Why will my 1988 chev truck not strat when its getting too the throttle body. But will run when your pouring gass in the throttle body.

Check fuel injector fuses. With the key one you should have power to the injector plug. You could have (gas) fouled out spark plugs. Or timing jumped.

check your fuel flow and pressure.
check that your injector(s) aren't clogged
check your map or maf sensor

Hello, just had this problem myself. Check your EGR valve by pulling the vacume line off and pushing up under the valve put your finger over the vacume line hole and release the valve, if it returns to normal position then its bad if not its good. If its bad it needs replaced. Mine did the exact same thing and thats what it was. Hope this helps

I had one with the coolant temp sensor telling the ECU is was -40 in July. Replaced the sensor, was fine after.

check the vacumn pipe that runs to the end of the injector rail ,their is a vacumn operated valve that if the pipe is perished it will never go as it will not allow petrol in

check and see if your air inlet tube has a crack or hole in it between the throttle body and the mass air flow sensor

Try a new fuel filter. If that doesn't help, check the fuel pressure--may be a plugged intake sock filter inside the fuel tank.

it sounds like the injectors are not opening up man.. replace the injectores and this should fix your problem..good luck keith....

no timing belt on the particular vehicle. but yes probably something minor, check fuel pressure, fuel pressure regulator, MAF sensor and IAC motor. all these can cause intermitent stalls. The MAF is located somewhere between the air filter and the throttle body. it is a sensor that sometimes gets dirty with air particles and will affect fuel managment. the IAC motor is on the throttle body and if gets stuck with carbon will not be able to control idle. the fuel pressure regulator is on the fuel rail and if the vacuum line is filled with gas then the diaphram is bad. and the fuel pressure should be 35 to 50 PSI running.

Hello thank you for using FixYa.com for your answer my name is David.
You say it wont start in the normal way by just turning it on but if you pour gas in the throttle body
it will start sounds like you have a weak fuel pump most likely but there are a few other things that could cause it also .

1 Inspect Battery Damaged or faulty battery and/or connections. 2 Inspect Coil - Ignition Damaged or faulty ignition coil or ignition coil circuit. 3 Inspect Fuel Filter Clogged or dirty fuel filter 4 Inspect Fuel Injector Pressure Regulator Faulty fuel injector pressure regulator or circuit. 5 Inspect Fuel Pump Improperly functioning fuel pump or circuits. 6 Inspect Wireset Damaged, worn, or deteriorating spark plug or coil wire(s). 7 Inspect Control Module-Ignition Faulty ignition control module or circuit. 8 Inspect Solenoid Switch Damaged or faulty solenoid switch or solenoid switch circuit. 9 Inspect Starter Damaged, worn, defective, or faulty starter or starter related circuit. 10 Inspect Neutral Safety Switch Damaged or faulty neutral safety swittch or circuit. 11 Inspect Air Charge Sensor Damaged or faulty air charge sensor or air charge sensor circuit. 12 Inspect Fuse Corroded, burned, or shorted fuse may be interupting power source.
