I have an 88 fiero gt 2.8 and i have replaced the fuel pump, regulator, filter, injectors, the old fuel inside the tank, the ecu, the chip, the head gasket, and the fuel pump relay on this car and it still don't turn on. I have no idea what else it could be. The fuel pump turns on but, if i turn the key forward, back and then farward again, the fuel pump don't turn on again? i checked it and its getting spark too. It will stay on if i spray fuel into the throttle body, so i know that it's cause it's not getting fuel. If you have any advice what so ever let me know cause i need this car to run already!!

Re: engine won't start
all of the battery terminals and cables and check the wires on the
starter/selonoid, start from the battery and follow the cable out and check all
conections , clean and tighten them and if it still does it the
starter/selonoid is bad and needs replacement... also check the ignition switch and ignition module.

Then your fuel pump is not working, or your fuel filter is blocked. You will probably have to check your fuel pump circuit if you have no fuel pressure in the fuel rail, where the injectors sit. There is a fuse for the pump, usually in the under hood fuse/relay block. That is probably also where the fuel pump relay is located. You should hear or feel this relay click when the ignition key is cycled from off to on. Also, when the key is turned to on, you should hear the fuel pump in the gas tank turn on for about 2 seconds. This will put the pressure in the gas in the fuel rail, for starting the engine. If you don't hear the pump turn on for that 2 second period, it is probably a bad fuel pump. But know the fuse is good first.

have a lot problems when i need to start the engine in my genesis 2.0
coupe why is this,,i took the car to the dealer but cant find a
problem,they say battery is ok The national auto parts chains (AutoZone, Pep Boys, and Advance Auto Parts) will hook up a diagnostic tool to your car to perform a Charging System diagnosis for free - its an easy way to exonerate & differentially diagnose your Alternator/Battery/Voltage Regulator.

Your problem may be one of the following: First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side. Next, the fuel pump may be worn out. Usually they get loud or stop working (running). Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side. Is the vacuum line attached? Not leaking or rotted? Also, do you smell a strong fuel odor when it won't start? May be one or more stuck-open injectors, or the coil pack is bad. Checking these in the order listed will more than likely fix your problem. The clicking noise indicates the battery can no longer run the starter, which also means the fuel pump won't run either. It could be a fuel issue. How old is the fuel filter? Can you hear the pump run for a few seconds when you turn the key on? Try turning the key to ON without trying to start engine three times waiting for the pump to stop running each time. Then try to start the engine. If it starts, Its a form of Vapor lock caused by the extreme heat we have had lately, and a weak fuel pump.
If none of this works, try a new fuel filter first. From there have someone check the fuel pressure regulator and then the pump. If you are in need of a new pump, take my word for it and spend the money to get one from a Dealer, and not from your favorite parts store. Most parts store parts are made in China and they are JUNK.
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.
First you need to have your fuel system tested. It sounds as though the relay and pump have gone out. When you turn the ignition to on the pump should energize for 2 seconds and stop. The pump will deliver fuel after startup. Poor performing pump equals poor performing vehicle. With the vehicle not staying running when it did start, I would check the fuel pressure and then replace the pump. You can check the fuel pressure regulator by pulling off the vacuum line and see if you have fuel in the line. If you do the regulator is shot. The fuel pump relay also needs to be checked for operation especially if the fuel pump is not working. Also check your rollover valve to be sure it has not tripped.
fuel pressure regulator? This diverts excess pressure from the rail back to the tank. When they wear out they usually stay stuck open thus diverting all pressure back to the tank. Pressure tests do not reveal this as pressure is checked before the rail not in it. I do believe you have a bad fuel regulator. They are 75US ouch.
