Check fuel pressure at idle and when you place the gear shift in drive. (Jack up the front wheels and block the rears) The pressure should be between 39-45 psi at idle and not drop more than 5 psi in gear. If it does, check for a clogged fuel filter first then remeasure. If the same problem, check fuel pressure regulator. You may have a leak. Pull the vacuum hose and check/smell/feel for gas. If there's any, replace it. Also, when remeasuring fuel pressure, pull off the vacuum hose while the engine is running. The pressure should increase. If it doesn't, replace the FPR.
If both the filter and FPR check out good or are replaced, next check the fuel pump.
