Re: Fuel Cut problems at 4500-5k rpms any suggestions

I pulled codes 5 minutes ago and got 23 31 45 and 49. 45 is new as of 2 or 3 days ago. 49 is newer maybe last night? 49 is for wrong air flw sensor so i switched my maf still won't turn on.. Maybe there is fuel in the filter when i blew it out of the cylinders? Ill check my spliced wires i guess too seeing as i recently spliced newer pigtails in. Thanks everyone for you help so far!

Did you swap out the injectors for the same kind or a different kind? It sounds like the injectors weren't seated properly and flooded the cylinders. Hopefully nothing in the engine was damaged since the fuel probably came close or could have hydro locked the motor.

I would verify that timing is still good on the timing belt. You also need to drain the oil and put new oil in once you get the injectors sorted as a bunch of fuel in the oil does not lubricate well and will eventually kill the motor. Check to make sure your oil level is not really high either. If it is you've got a lot of fuel in the sump and should just drain everything before proceeding further.

The injectors are 440cc. I swapped them in about 2 weeks ago. Was trying to swap bask to stock. Flooded.. Then swapped back to 440cc. I drained the oil thrre was fuel in it. Replaced oil, and injector seals that were bad. Now it turns over but car won't start.. Any suggestions? Or do i just sell it. I mean i really need a car

You need fuel, spark, air, and all those things at the right time. Have you confirmed you have spark? Have you reconfirmed the injectors are pulsing properly and the plugs are wet after cranking the engine? I'd also recommend verifying timing as I mentioned before.

You would need to pull the front timing covers off and make sure the timing marks are aligned properly.

Here are scans describing the timing belt process. You would just need to pull the plastic covers off to check. If you found the timing was not correct then you'd need to follow the process/steps in the scans.
