Voyager Dead ... Kinda

[Paul94Z28]

Hi-

My 97 GV was running fine. 140K on the clock, needs an intake manifold gasket, used to throw the EGR code, ac no hold a charge, etc, etc..

I am driving home and it fails and will not restart, seems like no fuel. After a couple of minutes it starts and I get it home. I pull the codes and it indicates misfire cylinder #2 and lean condition (but no code). I have tried to start it a few times since. Sometimes it will not start, other times it does and I can drive it. It feels kinda sluggish though. I put a guage on the fuel rail and it is about 50 psi at idle and wot. I replaced the distributor about a year ago to get rid of a cel because of that. Plugs and wires are two years old.

Needless to say, no roadtrips until I figure this out.

Thoughts?

I would run it by Auto Zone for a free scan, it could be a crankshaft position (CPS) sensor or a camshaft position sensor, on my '98 neon the problem you describe was a bad CPS.

You must have a scanner if you are getting a misfire #2 indication. I'll second Bear's pick of a cam or crank sensor. They can and do fail regularly without generating a code. Check their wire harnesses and connections first to make sure all is well. Why were you getting a misfire code? Might be because when a cm or ck sensor goes beyond spec the PCM will kill power to the coil, injectors and O2 sensors to kill the engine and prevent excessive emissions.

It was the fuel pump - only failed when hot.

Fixed it and we are back on the road.

Can't get much leaner than no fuel from a fuel pump. Thanks for coming back and posting the fix.
