It sometimes primes but not always,, so most of the time my car wont start after sitting for a day because pressure isn't built up.. Power is always getting there but just wont prime sometimes, is there like a pressure sensor somewhere to detect fuel pressure?

 

anyone at all?

 

I'm willing to bet with it being summer time.. it's your PGM-FI main relay..

It's located near where the hood release latch is.. there is one or two 10mm bolts holding it in and a wiring harness..

It's a Grey box with some writing on it..

During summer time the joints on the board get hot and crack causing bad contact which results in your fuel pump not priming..

Next time your car doesn't start tap on the relay while trying to turn the key on and i bet the fuel pump will work..

If you want to fix the problem.. pull the relay out and pull the cover off.. and get a soldering gun and reheat the joints and it will be good as new.
