Not sure if they moved the FPR on the '89 2.9, but on my '87, the FPR is at the rear of the fuel rail. 1st check for a bad FPR is to pull the vacuum line (after running the engine) to the FPR and see if there is gas in there. Gas = bad FPR. 2nd step is to put a fuel pressure guage on the fuel rail and see what the pressure is.
