2001 sub sohc. timing belt popped. Got it towed home. New timing belt. Figured even if it had bent valves it would at least run badly. It has gas and spark but absolutely no start. Checked timing belt 3 times and it was installed correctly. 2 days of trying this and that no luck. Any Ideas helpful. Thanks

You sure the timing is correct?

Using the dash marks for timing or the Arrows? You should use the dash marks.

Anybody got any pics. I figured by lining up the marks on the cam pulleys and crank pulley I would be good.

 

[brokesub72]

I used the dash marks and not the arrow. That I had pointed to the right.

Never done anything with timing on an engine, sit tight I'm sure someone will chime in.

you need to count teeth if the marks are no longer on the timing belt.

see here for your manual

The timing marks are on the belt. It's brand new. And I aligned them with the marks on the cam and main shaft.

pull the codes off the ECU

I have to pick up a code reader.

Since the belt came off, have you tried turning the motor over by hand?

 

[BackWoodsBob]

I have to pick up a code reader.

Local auto parts store should pull them for free... or you could 'rent' one instead of buying it for this task alone.

I have put a new belt on and it turns over but will not start. You can't rent them any more you have to buy them now.

It has fuel and spark, 3rd thing to check is compression. Compression testers are fairly cheap and immensely helpful. I've had my engine not start due to just 1 cylinder w/no compression(dropped valve). Try cracking the throttle a tad when cranking and see if it starts then.

Wait, so your saying your timing belt broke, and you just replaced it and expect it to start? If your valves are bent, which they are. then you have no compression, and if you have no compression guess what your not gonna do.

Start with a compression test. I believe normal is about 160-180 IIRC. If these are not your numbers I guess you know where you sit.

 

[Jagular 1785]

If your timing belt broke while the engine was running, 95% sure you have bent valves, especially on the EJ251 which is listed as an interference engine. Definitely do a compression test, but I'm positive that you'll be pulling the heads and replacing valves.

 

[BRZCory]

how are you testing for gas and spark?

also, timing belts are a lot more lenient than most give them credit for. If you're off by a tooth or three, it'll still start but it'll run poorly. I've set them by just pointing the marks on all 3 pulleys straight up before (without the lines on the belt itself).

On a positive note I'll be selling an 01 2.5sohc with slight piston slap in about a month
