I put computer on car came up with code 300 which was a misfire. So I checked makesure I was getting fuel and found the fuel pump was bad. Also replaced the fuel pump and fuel fliter still wont start. I changed all spark plugs because they were really bad and they all were getting spark. Also put in all new coil pack and new camshaft sensor. Still will not start and I replaced about 6 of 8 things on list. It should have started by now. When I turn the key it cranks over and try to start but doesn't.

It could, check your fuel pressure with a gauge 3.1L 41-47 psi 3.8L 48-55psi. You really need to scan for codes as well so try to get power to the aldl and check fuses underhood

I only have a cheap scan tool and I check the fuel by push the thing looks like a tire cap. It shot out like all over the place. All fuse underhood is good except for the ones look like a square. I don't know check the square fuses and thank u for helping me out.

Geta gauge from an auto parts they rent them see if it's to specs. Rescan for codes and if you have an ignition module take that to get it checked. The module is unde the coils
