2007 Toyota Camry 2.4 won't start after head gasket replacement

Hey guys! I'm new here trying to see if anyone has any ideas. A 2007 Toyota Camry 2.4 was brought into the shop I work at smoking badly and running terrible. The car had been run hot because the radiator was busted and it blew the head gasket. So I pulled the head and sent if off to the machine shop to have it checked. They said it was badly warped across three cylinder and they resurfaced it. Now I have everything re assembled, but it simply will not start. All the timing marks on the timing chain line up where they should be. All four coils are firing. Injectors wires pulse noid lights. A few times it has hit and sputtered like it was trying to start but never successfully does. Any ideas before I start tearing it all back apart? It's driving me crazy!

Do a compression test and then double check the timing marks, again.

You did check the block deck for warp too, right?

I'd do a leakdown test and a compression test. And check the cam timing again. Also make sure you didn't bugger the wiring for the crank position sensor, and make sure you have the coil harness connectors on the correct coils. Any vacuum lines left off, such as for power brakes?

Was there any evidence of water in any of the cylinders? They may have tried to add water after the head was warped and could have bent a rod.

No unfortunately the block wasn't checked and that's kind of what I was thinking the problem is. But compression is 170-180 on all 4 cylinders. And the leak down test came back good as well. Less then 10% leakage on all four. All the spark plugs came out gas fouled though.

I would guess the timing is off.

If compression and leakdown look good and everything is firing, then I'd look very closely at the wiring harness for the coils to make sure you didn't swap a couple of them around. And you say the coils are firing, but have you checked them with a sparkplug in them? Also, if the plugs are wet, they won't fire, so you may need to clean them.

Canada

I did have the timing out. There are 3 marks on the exhaust side camshaft. One dot with an EX beside it and one dot with an IN beside. The half way in between those two is another mark just two dots. I assumed since it was the exhaust cam it would line up on the EX dot. And i didn't even realize there was the third dot in between the other two when I put it all back together. All Data doesn't specify which mark to line it up with either. But I moved it to the center two dot mark and problem solved. Runs perfect!
