1990 ranger 2.3l l4 won't start will crank
Ok I have a 1990 ranger 2.3l that I have inherited from my great grandfather but it was parked for some time I don't want to scrap it but I'm 1.4k deep and it still won't run it has a complete new fuel system, new spark plugs and wires, crankshaft sensor, Ignition module, and it won't start
I have been able to start it for like 30s but it shakes and then dies and will not take throttle at all
Any advice?

Welcome to FTE.
Lets think about this some more, lots of unknowns, but reading as how it'll crank, start, run for half a minute but poorly, with no throttle response, have a look at the TPS sensor resistance, fuel pressure & make sure you don't have the plug wires crossed & their insulation isn't damaged from varmints chewing on them. Perform a fuel pressure & timing test & post the Numbers.
EDIT: Also remove the engine Air Filter & make sure a varmint hasn't made a nest in there that's choking off air flow to the engine!!!
Scan for trouble code clues & post All code numbers, as they can help focus a trouble shoot. It's OBD-1 so you don't need a scan-tool, or code reader to extract pending, or set trouble code clues, by following one of these test set-ups that seem best for you. We can also series in a 12 volt buzzer with the analog meter, or LED, to also Hear as well as see the codes being winked, Ford OBD/OBD2 Codes – TroubleCodes.net
Since we don't know how long its been setting & under what conditions, has the old fuel been removed from the tank, new fuel & filter added & again was a fuel pressure test performed Before trying to start this puppy???
Also, seeing as how its OBD-1 diagnostics, have a look at the info on this site Ford Fuel Injection » Home (archive.org) about values on various systems sensors you can make with your multimeter in making sure engine air, fuel & temp sensors are reading ok & not sending the ECM corrupt data. This info has been helpful to me in keeping my 94 Taurus happily on the road through the years.
More thoughts for consideration, let us know what you find & how the resurrection goes!!!

One thing that may cause a 'start - immediate stall' is the MAP sensor if equipped. It should indicate with a DTC that it is failing. If you can get a EEC-IV code reader or attach a VOM to the leads and connect the jumper, you can parse the codes stored.
Of course, checking for spark while cranking and squirting fuel into the intake and then attempting to start should give a hint as to the cause.
