Just recently I started having a problem starting my 97 EX that has 190,000 miles on it. The problem is that when I try to start the car the first time it will die (both cold and hot). I turn the key off and do the restart procedure again. Usually, this time the car starts. If it doesn't start, I do the restart procedure again and then it starts. After it starts the engine run flawlessly and nothing else seems to be a problem. I suspected it to be a fuel pressure problem and that the fuel pressure regulator was defective. However, after checking the fuel pressure with the engine running it was a nominal 43 psi with the vacuum line disconnected and plugged. When I reconnected the vacuum line the pressure dropped to a nominal 33 psi just as the manual requires. I have no error codes showing from the ECM. Now that everything checks out, I don't know where to look next. Has any one else had this problem and what was the cause and correction?

 

try reseting your ECM by disconnecting the negitive cable for 45 seconds then hook up and start again.
