The long crank time makes it sound like fuel pressure is leaking down. Also, the fuel smell after its running would make me believe theres too much fuel in the cylinders. Everything here points to the injectors leaking internally.

Swap the whole coil pack assembly or just the ignition module. I’ve been through this before with quad 4s as I’ve swapped many of them between my brothers GTZ and my friends GTZ. They were blowing engines every couple months. Theres a difference between the ignition modules. Anytime I swapped a chevy quad for a pontiac quad, I had to change the module. It could be a difference in the year, but I’ve always had to do it before it would fire up. Good luck.

Theres a good chance that your lower intake manifold gaskets are leaking causing a loss of coolant. These engines are notorious for that. As far as not having heat, it sounds like you have air in the cooling system. The bleeder is located above the waterpump on a black pipe. It takes a 7mm wrench or socket to loosen. Make sure when you tighten it back down you don’t crank on it or it will break very easily. Just snug it up, it won’t leak.

Your intake gasket does look bad, but I’ve seen much worse. The slightest deformation would make a leak. Quite honestly, it isn’t much more work to pull the heads and replace the gaskets. The parts are cheap as well. If you decide to go that route, replace the head bolts as well…..they’re only like $25 for a set for this engine. Don’t forget, the push rods are different lengths, so you may want to keep them in order, but if memory serves me the exhaust valves take the longer push rods.

[quote=”SamG.” post=45680]Have you tried a wet test? You may have the cylinder wash. The ecotc isn’t interference but depending on how the car was driving when the chain broke it could of done some serious damage.[/quote]
I have a bucket of bent valves from a 04 Ecotec that would prove otherwise.

If you have an Ecotec 2.2, you have bent valves. A common problem with these engines are failing timing chain tensioners. Good luck.
