That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.

Is the injector sprayin? have someone look while you turn the motor over, if it is it may be that the injector is sprayin to much fuel and flooding the engine,or the TBI is sucking air, theres a gasket the connects the top and bottom of the TBI that could be bad. my truck is doing the same thing, the only way it will run is if i hold the pedal to the floor to get more air inside the chamber, if i let off it chokes down and dies.

( does anyone know where i can find a 2barrel carb and intake to put on my 2.5l, i want to get rid of the TBI system)

92 Camero SOMETIMES wont start, backfires or starts rough - but will run fine after it DOES start


I would want to know if it is ignition or fuel for sure. There are a few things you can try to narrow down the possible cause.
What does the cap and rotor look like, and is the spark a strong blue when it is running rough ?
Have you checked the actual fuel pressure with a gauge ? Does it matter if you spray carb cleaner or starting fluid into the throttle body ?
Any trouble codes stored in the computer ?
Its possible the coolant temp sensor is wrong and the computer thinks the air temp is 90 degrees instead of say 20 degrees. Or there is moisture in the dist cap or on the plug wires, and so on.

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.

Wont idle or start without priming tbi


first check fuel pressure with a mechanical fuel gauge that attaches to fuel line schrader valve. around T.B.I. if no pressure with key on check fuel pump relay for correct operation, and also the oil pressure switch has the fuel circuit to it so possible oil pressure switch also. fuel pump has a check valve to keep fuel from going back to tank, so when u turn key on fuel pressure should go up within 1-2 seconds on gauge. if fuel pressure goes down quickly, possible bad fuel check valve, change fuel pump and fuel pump check valve (located right above fuel pump inside tank)

Will turn over but not start put a new fuel pump in it if you poor gas in to the throttle body it will start for a min until gas runs out


I had the same problem with my old 1987 Chevy blazer s10. The problem was the ground wire of the fuel tank was rusty and it broke. So simple was the problem. But before that, I checked and change the fuses, the fuel filter, the oil pressure switch (this is related to the fuel pump to) and finely when a was ganging the fuel pump saw that the ground wire was broken or damage.


I hope this can help you.

I have a 90 chevy k1500 350 tbi with same problem! I have traced problem to... after turning on key fuel pump kicks on when u crank it over injectors shoot gas and truck starts! After few seconds injectors stop spraying and truck dies! This can happen many times over and over! Eventually sometimes truck stays running and all is great! I changed ignition module, oil pressure sending unit (which i was told controls gas after vehicle is running) fuel filter, computer, fuel pump relay, I am at a loss now! Hope this helps and hope someone can help me!

Check the injector for 12v on one wire. if good check the other wire for a ground witth the key on. The ground wire pulses from the ECM If you dont have 12v from one wire to the other but you have 12v from one wire to battery ground then be sure the ground wire is good to the computer. If you don't have 12 v at any time check for open hot wire or bad fuse. ADD 12v to the hot wire at the injector. DO NOT add to the wrong wire or you will fry the computer
