84 crossfire - Injectors delay 1-4 seconds before spraying

[showman]

Sometimes, more lately, it'll take a bunch of cranks before the engine starts. Saw that the injectors would drip 1-4 seconds, then spray.

Car is also intermittently running rough. Replaced filter, okay fuel pump pressure, found no leaks.

Thanks!

You may have a bad fuel pressure regulator, causing the fuel to leak back into the tank. X-fires dont hold alot of fuel pressure, but if its a bad regulator or check valve (in the fuel pump), it'll cause the problem your describing. You need to get a fuel press. gauge hooked up, the pressure should slowly bleed down, not immediately though. Running press. should be 9-13 psi.
