My 1991 Ford Aerostar has a 4.0 l V6. It starts fine,

runs great but when started produces a smell. After
running 10 to 15 minutes the check engine light comes on. I have checked some sensors and everything checks O K. I checked the fuel pressure.
with key on the pressure was 44 PSI and when I started the engine it went to 54 PSI. Could this be causing the problem?
