outside rather than inwards towards each other). And was getting no spark... I had hand rotated the crank before hand, and nothing was binding, so no valves should of been damaged. During this the Camshaft angle sensor was replaced with a new one.
7. Unmounted engine and pulled timing and found out my errors. Timed correctly and mounted engine. Tested Compression in all cylinders to verify no damage was done with 180deg off timing before, and it's good on all cylinders. Tested resistance in all coils
8. -Now... Can crank all day long(ok well, until the battery wears down), but no spark. There is fuel present at the rail w/pressure. Looked for quite a while for something unplugged, but nothing I can see.
What else can I check? I need to get this out of my garage. Any help is greatly appreciated. Pics can be provided if your interested. Here's some I've taken along the way:
Perfected Insanity: Blue Hot
Perfected Insanity: Where's Your Head At?
Perfected Insanity: Slick Move
Perfected Insanity: Lost my head again.
