I have a 96 Integra SE. I try to start it in the morning and it cranks and cranks and cranks not firing. I can hear the fuel pump and no check engine light. After about 3 or 4 cycles of cranking and resting it will crank then as soon as I let the key go to give it a rest again it fires and runs fine. then every time after that it fires fine. Even after 8 hours at work i get in it and it will fire right up. only after sitting a long time, like overnight it messes up like this. I have tried looking for this problem in SEARCH but couldn't find anything like it. I am new so i might be doing it wrong.

where do you park overnight? on the beach? in a cave?

even though you hear the fuel pump it could be having trouble delivering the fuel. do you have a fuel pressure gauge? you could add one of those to see if fuel pressure is the issue.

I park on a concrete driveway overnight. Also i will try the fuel pressure but it is a wahlbro 255 pump and it is fairly new. It seems like and electrical problem but any info is appreciated.

i was asking where because of moisture. if i go on a vacation and park 100 yards from the ocean for a week my car will have trouble starting after sitting over night because of the humidity.

I added a fuel pressure guage the other day and it goes up to around 41psi when i turn the key forward then when the fuel pump kicks off is goes back to 0psi when i'm cranking it to start it stays at 41psi then when it finally fires it idles around 41 and under full throttle it goes up about 5 psi. so there we are. PLEASE HELP!!! this is very anoying.

your fuel pressure is fine. you might have dirty fuel injectors. tell me more about your car. have you done any work on it?

another idea could be your coolant temperature sensor. read this:

there's some debate, but a bad sensor may cause the fuel mixture to be too rich.

The work i have done to the car is this: It was turbo'd with a hondata computer. Ran ok but was difficult to start, but had a good tune in it ran around 10 psi. A capassitor blew in the computer. I bought a new socketed ecu and transfered my hondata s300 into this ecu. Car still hard to start and won't rev out, When it got into the boost it would fall on its face, i could never floor it. It had r/c 550 injectors on it. I then got fed up and took the turbo off, put stock injectors and ecu in the car. Now it takes forever to start, but when it does it runs great and revs out good.
