Cracking the throttle a little seemed to make a difference it would crank back up faster tand didn't stall out when I let off the gas. When cranking it for the first time This morning it seemed to cough a little and it threw the check engine light that'* the first time it'* done that. I am going to get me a pressure gauge to check the fuel pressure at this time I'm not sure what the pressure is.

do you have a obd1.5 scanner? know anyone that can get the code? i would get the code then clean the iac and where it seats in the TB and disconnect the battery. its good to know the fuel pressure too.

I doubt the relay. Either they work or don't work. Not when they want to.

I don't have any other problem with the car other than hard to crank after it has been driven a while. It idle fine doesn't stall out nothing electrical all windows and lights work great. And first thing in the morning it will crank immediately but after it has been driven or cranked for 10 minutes it is very hard to restart but even then once it does crank it runs great.

Do you know what the fuel pressure is yet?

It should be as soon as you KO, the pump will turn on for 2 seconds. Then when you start cranking, the pump should come back on.
But if 42psi is what you get either way, your pump is "fine".
So, lets get back to basics. An engine needs 3 things to run. Air, fuel and spark. We know we got air. But is the fuel actually being delivered to the cylinders? Best way to test for spark....hold a wire. No don't do that. Just take a plug out and use the ground method. While its out, check to see if its wet with gas.

I got spark and the engine runs great once it has been cranked up just very hesitant to start after it get hot and is turned off. I think the problem could be with the pump not building pressure until I start turning the engine. I think it should build up to 42 or at least have some pressure with the key on before I ever start turning the car over and for some reason it'* not , it'* almost like it'* losing prime when it'* hot. I will check in the morning when everything is cool and it usually cranks right up and see what the pressure is with the key on but not crunk up.
