If its not air tight then it will be sucking in air there. What about getting a used on from a junk yard like Pull-a-part they sell parts dirt cheap and just transfer your injectors over to it and this is a good time to do a rebuild, O' rings, filter screens on injectors, fuel regulator ect. you do not need to buy a brand new one they are easy to rebuild or swap parts over to a used housing.

Check craigslist for those models listed above to see if anyone is parting out one of those cars or a to locate a local junk man that has alot of car parts listed, may have it never know.

Also idk if u might know but when cold it starts right up but when warmed up it doesn't want to start

Was this before the throttle body got cracked or what led to the discovery it is cracked?

Before it cracked but after the car sat for about two years

Before the crack but after the car sat for two years

I emptied the tank to put in a new fuel pump about a yeAR ago and never got the time to finish getting it fully back up running but now that I have time it's confusing the hell out of me I just refused the tank flushed the lines which led to the throttle body cracking

Ok when warm hard start up, I find likely causes are loose electrical connections, weak battery or starter, improper ignition timing, Fuel filter, a sticky EGR valve, vacuum leaks, Pumps, sensors, ignition parts, cap, rotor, plug wires, plugs, pick up/stator module, fuel injectors, coils. Although not in this order.

Ok I cleaned out the egr when I had everything apart already have changed fuel filter starter is good changed rotor button and cap redid most of the vacuum system what sensors could I be missing when I go to the junk yard in morning I'm going to try to find good wiring I have a couple of wires that need to be replaced

I know it's not the injectors they are new

Cleaning the throttle body may help, as well as Air Temperature Sensor, Air Charge/Manifold Temperature Sensor, Throttle Position Sensor, Coolant Temperature Sensor, EGR Valve Position Sensor (not Valve), Barometric Pressure Sensor, Crankshaft Position/Angle Sensor & MAF and O2 sensors. Replace the fuel pressure regulator when doing the throttle body this could very well be the issue. There is a test fro EGR valve too. Ignition Pickup/Stator when they go bad most times it will run when cold and will not when warm but with any electrical part it could go bad in a various ways may be worth changing it out. There is some test for almost any sensor with a voltmeter online that would be a good idea to look up some. There is a spring and gasket in the fuel regulator that may when hot not function well or sip out fuel if bad gasket or loose pressure that way too and spring could be bad from being in the same position for a few years along with the crack in casing may be all that is wrong. I would fix those wires too. Check or replace plug & plug wires and use dielectric grease on boots to prevent aching.

Where would the pick up stator be located I don't think this car has temp sensor no gauge on dash and has clutch fan

Gonna see what I can find in junk yard might be able to locate everything for throttle body in better condition then what I have

This answer is likely to late if you left for the junk yard but pick up stator is in the distributor. It just does not have a gauge on the dash.
