Check for a shorted sensor. Try disconnecting the coolant temp sensor, they ussually go bad creating these problems (even when the gauge works fine). Also, you can check ignition timing.

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.

check for spark, no spark, no fire engine wont run, possible bad ignition coil, wire from coil to distributor cap, no power to ignition coil from ignition switch (rare) wire broken to ignition coil (even rarer)

5.7litre TBI won't start. how toknow if fuel pump is working. engine will run when i pour fuel into carb.


If the engines fires up when you pour fuel into the throat of the TBI, then it isn't ignition related

I'd replace the fuel filter (relatively inexpensive) then see what happens.

If it still won't start, check the cranking fuel pump pressure. If no (or low) reading, you may well have a bad fuel pump. Also can check fuel pump relay, to make sure you're getting power to the pump.

Good luck!

Hope this helps and hope someone can help me!

Chevy 454 back fire


Ignition timing is set by the computer as long as the distributor pickup point is within reason.

It could be running too lean. One of the TBI injectors may be sticking or not working (wiring or computer problem), or fuel pressure could be low.

Ran fine then next day all went to /


that sounds correct and its probably electric and in the tank. turn the key to the start position then listen for a small humming noise coming from gas tank if theres no sound then thats most likely the problem.
