Having problems with your 1997 Pontiac Sunfire ?

I have a 97 sunfire 2.4, today it decided it just wasn't going to start

\015 Ok so I hade a check engine light, checked it with a scanner and it read random/multiple cylinder misfire. I'm normally pretty car savvy but as long as I've had this car anytime I have a problem I get stumped. I pulled the coils and tested them to spec, both tested fine, tested the module, that tested fine, inspected the "coil housing" no cracks. put it all back together and now the car just wont start. A coworker who is familiar with these cars tried the passlock reset but it didn't do anything. \012 Now here's the extra info. My timing chain guides have been worn and in need of replacement for a while but it ran and I couldn't afford to get it done so I've been putting it off. When I turn the key the engine doesn't crank but the serp belt turns and you can hear the starter(in other words I hear/see things turning but I dont have any compression what so ever). If I put my hand on the timing cover when the key is being turned it feels like the chain is just flapping around inside. Since I've already had timing work done to this twice in the last couple of years I'm really hoping this isn't the problem. Not to mention with the guides being worn out and chattering already, I'm not sure if what I'm feeling on the cover is the chain flapping or just vibrations from the chain rattling on the guides, yet the lack of compression leads me to believe that the chain is off at least one of the sprockets. what I'm most concerned about is, if the engine was running fine (except for the misfire) when I shut it off and the chain jumped off either while shutting down or during an attempt at startup, should I be concerned that other damage may have been done (i.e. bent valves like an interference motor)? I should also ask if I'm even looking in the right place or if I should concider replacing the coil housing (since I know they are notorious for going bad), Just seems like too much of a coincidence that it decided it wasn't going to start after taking out the coils to test them out\015 Posted / edited by AnonymousUser on : 21-01-2019

Answers :

You need to strip the engine back to where you can replace the
timing chain or belt ,if necessary & install new guides & tensioners

I think you know all that

Long story short,all your saying is timing related

Repair the mechanicals first

The engine does turn over, as the belts move,
just not the cams,you got it all figured out,you
just need to always insure the mechanical condition
of an engine first & not spend so much time attempting
to test ignition
