1997 Buick Park Avenue Q&A

1997 Buick Park Avenue Question: What could be reason car wont start after replacing various parts?

Car started losing power while driving. It'd take a while to start back up. Replaced starter, solenoid, throttle position sensor, had alternator tested & replaced the 3 coils to ignition control module. What could be possibly keeping it from starting? Its like its not getting a spark. PLEASE HELP! -
Answer 1
check for spark and fuel pressure ...also scan test for codes -

Already tested for pressure. There is no spark. Already scanned for codes. I read about cam shaft sensor. Would that have anything to do with it not getting a spark? I was also told that it could be fuel pump/ or relay. Im going broke trying to fix this. -
