lost all engine power, broke down, died.
 
So I was happily cruising along the highway a few minutes ago at about 60mph, 15pct throttle when I felt the car loose all power. I coasted down to the side of the road and when I put the clutch in and dropped to neutral the rpm when all the way to zero.

Checked the plugs and they look ok. My new gates timing belt also looked ok from what I could see without taking off the cover. Wtf!?!? Suggestions? I am out of AAA tows for the year :( I am thinking maybe clogged fuel filter but the plugs were a bit wet so I dunno what's up. Everything looks aok in the hydra. FML

Come on I know you guys love helping out on mystery bullshit problems like these.

Will the engine turn? Check spark? Running out of fuel generally kills it slowly, not suddenly, although the two times my fuel pump cut off on me I was idling. Plus as you said the plugs are wet.

Faeflora 05-09-2010 03:04 PM

Yup I can crank it but it doesn't catch.

Noob question. How do you check for spark? Read the suggestion a bunch o times but never learned how to do it

curly 05-09-2010 03:07 PM

Pull a spark plug, put it back in the wire or COP, lay the threads on the valve cover so you can see them from the driver seat, and crank it. You should see a spark jump across. If you have the time, do it with all four, you can do it all at once too.

I would suspect something like a cam position sensor and imagine that your Hydra has some sort of diagnostics mode when hooked to your laptop which would allow you to check for cam and crank signals coming in.

Sparetire 05-09-2010 04:49 PM

The pushing in the clutch precipitated the stall?

Just for kicks, try to wiggle your crank pulley a bit.

My guess is sensor related too though.

The no start is rather a simple problem.
It's either air, fuel, or spark.
You'll need a helping hand (or two), and, just crank it over while checking for spark.
If that doesn't work, pull the fuel lines to check for fuel.

I once had to be towed because the plug for my coil pack was not on 100% tight. A nice $80 lesson. :)

Any updates?

Faeflora 05-20-2010 11:15 PM

OK updates. No good news.

I have spark

I have fuel pressure at the rail

Timing/compression is aok (160 dry while cranking across all cylinders)


Problem is

No injectors are firing :( :( :(

Not sure what to do. :|

na8psi 05-20-2010 11:22 PM

Just to clarify, you have fuel at the rail, and by fuel I mean correct pressure not just fuel getting there? You are NOT getting fuel past the rail through the injectors?

righteo.

na8psi 05-21-2010 12:41 AM

You tried pulling the injectors out of the rail, and putting in another set? I dont know much about your engine management so I have a feeling its possibly something dealing with that commanding the pulsewidths. Sorry I cant be much of help.

Faeflora 05-21-2010 01:20 AM

If I can find my factory injectors, I will but the thing is all 4 are dead. My wiring for the injectors looks ok (plug and play rc750) so my guess is something with the hydra itself or the hydra wiring :(

pschmidt 05-21-2010 07:24 AM

You checked the injector fuse under the hood?

I have a set of 99 injectors if you want to give them a go.

Laur3ns 05-21-2010 07:37 AM

Log a crank session. Is the Hydra at least trying to send a pulse to the injectors?

You mean like does the noid light flash? It does.

Faeflora 05-22-2010 11:24 AM

OK I think I have an idea of what this could be.

When I bought the car, it had a aftermarket alarm Directd Viper installed. There's still a bunch of wire fuckage from that install underneath the steering column. My thought is that some anti theft bullshit activated.

The problem is that it's a real rats nest under there-- the install doesn't look that clean. Tracing all this crap out is going to not be fun. Does anyone have a wiring diagram for the immobilizer system etc? I just want to put this antitheft system shit back to stock. I checked at the directd website but of course I need a login/pass to get access to the actual install docs.

molitar 05-22-2010 03:16 PM

Dumb question - but do some accessories not work as well? fan for instance? You may want to check your Main Relay by the engine fuel compartment.. I had mine go out and it killed the entire car...

Faeflora 05-24-2010 05:49 PM

Ok so new info

Its not the alarm- that just disables the starter not the inectors

Spark is ok and validated via curly method

Injectors are ok I can smell the fuel

Crank angle sensor is ok since rpms readout in the hydra aok

There is no CAS

When I try to crank it goes eh eh eh eh eh whirrrr then repeats. Does this mean timing is out of phase? Ideas pleeez
