'96 Intrepid no-start

As you can probably guess, you really need fuel pressure, and you really
need 3 sparks each revolution. Just keep looking until you're sure you've
got one and not the other.

The very first thing I asked about was if it was sparking, and without
any tools onhand I went towards the fuel pump. No life from the pump
and very little from the ignition (apparently). My next thought was
crank/cam sensor but not knowing the engine, I had no idea if it even
had one or not. *shrug*

Fuel pressure should come up before you start it. Every car is like that.
When you turn the switch on it should run. If it doesn't run, direct feed
it some power.

Ah, shouldn't the system prime even if one of the sensors IS bad? I
cycled the key from off to run several times, taking the key all the
way out each time, and was greeted with nothing from the shrader valve
on the fuel rail.

Personally, I've been having some trouble with coils once in a while. I had
a problem where my coil drew enough amps to blow the ECM fuse. You might
check that fuse.

I'll try the fuse. He mentioned that someone had tried a different
coil pack, although if it took out the fuse then replacing the part
certainly wouldn't help.

It has both a cam and crank sensor. When you start it, after everything
turns over, it figures out where it is. If the cam and crank sensors aren't
aligned, it'll never sync up and it won't start. So there's one
possibility, jumped timing or a broken timing belt. It's pretty easy to
check. The front engine cover is split at the crank, so you can that whole
thing off without doing a whole lot to the front of the engine. There's
also a little piece of the front cover that allows you to see the belt up in
the upper right corner.

Still, there should be *some* pressure at the rail shouldn't there?

The two sensors could be at fault. I don't know if they'd set a code in the
condition you've got, where the engine won't run. Hard to say.

It has both. Crank sensor is on the lower rear passenger's side of the
block near the transmission bellhousing. Cam sensor is the most obvious
thing sticking up from the top of the driver's side cam gear cover.

Yes, the system should prime after you turn on the key and before
starting the engine. The fact that it doesn't points to a fuel pump,
fuel pump relay, or auto-shutdown relay failure. Check the relays first,
they're cheap and easy.

While checking for fuel pressure I swapped the FP relay with the A/C
relay (supposedly the A/C worked) which didn't help. The auto-shutdown
relay is a great idea though, I hadn't considered that and it does
make sense. I loaned the owner my battery charger today, so hopefully
we'll check out a few things this week.
