engine/fueling problems got me stumped

[proace111]

hey guys hope you can help i've got a jdm gt rs legacy , i went to start it one morning, it wouldn't start tried it later in the day and it went , since that time its been parked at work not wanting to start so far i've replaced spark plugs(way over due), fuel pump (weak fuel pressure, and starts off eather) and the cam angle sensor (fault codes from the computer sent them) .basicly neither of these thing have done it and i' m stuck on what to try next, and not really keen on spending big bucks at an auto electrician . so any advice towards a solution would be awsome cheers

How many miles/kilometers are on the car? Does the car crank, but just not start? If you spray starting fluid in the intake will it start? Have you checked for spark on the plugs?

The coolant temp sensor plays a pretty big role in the engine's AFR and starting. If it is bad, that may be a possible cause. Try unplugging the electrical connector and see if the engines starts. It may start in a "fail safe mode", but might start if that's the problem.

Also, what is the ambient temperature when you're trying to start it?
