Sits inside the throttle body, you would have to open to install regulator. Also check your fuel filter make sure it's not clog, fuel filter is under truck on fram rail, while your there do a fuel pressure test, with a fuel pressure tester, should have 13psi.

No, low fuel pressure is caused by a weak fuel pump.
High fuel pressure is caused by a faulty fuel regulator.

Removel of injectors 1991 chevy 350 c.i. pick up


This repair is not that bad. ***NOTE: don't disassemble the TBI unit until you have purchased a new TBI gasket. The gasket is paper and when you remove the screws and pull the top half away, the gasket will tear.*** Remove the air cleaner housing and you will see the T.B.I. unit. Unplug both injectors, remove the torque head screws, and carefully pull the top have of the injector housing away. You now can remove the injectors. Just in case you don't know. If the fuel pressure regulator is original, this would be the time to replace it. I hope this helps, let me know how it went.

87 chevy 350 tbi will only start if if pour gas in the throddle body then keep it running by pumping the peddle. It seems to starve at higher rpms, and when it does idle the rpm's swing from hig


Sounds like the fuel pump is going bad(or in this case,has gone bad). I suggest that you change the fuel pump and use a fuel cleaner in your gas tank as dirty gas may have caused the problem to begin with.

1995 chevy silverado 350 TBI V8 standard powerloss


have you checked the filter, i know you state the fuel lines are clear though. likely fuel injectors have lost flow. the TBI injectors can be cleaned, but i usually just replace them. but check them using a timing light hooked to the coil wire for timing of each injector spray. the pattern under the light should be even and conical shape, no major spatter. if one shows low volume, the other one should be replaced at same time, it will save you having to change it when you put brand new next to old one a have same problem again. only replace with brand new, i've had 7 bad remanufactured injectors on one truck at one point in time, only replace with new!

1988 5.7 TBI Nightmare This is the start of what the problem was and is, I had a RV cam installed when the engine was rebuilt a year ago. the cam was not a computer friendly cam so after a round with the rebuilder and discovering the specs weren't the correct ones for the cam I installed a 3702 edelbrock cam and lifters with a 7800 timing chain and gear set after I had tried two chips from Jet and no improved performance and the 3rd chip was to be for the cam and that is what is in the ECU now and I have tried about 5 different BCC chips and the bottom line is the power is there but something is happening its hit and miss the idle will sometimes lope, is stalled when first started and acts as if its starving for fuel or its bogged with to much fuel. the fuel pressure is 10 - 13 psi and I have R/R the TPS, IAC, ESC and knocks device , EGR and Solenoid, MAP, Temp sensor, and the Dist is a Procomp 10001 with a MSD-5526 coil. the Throttle Body was rebuild and the ECM was replaced with a Rebuilt ECM. it will smell rich etc. but with the things that goes on it does not show any codes?? I have no clue just feel stupid this is been a simple thing that is kicking my **** and now its a challenge but still loosing the fight too far in and too much spent to stop,. LOL Help !!!! The BCC is a california vehicle AFBX, 5.7TBI TH400 A/T P.S. the key can be turned of and back on as the engine not dying and seems to correct the power and run problems but will not last goes back to running bad or with problems. ?
