1993 2.4 4cyl. pickup starts but dies, replaced fuel pump and filter, has fuel inj.


spray some carb cleaner into the throttle body intake, i bet when you take the air feed hose off the top that it is gunked up, this needs to be clean at all times, really spray it everywhere inside the throttle body & turn the "Butterfly" over & pray both sides of it, then start your car, if it continues to die then it most likelt is a problem with the O2 sensors.

1998 gmc savanna only runs for 2 seconds unless i spray either in the throttle body than it runs longer


Gm vehicles are known for failing antitheft systems. One of the symptoms of this failed system is that the vehicle will start for 1-5 seconds and then cut the power to the fuel injectors and stall. This is the antitheft prevention. It's purpose is to keep people from "hotwiring" the vehicle" Normally this will be followed by a light on the dash or gauges that says SECURITY or ANTITHEFT. if you see this light, it is pretty much a dead give away of the problems. But since the security system controls the light itself, it may not always be present. This link explains the problem and offers solutions. Just a thought, hope you get it all figured out.

Mycadillac wont crank


These cars are equipped with an antitheft system that disables the starter if not working correctly or attempted theft. Turn your key forward 2 clicks until right before it would normally start, if you see a light in the dash that says SECURITY or ANTITHEFT, go to this link for help.

How to check if the antitheft is bad, the engine turns has power, pressure to the fuel rail is good. Injectors good but no power going to them when cranking. Noticed the theft light stays on when turning...


in the center of the dash you have a flashing red light when car is not on looks like alarm system. if that light is flashing or stayting red while cranking you have a antitheft problem

I install a fuel pump but can't get any fuel to the throttle body. the fuel pump runs but it won't go through the throttle body?


hi.. so is it a carby or direct inj or throtle body inj ? if its a carby then you may need to clean out the jets, if not then the fuel does not neciserily go through the throttle body, just make sure your fuel lines are on the correct way, they are easy to confuse and usualy the most common mistake... if it is a mechanical fuel pump to a carby try starting useing 'easy start' aerosol can and it might help **** the fuel through... also if the carby is empty it will be hard to get fuel in so you can help by tipping some fuel into the carby pots..

Crank no start: has no spark and only has injector pulse on cyl # 1. if you spray starting fluid directly into throttle body car starts and stays running and has spark and inj. pulse. once you turn the car...


Fuel pump, you have to have press in the rail to fire all injectors- she will run on ether but not good for her. Ck your pump and any related fuses,relays,wiring.

1988 gmc k1500 wont start


hi, check the connections at the ecm,i think it's under pass front seat,i've had a couple of those years loose injector signal at ecm connector,if you have a test light you can unplug injectors and test across terminals ,it's a 12v signal at inj ,if lights flash on both while cranking try plugging in one at a time and see if either sprays, if one does and not the other, you would have a shorted injector
