My Rover is Dead

Before you go off buying all new electronics, try a new fuse box under the hood. I've heard of them going bad and I even replaced mine when I was fighting with my CKP. Honestly still don't know if it was the sensor, the fuse box, or the wiring that fixed my problem since at the end of my three days laying in the snow I laid hands on all three when she finally started.

You have spark, but no start. You have fuel pressure, but no start. You changed CKP sensor, but no start. It is pretty low probability, but you might have a bad ECU.
Try this, buy a replacement ECU/BCU/Inst Cluster set off ebay, see if your trucks starts. If it does, sell your BCU and Inst cluster on ebay. If it does not, you can always resell the parts on ebay.
Or, squirt a little gas through the throttle body, see if it hits. If you have spark and compression it will fire/hit, even if it only runs a couple seconds.

Okay did some more trouble shooting last night.
1. checked battery after charging and getting 12.7 Volts.
2. unbolted fuse box under hood and cleaned and inspected wires for damage or loose connection,
all looked good.
3. tested all fuses, all good.
4. pulled all plug wires (one at a time) checked for spark with extra plug, its getting spark (kind of weak)
5.fuel pump is running during cranking but not priming when key is first turned on.
6.with the wife cranking pushed in Schrader valve up by purge sensor, No fuel coming out, is there another way to check pressure?
7.Took boot of intake manifold and squirt fuel past throttle plate. Crank it over and not even attempted to start. shot starter fluid in there with wife cranking, nothing.
looking for code reader now.
the injectors must not be firing, does anyone know how to check that?
Also is there a CAM position sensor?
Thanks for the replys

All the big autoparts stores will read codes for free - Advance, O'reilly, AZ
Yes, below water pump and above crank pulley

How do you know it is running during cranking?
(I unplugged it and checked volts, I believe it was 9.5 I plugged it back in and unplugged the fuel line and just bumped it over and fuel came out of pump.)
You can rent/borrow a fuel pressure gauge at O'reilly. If there is no fuel the pump is not running
( I'll try a find a gauge but pushing in the valve should have something right? is there more then one Schrader valve?)
If you it doesn't pop then you are not getting a spark.
(That's what I thought so i check it again and it does spark when cranked, weak though)

You can pull an injector out of the manifold or get a spare and plug it in to to wiring plug - you can see the injector squirting.

If you look at this photo you can see the schrader valve for the injectors http://files1.kyozou.com/pictures/_2...6/21545056.jpg
There is a valve with a green cap on it that is the vapor purge line, that won't have any fuel in it.
If you have not downloaded the Rave manual, you need to. You can see more diagrams there.

Not sure of that, search the archives. You can buy a code reader off of Amazon for $5, search for a Elm 327 OBD2 bluetooth reader - you can download the free torque app for Android (buy an old Android phone off of ebay). You need to get the codes read. Based on the symptoms you are reporting I suspect a bad crank or cam sensor - assuming there is fuel pressure. They control the injectors. I will reiterate however, if you squirt fuel down the throttle body and there is spark, it will at least pop. Reconsider my advice on the ECU - using used parts off of ebay is like testing for free - you can always resell them.

Sounds like a bad fuel pump to me but you may want to confirm by giving it a shot of starting fluid and see if it fires.
