1998 S70 T5 turned into a brick

I've been all over multiple sites investigating this so bear with me:

Broke passenger side halfshaft a few weeks ago. Had it running in the parking lot where it happened. Towed it home. R&R half shaft and front axle brake job. Now I have a crank, no start situation.

*Fuel pressure good
*Good spark
*New cam and crank sensors (wires chaffed)
*Compression170-180 on all but #3 120-130
*Dumped a bit of oil in #3
*runs on starting fluid
*Battery voltage is good
*Fuel pump relay is new, jumped it as well
*Tested every fuse with multimeter(ohms)

I am at a loss here anyone have any ideas?

Does it smell like unburnt fuel at the exhaust? If not, then the injectors are likely not firing.

Sorry I dint post, injectors are not firing as far as I can tell
with a test light

Double check those cam and crank sensors, if I remember correctly, one (or both) of them is required to pulse the injectors. Verify signal output from them. Are they OEM or aftermarket?

I’ll check them when I get home tomorrow. The thing that is killing me is it ran before the axle replacement . One has nothing to do with the other. Lol

Check all your fuses and connectors too.

You state it runs on starter fluid. Have you looked at the fuel pump and/or fuel filter? Can you hear the pump turn on?

I would think that if the mentioned sensors were bad it wouldn't fire with starter fluid.

It could have nothing to do with each other. Might be fuel pump/injector related just from sitting.

The fact it starts on starter fluid means it has to be a fuel issue.

Fuel filter is less than 1000 miles old. Pump is good.
