88 e 150 problems
i have an 88 e 150 w/351 f inj.i have been trying to get sorted out..i have replaced all 3 fuel pumps,filter,tank transfer valve,rewired the pupms to run off a toggle switch ,rewired most of the wire plug connectors on the van because of corroded terminals, and still the van will not run properly.every indication led me to believe i had a fuel problem but im not so sure anymore.i have it seems good pressure (35) psi at the rail so id assume im good on pressure.but as you go down the road it just acts as its starving for gas but not all the time.but it could be a spark problem or something else i just dont know.when sitting still i put it to the wood and it acts as though it got a rev limiter set at about 2500 rpm any input ?????????????????????????????????????????????????? ?????????????????????????????????????????????????? ????????????????????????

you didn't mention your fuel pressure regulator. check to make sure that it has a good vacuum connection and that the regulator is in good shape. it sounds to me like it is fully opening so that you lose pressure once the vacuum starts to drop off as the throttle opens.
