What's up peoples, it's been a sec since I have been on the forum. I need some guidence. I successfully swapped an h22a into my accord a couple years back. The only engine code I was throwing was EGR related. Fastfowarding to this past year. As it got cold my car did not want to start. I would take the plugs out and they would be wet from gas. I wasn't sure if some sensor on the car was telling the car to dump fuel when it didn't need to. Since then to try and correct the problem using advice and gut feelings, I replaced or rebuilt the entire distributor, coolant temp sensor, fast idle valve, spark plug wires, fuel pump, fuel filter spark plugs, oil pressure sensor, ECU and I am still having this starting issue (only when the temp begins to drop). The only known issues I know are the egr valve according to the ecu may be having some issues (low/high lift something) and I have a small crack in my exahust manifold. Both of these issues I think are separate from my starting problem. Has anyone experienced cold start issues that they were able to resolve? If so I am in dire need of help since winter will be fast approaching in months to come. Thanks Paul

Flooding is usually the result of fuel delivery problem, either leaking fuel injectors or perhaps a bad fuel regulator. Couple of things to check.

First check the vacuum line to the fuel pressure regulator to see if it smells strongly of gas. If yes, you probably have a ruptured fuel pressure regulator diaphragm. This allows gas to be pulled into the engine through the vacuum line. New fuel pressure regulator should fix the starting problem.

Second is more difficult. You need to check the fuel pressure to see if the fuel pressure is declining rapidly when keyswith is turned to OFF after allowing pressure to build for 5 seconds w/ switch ON. If fuel pressure drops rapidly, one or more fuel injectors are likely leaking into the engine. A fuel pressure check kit is required to check fuel pressure.

good luck
