check your fuel pressure and volume. definately sounds like the pump isnt delivering.

You need a gauge to do a fuel pressure test. You can do a fuel volume test with just a 2 liter bottle or something. Find out in the fsm how much fuel should run in what amount of time. Jumper the pump and see the results.

If you can get a fuel pressure gauge. At idle pressure should be approximately 34psi with vacuum hose connected to fpr and 43psi without the vacuum hose connected to fpr.
