Car will crank, but no start. Checked the obvious, still nothing. (Interesting twist though)

[BgrizzlyR]

Hello all,
I have a 2001 Volvo V70 2.4T that ran perfectly fine. The other day I was driving it as normal, got back home, let it set for a few hours, and went to start it and it didn't start. The engine cranks but will not start. I have spark, fuel pressure and air. I switched out the crank sensor, cam sensor and the CVVT. I unhooked the battery and let it sit for quite some time, hooked it back up and nothing. I switched out the plugs, and coils and have full voltage going to the coils still nothing different. Funny thing… We pulled the fuel injector rail to see if it was the issue and checked its function and the engine at least attempted to fire over without the fuel rail and injectors installed!

This whole situation has got me baffled. Any help or suggestions would be greatly appreciated.

This may seem like an odd request, but I have started a few Volvos and other cars like this:

Remove the coils, spark plugs and put a cap full of engine oil down all the cylinders. (cap off a quart of oil)

Put the plugs and coils back and try and start it up.

It wont cost much and its worth a shot.

Codes stored?

We did have a code for the CVVT stored which is one of the reasons we had replaced it, but that didn't solve anything. I will report back with more info. Still feel free to add any suggestions. I'll try anything at this point.

Verified fuel pressure at the rail with a mechanical gauge?

Hrm, you said the engine fired with the injectors removed..... it might be flooding, ECT or IAT might be messed up. Crank for 5 seconds or so with the accelerator all the way to the floor, don't lift. see if it helps. If not pull fuel pump fuse and try again, if nothing, spray ether into the intake manifold and try again.
Report back. i'm curious to see whats up

Good point. Though the car doesn't have an IAT, it's fair to say that just maybe the fuel may not he regulated correctly. We are going to try a different fuel rail. Thanks

No need to try another fuel rail that's not the problem.

It's not about the fuel rail itself. This rail has a regulator attached to it, so it's really just the regulator I'm curious about. At this point, I'm covering all bases. I have access to all this stuff for either extremely cheap or free. So it's not sweat. I'm just starting to run out of ideas.

Have you tried what I suggested? putting oil down the cylinders will give you extra compression if you have fuel washed bores.

 I have started many cars this way , you have nothing to lose.

I agree, this is worth trying.

Will try tonight. I've used this remedy in the past on my 850. It's one of those Volvo quirks. Hehe

Tried putting a cap of oil in each cylinder and nothing...  replaced fuel rail nothing. Have plenty of fuel pressure. Crazy...

Disconnect pump and crank. See if it fires on ether. We need to know if it's a fuel problem or something else. This is a solid way of knowing. No need for speculation and random guesses.

We are well beyond those types of tests. Ether didn't do anything. Fuel and spark is verified to be fine. 

With that being said the next step is to see if the The TCM could be bad. It would be slightly unusual since it's the year that has the updated better ones, but it doesn't mean they couldn't go bad I guess. Thanks though anyway. I'll update when we verify our findings. Again, if anyone has any other suggestions until then, feel free to post them.
