You don't have a carburetor, The fuel injection needs a lot of pressure unless it's a TBI system so check the fuel pressure. Something about this sounds a bit wacky so keep me posted right here. I think the fuel pressure for TBI is 9-14 lbs for EFI its 45-60 lbs look these up if you can my memory is good but you never know. I hope this helps you, take care
