fuel pressure 200 1989

posted by  someone claiming to be Tony on  Tue Nov 28 06:22 CST 2000 [RELATED]

Can anyone tell me besides the fuel pressure regulator what else would have an effect on the fuel pressure? The problem started with a little problem starting the car first thing in the morning. Then it went to when you pulled out of the driveway I had bad acceleration until it warmed up. So I had a mechanic friend check the fuel pressure and it was low so I changed the regulator and it help the starting problem but the bad acceleration is still there. I've cleaned the brether system and had the fuel injectors checked all good. Any suggestions? When it warms up everything is fine.

    Replace your fuel and air filters, then check your O2 sensor (700/900 FAQ has procedure). A bad O2 sensor will cause a myriad of drivabilty issues.

    Fuel filter??

    You have that 'sock' on the in tank pump which may get all gummed up depending on how good the gas station is. I have an '89 with 186000 on it and the tank sock was beautiful when I did the in tank pump a few weeks ago. BUT you also have the biggy under the car (under the drivers seat). That will definitely cause a restriction. I think they recommend changing it every 30K.

    If you are in an area that goes to this Oxegenated fuel thru the winter, I hear that this fuel pulls all the crap off the gas stations tanks as well as your own gas tank and clogs fuel filters. My friend says most of his winter quick fixes are just new fuel filters (he owns his own service station).
