This vehicle has a brand new starter, alternator, battery, spark plugs. Recently replaced timing belt, serpintine belt. It has had a ghost inside the engine for quite some time. Sometimes it will start. Right now it wont. I know it has original plug wires and ignition coil. Im wondering if i should just replace these. I pulled the plugs and spray some carb cleaner in it and it sounded like it wanted to start but still nothing. Its not pulling any codes. Ive put far to much into this motor with only 108k on it for it to keep doing this. Any ideas? Thanks!

 

Check for fuel pressure, If good, I just had a similar problem, and it was my ECU power relay#30, only $19.
