I have a 85 coupe,the pumps are notorous for going out.Best bet is empty the whole tank.the pump .Is easy to pull its under the filler door.1 make sure its not your security system shutting off
your injectors .2 turn key in on poss and open gas door you should hear the motor.If not
disconnect batt and remove.be car e you dont lose the screen.once out dry off and hook up to any batt to check.there only 30 bucks but make sure you ground it out right and dont turn it on in a dry tank ,you will burn it out.

Your car is tuned port fuel inj. so your problem probably lies in the throttle body, or the oxygen sensor in the exhaust that tells the intake to allow or disallow the passing of air depending on how rich or lean your car is running. Hence the reason fuel injected cars wont start if you put the pedal to the floor. If the O2 sensor is bad; your check engine light will show.

1985 corvette cranks but won't start, fuel pressure good, oil is good also, it doesn't seem to be geeting any fuel. New fuel pump, filter & gas. Is there a security aystem problem?


Check to see if you have spark, if you do, and still it does not start, then you may think that fuel is not getting to it. At this point, use some starting fluid and spray it at the throttle opening. That should start it for a few seconds and give you the answer.

1989 corvette, replaced mass airflow and still cuts out and then runs rough till it sits for a while. Took it to chevy dealer and mech said that another sensor was causing problem with the mass airflow...


on the back of the throttle butterfly is a sensor that controls the amount of fuel and it has carbon paths inside it ands i think this is the one causing your problem ,

1985 corvette wont start


NEVER use either!! EVER! It burns very dry and can destroy a gas engine! Just give it a bit of gas down the intake.But keep the can away after each try! Far away! Not sure how you are getting 32v?? That can't be volts! Silly question, but is there fuel in the tank?? Have seen this before! It would be great to learn how this all started?? [or should i say stopped] lol Check the fuel line for a pin hole. It sounds like it is sucking air. Really need a bit more info. OK Frankster016
