engine stalling on new project. HELP NEEDED

[ccsworks]

Hi guys just bought another project along with the other five Subaru’s am working on this one is a 2007 WRX Hawkeye 2.5 it’s an x police car. The chap i bought it off has had enough of it he bought it from an auction the car was sold as non runner he gave it to his local corner garage they suspected the head gaskets and got it started and he says it was misfiring so there has been other hands on the engine . It arrived today didn’t get to spend too much time with it as they delivered it a bit late to the garage but head a quick look battery was flat put a new battery in fired it up it took around five seconds starting there was a cold start squealing noise for a bit till it wormed up and it was gone the engine is stalling like its running on three pistons had a look at the CEL it wasn’t on. I plan on doing a compression check in the morning after worming up the engine and may be a wet check as well if the compression is below 120 on any of the cylinders most vacuum pipes at the top on the EGR solenoid look ok will hope fully take the inter cooler of as well to check for any cracks or splits in the pipes i see the inlet looks different from the early models so didn’t want to miss out on anything so is there anything else which wouldn’t show on the CEL and can be faulty or looked in to.
Many thanks all help is greatly appreciated.
