I pour gas in the carb and it will start but not keep running
I just had the transmission replaced and left the salvage yard garage. i went about 15 miles, went to pull in and it cut off. if i pour gas in the carb it will start but only keep running as long as you keep patting the gas quick and short pats. the shade tree mechanic i have says it can only be the fuel pump which is $ 150.00 where i live. he has checked nothing else so far just says trust his knowledge. i am a female of course and on fixed income and have just spent over $ 700.00 for the transmission. is it possible they left something undone? they say it cranked and left the shop so not their problem . please help me !! what is a relay? where is it? about how much is it? what about a fuse? where is it ? about how much? any other wire connection i could possibly check? please if anyone has a suggestion -- i need a way to go ...

Re: i pour gas in the carb and it will start but not keep...
There are several things that can be checked...one of the first and easist is to aslo check for spark while cranking....if there is also no spark .the fuel pump is not the problem...a pikup plate in the distributor...a crank sensor ...a relay ...or a computer can be at fault. have your mechanic check for spark and let me know the results

The head on the motor you bought is bad; or the head gasket is leaking; or the rings in the 2 center pistons are bad. 30 lbs is far too low of a compression, and 5 lbs is garbage. They should be closer to 80 or 90 psi and not have more that 5% variance between the cylinders.
The first thing you will have to do is pull the head off and check it. Or you can take it back to the salvage yard you got it from, show them the results from the compression test and either get another motor, or have them refund your money.
you probably still blew the ECM. my uncle did the same in a full size chevy. it blew the fuse and the ECM. now here is the important part. he went to a salvage yard and they sold him what was suppose to be the right ECM. everything functioned but it would not start. he called me and i found that this was causing so much gas to be pumped that it was pouring in to the oil. he took it back and showed them the old one and then matched it up and all was well.
did you use your old fuel rail and injectors? salvage yard motors tend to get dirt, spider ****, and mud dobber nests in any open line while sitting. check all the electrical plugs on the motor to make sure the injectors are getting power. how long did the vehicle sit not running? could be the pump has rusted and frozen up from sitting.
This truck is fuel injected, the problem sounds like a weak fuelpump, it runs when you pour gas into it until that gas runs out, the first thing is to test the fuel preasure, if the pump is weak it may run with gas poured into it but wont idle, also a common problem is the coolant temp sensor and the ground wires to thermostat housing bolt but i wont bet its the pump inside the fuel tank, if you put a fuel gauge on it there should be at least 55-61 psi if its a few pounds lower it can cause problems, you have everything else and it runs with gas poured so its a fuel problem check the preasure, theres a valve up top on the fuel line to connect a fuel gauge to it, start there hope this is helpful.
Sorry to break this to you.That sounds like a seized engine.When the engine started slowing down,the belt turned slower causing the brakes to almost not be there.Flooring the gas pedal will get you nowhere when an engine is about to seize up.Hot engine will cause steam and a red engine light easily.With a seized engine,pouring gas in the carbeurator won't result in a start either(although it fuel injected).The fuel pump in my Ford(basically same as a Mercury) is on top of the fuel tank which is under the back seat.That was not fun.Feel free to call a couple of shops but I am willing to bet they will say seized motor.If you want to keep the car,I would suggest a used engine from a salvage yard which has fairly low mileage or replecement fully.I have rebuilt engines and the results are usually disappointing.
Once again I am sorry to hear this.I wish you good luck.
Maybe they were right about the column. Sometimes you can go to a Salvage yard and learn about how the parts fit. Then you could see why something needs to be replaced. You can also determine if you can do it yourself or need a garage to do it. Some salvage yards have the parts already out and others you remove yourself.
