I just replace the fuel pump,filter and carburator on my 1983 plymouth reliant it will turn over and start but wont stay started
SOURCE: 1983 chevy 454 wont stay running
If it's an electrical problem it wont start at all. If it starts, runs or a few, it's a fuel issue.
A new pump and lines, what about any inline fuel filters and the fuel filter in the carb fuel inlet? If it has a quadrajet carb, the fuel inlet filter will play with you.Check your idle speed and the auto choke setting.Any questions on how to balance the carb and set the xhoke, Feel free to ask. _NNed

Check to see if you are getting the correct fuel pressure at the rail. It takes at least 55psi to push past the propets in the spider assembly. Cold weather requires even more psi. You can test this with a cheap fuel pressure gauge from almost any auto part store.
I would also check to make sure the ground for your pump has a good connection, it should be located around your rear bumper in the center. A weak ground will dramatically kill your psi, but still push fuel to the rails.
There is also a problem with the "expensive" spider assembly of that truck. The spider assembly holds the single injector and has 6 tubes going to each cylinder. The lines going into the assembly are known to leak. If you take off the manifold you can easily see if there are any leaks from it, there will be wash marks where the gas has cleaned it. Instead of buying a new spider assembly, there are rebuild kits for it.
If for come to the conclusion that you need a new fuel pressure regulator, don't let them lie to you in saying you need to buy the whole spider assembly. You CAN buy it separately for around $40. If you have problems finding it at local stores, search for it online.

sounds alot the the pcm it controls the fuel pump and ign system but the anti theft would keep it from starting because the key has a transponder in it programmed for that vehicle and that would kill all ign if triggered
