You will need to put a fuel pressure gauge on the line going to the carb. Running, you should read about 5-7psi. If you don't have a gauge, disconnect the line to the carb and put a length of hose on the end, place other in in a gallon container and start the car...you should have at least 1/2 gallon of fuel in the container when engine stalls. I am fairly certain that there is a filter right inside the carb fuel inlet. Make sure the filter is clean. If after testing, you find that either you have bad pressure or delivery from the pump, replace the pump. Also make sure that all undercar lines are not leaking...even a pin hole in a line will cause the pump to draw in air instead of fuel. Blow air back through the line to make sure there are no leaks and that the tank "sock" filter is clear. good luck

It gets gas through the lines but wont turn over, put gas in carb. and it starts but wont run very long


Have you replaced the fuel filter resently its under the drivers side door mounted to the frame this may solve your problem and its a good place to start but this may vary well be a problem with your fuel pump its around the time when you would start to have problems with it 10 to 12 years with these pumps is about it for them depending on your usage and milage good luck.

I have a 88 Fiero GT V6 that has sat for over a year without starting. I put in 5 gallons of gas, and used starting fluid. Starts, but only keeps running while fuel is poured into intake. I suspect water...


1) Running fuel pump to remove water from tank will likely not empty it all, but it might help. Will still be some liquid in bottom of tank.

2) More than likely, the gas has gummed up and is no good, While your draining of the tank will help, may still need to change the fuel filter and clean the injectors. The ability to keep engine running while pouring into the intake is a good sign, but mayfind that more parts need to be cleaned and replaced prior to solving the problem.

88 fiero starts on it own, but wont stay running.


the brain is not sending the proper fuel pressure codes to the fuel rail to evenly distribute the fuel to the intake and fuel rail.
perform a fuel pressure test check on it ok? also run a diagnostic scan on it and see what codes come out.

Same exact problem


Check your pump, fuel filter and lines. Most likely If stored one of these three items has a problem.

Too much fuel pumped into the carb. What to do?...adjust?...set?


The idle air control valve may be at fault, also the throttle position sensor may be telling the engine th wrong information and sending too much fuel, a couple other ideas come to mind but I not an expert. A faulty injector is one of them.....I another idea that may help as well: Vacuum Leak: The ECM will try to compensate for leaks up to a certain size. This will cause the ECM to compensate and possible send too much fuel to the engine...???? Good Luck
