All of the sudden my 91' RS Camaro convertible, stopped running. I did put in sea foam about two weeks ago to clean out system. Now, she will not accelerate at all. The only way to keep it started is to pump gas pedal vigorously when first started, then still dies. I am not even able to get a reading on fuel pressure gauge cause it will not idle. Will only idle for a second or two, literally .
Can someone assist me? No codes, have already changed fuel filter, MAP sensor. I have already put seafoam throughout the fuel and vacuum lines. I took apart the throttle body TPI up to the inlet and discharge fuel lines. I did not break down the 2 fuel injectors (plastic piece w/electric wires over two prongs x 2). Cleaned well with cleaner. When broken down, I turned over motor and fuel spewed out of inlet line significantly (fuel pump works right)?. Put TPI back together and did not see fuel dripping or misting from those so called injectors. What next? Please

From reading this it sounds like a fuel pump issue. I believe TPI and TBI work the same just different pressure. The car does not have to run to show fuel pressure if you have an electric in tank pump. If you hook up a FPG and turn the ignition on but don't start, your fuel pump comes on and pressurizes the system for starting. Your gauge should read between 8-15lbs for TBI. If this is not happening there is either a relay or pump issue. If you pull the line and gas comes out it sounds like the pump is week and won't build pressure. Start here and recheck you fuel pressure.

Sounds like you are talking about a TBI.... I too am leaning towards fuel pump issues. Not being able to make pressure with Key On/Engine Off is a sign of a leak or bad pump.
