1997 gc8 turns over but wont start! Need help
 

Hi guys, have searched most of the forum and haven't found anything close to the troubles I am having.

Problem started after changing spark plugs.
Original problem started when I changed spark plugs, would start and run at idle but as soon as it dropped below 1krpm it would slowly die the stall, changed to another set of plugs and brand new leads and same problem.

When checking I found a bunch of old and broken vacuum lines under the manifold, so pulled the manifold and ran all new fuel lines and vac and boost lines and had injectors cleaned and checked.

Put it all back together and nothing! Turns over but wont start.
Has fuel (and checked pulse at injector plug, new filter)
Has spark (replaced igniter and triple chacked spark)
All plugs on manifold and being cleaned and checked
Has no cel codes
Replaced battrey
Doesn't have immobilizer

Looking for ideas of what else to check or try.

Cheers

Crank angle / cam sensor

Thought that, but no codes. Only other thought I have had is it may have jump a tooth on timing.

Check the vacuum line connections as well as any loose electrical connections

Re pulled the intake last night and re checked everything and cleaned all connections again.

Checked the main engine fuse at the front of the fuse box that sits under the bonnet? it's the one that has screws or small bolts holding it in place from memory, I've had a couple go on me over the years.

Are you def getting fuel to the injectors?

Fuse is ok and injectors have pulse and spark plugs are wet.

Did you put tge spark leads in the correct places.

personally i would pull a fuel line and check for fuel flow just to make sure.

Yeah checked fuel again today and its pumping and rechecked leads aswell and they are run correctly as well.

mmmm my mate had a early gc8 95 not starting once ended up being a problem in the wiring loom just from age after much investigation and frustration...

My fear too,

And you're positive it's not a cam or crank sensor?

No codes for it, but going to drop in a cam sensor on the weekend and check compression
