TX 88 fc not starting.

ok forgive me plz for not being on here for so long. crap always roll down hill. so since i got the car i had to get a new battery (basic 715 cca) and had to readjust the tb and put a new starter on it. it will start when cold with out a prob, she doesn't like to idle but she dose start. when the car is warm, like running to the store or so and i turn it off it doesn't want to start for almost 1.5 hrs, now iv replace fuel filter cuz i have to premix due to my lack of funds to put the oil injectors back on to my understanding it already has a emissions deletion. im my wife left and took everything but my car so im starting from squire one but i need it to be more relayable to start. out side air dosent seem to have an effect on starting. have spark, got fuel psi, injectors test good, battery and starter pass. when i get it running or when it wants to start it runs great no probs there. i need help bad idk if this is a data issue mechanical issue or just a bad part i.e. battery. i now live in gainesville tx id pay for real help. plz!

If it won't start hot it coukd be injectors leaking, compression low among many factors, compression check is easy and cheap to perform

going to go get a compression tester. ex even took my repair manual. what is the compression magic number? iv pulled plugs when i first noticed this prob and they are dry, i can sometimes get it started if i hold the throttle wide open if i don't it doesn't even sound like its hitting. when i do she sounds like shes trying to start but just not spinning fast enough.

ok used this link i found in a old thread, http://rotaryresurrection.com/2ndgen...ion_check.html now following all instuctions im getting 35 psi for each rotor face on both rotors. however on the 2nd rotor im getting an over all compression of 60 psi and 70 psi on the front rotor. not it dose worn that a week battery could resalts in low compression test, now could the battery not be spinning the starter fast enough to start the engine when its warm or could the starter be drawing to much juice from the battery when its warm? note i only have this prob when the engine has been running long enough to warm up, i have had the battery and the starter tested at o'reilly. and they told me both were good. what do you guys think?

We just had this same starting issue with a 10AE with less than 10k on this fresh motor.

I have a switch that I throw when my car is warm and wont start. It cuts the fuel pump off. Then I crank the car and it starts then I throw the switch back to turn the pump back on. This is a cheap solution to the hot start problem and works everytime. My compression if a little low as well 60-70 and 77-85 on other one, but still runs very well. I don't worrry about getting stuck now with this solution.
