For engine to fire, you must have spark fuel, and compression.
You have spark, you have fuel, have you checked for compression?

Get a compression gauge (pressure gauge), screw it in place of spark plug, and try cranking it.
You may have skipped a toothe on the belt, and the valves aren't closing fully.
You may have a burnt valve.
(That is, if you don't have good compression numbers, over 100 psi)

Are there any hydra 2.6 folks in the area who wouldn't mind trying to run my ecu in their car?

here is my thought... check the ground wire behind the intake manifold that leads from your coil and injector harness. Seriously, no cam angle sensor? Thats what my problem was this morning, I had a broken ground wire to my CAS and it did what yours is doing... always check grounds is my opinion.

Edit: speaking of harness, check and clean the connections.

Thank you, but there is no CAS on my 03.

Here is what happened: When you were cruising and then applied throttle, something probably happened to the timing belt, the engine stopped running, but the rpms still showed because you were still in gear and the crank sensor was still picking up a signal until you shifted to neutral and the engine stopped and rpms went to 0 because the engine wasn't firing/running due to something wrong with your belt.

You said that your belt looked okay, but did you make FOR SURE that the cams are turning when cranking?

It could also be a jumped tooth. IDK if this applies to you VVT NB people, but to check your teeth easily, all you have to do is remove your valve cover, set cyl 1 to top dead center by putting a rod down the spark plug hole, and look for 19 teeth between the grooves on each pulley.

Good luck

Welp I did a compression test and compression was 160 across all cylinders so that rules out timing problems right?

Make sure your intake cam is turning - when you put the new timing belt on, did you remember to torque the cam gear bolt down to 45 ft-lbs? if your cam gear is turning, you will get spark and fuel, b/c your ECU sees your engine position based on your intake cam gear. If the cam itself isnt turning, you will get no intake charge, and no fuel in the cylinders.

Perhaps it's a dead MAP sensor if you've converted to map. That's about all I can think of.

What happened to the injector theory. My car did The exact same ****** ******* thing (driving nice one minute, the next it feels all sorts of weird when I step on the gas and then dies when I take it out of gear), we even towed it home. She wanted to start but wouldn't. I eventually found one of the wires on the harness for the injectors came off. Soldered that bitch back on and was good to go on the second try.

MAP sensor is ok as confirmed in Hydra and gauge. There is no MAF.

Wut?

So one fucked wire made all your other injectors **** up?

OK let me eyeball every motherfucking wire on them bitches. Annoyingly I have clip in injectors, they weren't soldered in. This did happen shortly after I fixed an injector vacuum leak tho...

They all should have 12v on one side of the plug, while the PCM grounds the other side...... If the hydra is built like most OEM PCM's that is.

Hmm how do you check for voltage? I've never messed with electrical stuff before so I need noob instructions plez.

With a digital multimeter. Do yourself a favor and hit up your local community college. They normally have decent automotive programs for new guys.

i know this may not be the problem but your alternator could be dead, and when your cranking, your cranking from the battery and not getting enough juice to get it going...... just throwin that out there..

Pull it off and take it to an auto parts store. Flip your lights on. If they don't go dim while your cranking, you still have more then enough juice.

Measure voltage with engine off, cranking, running, and revving.
Report back.
