Sometimes the engine will not start right away. I have tried turning the key off about 5 seconds then on for 5 seconds before turning to start. That did not help. I have tried two, three, four cycles without it starting. I have had it to the dealer twice and no codes show. They ran EEC test P1507 ran PIDS replac IAC reprogram PCM and performed fuel system treatment service. I have had it to other mechanics but it never fails to start right away then. It may go several days without problem, then it may happen two or three times in one day. I don't know what to do next, but I am afraid it might fail to start completely. Once started it idles smooth and runs fine.

Hi:
The P1507 is for the IAC which you had replaced. You mentioned they checked the EEC. Did they replace the relay? Also, when it doesn't start, do you hear the fuel pump turn on for a second when you first turn the key?

Let me know.

The only thing that was replaced was the IAC. I have not been able to determine if the fuel pump starts when the key is turned on. I have tried to borrow or rent a kit to test the fuel pressure, but I have not found one. They are priced $45-$380 at the parts supply. My car does not have a test port, so it would have to be teed into the fuel line.

Yes, I checked at Advance, Autozone, Napa, O'Rielly's, and CarQuest. They only had fuel pressure test kits for sale. They didn't think the fuel pump was the problem since the car runs well after starting. At high speed, acceleration, and going up hills there is no problem. Any suggestions.

I understand their logic and agree with them. My concern isn't so much that the pump isn't working properly, but rather it is losing its prime and making it hard to start until the pressure is built again. You could have a leak, leaking injector, bad check valve in the fuel pump.

It's a starting point for me. If that can't be checked, the only thing I can say is check to make sure you are getting a. Wait. I have an idea.

Rather than checking pump pressure, when it is cold, see if it starts on the first try with starting fluid. If it does, that tells me the pressure isn't there that is needed. It is a much cheaper way to check my theory.

Let me know.
