timing
 

2000 gallant. Broke timing belt. I replaced it & car will not ttart. Took it off turned engine 180, still no start. It sounds as if it had no spark. Checked plugs/coils OK.. Any thoughts?

uhhh....
Tdc #1.
Line up your cams.
Belt on.
Check compression.

If you broke it while running, id expect a fair bit of damage.
If it has a dizzy, and no spark, id expect you sheared the drive pinion key.

Tdc yes.
All pulleys on mark, yes
Sounds like no compression, lady said it always sounded that way.
Broke while d, yes. I'll check drive pinion key-compression. Thanx

Ooh, yes there is spark, dizzy?

If theres spark then its unlikely to be dizzy issue.

Compression check low. Cyl 2 & 3 below 100. Took head off. Head gasket looks OK. No damage to valves or pistons. What else could cause low compression?

leakdown test.
'looks ok' doesnt always mean ok.
What did the bores on 2&3 look like? Shat a ring?

Cyl. Smooth. If it is the rings would it show on the bore?

That is an interference motor .... U may have internal damage dude,..Good luck.

maybe. maybe not.
that's why we do leakdown tests.
