I know it is on the right stroke and everything I even tried the other, but like if I give it WOT then tried to start it and then stop and drop it to 25% gas it like goes put put put put. And it I don’t give it any gas or just leave it at WOT it just goes put, So……. IM stumped… I don’t know what to do know.. I checked to see if all the spark plugs are in the right order. I checked to c if they are getting spark. And it all checks out…



Have you checked the fuel pump and to see if you're getting fuel in the cylinders?
I mean, recently - after you cleaned out all of the fuel from before?

FYI most factory ECU's will cut fuel when the tps reads 100% (ie floored). This is a way to tell the ECU it's flooded and to stop injecting fuel while cranking.

I just went back out there and checked all the fuel injectors and they are all fringing ( I did the screw driver with the long handle and put my ear up to it and listen to a clicking sound)

Well, maybe I have bad fuel injectors…. Would they still click even tho there is no gas flowing through them… And I tried to take them out.. and I can not get the 3 bolts out.. that hold the bracket on. I searched but didn’t find anything on showing how to remove the fuel injectors but I might have missed. Ive read that they are Easy but.. the 3 screws that hold the rail on… I cant get a socket on them, and so I put a wrench on them. But I don’t want to strip the little suckers, I tried putting WD-40, Parts cleaning and all this other stuff… and nothing…

check the fuel pump first. put a paper clip between FP and +B in the check connector. Turn key to ON but do not start the car. You should hear the pump running and fluid flowing in the engine bay as fuel recirculates back to the tank.
You can check the fuel injectors by putting in dry plugs and cranking it over a few times - some of the plugs should become wet with fuel.

Aright I connected the FP (fuel pump) to the B+ (Battery positive terminal) yesterday and I forgot to tell you, But yes I could here it flowing. And The spark plugs come out wet. Sorry I should of told you that yesterday….


Edit: So, it is getting spark, gas and all the timing is correct, How do o check to c if it is getting air….

Its called an AFM, not MAF

Yes, I am getting spark in all the cylinders like I already specified. All my fuses are good. And yes the AFM is plugged in : ) Today I took off my fuel rail and fuel injectors and cleaned them all. And still.. no gooo! WHAT ELSE COULD IT BE!!!
