My 98 1.6L 170,000 miles LX (d16Y7) civic seems to take twiceas long to start in the morning. I change the batterylast month(14.5 volt while car running, Change sparkplugs, new air filter, new fuel filter, new pcv valvelast week. Replaced wires, cap, rotor last year they look ok and measure within spec. I even use fuel injector cleaner does not seem to help the problem. I also notice that a trace of coolant under the distributor so I change out the heater hose and problem did not go away.That a sensor with one wire on it. What is this sensor anyway? Could that be the problem. I see somemoisture on the wiring boot too. The car drives normal in the afternoon when I leave work. It starts up right away! The engine sounds normal and runs at 34MPG . What can be wrong? Any info will be great. Thanks in advance!

I'm a a retired auto mac., and I have seen this happen a few times. You're problem sounds like a fuel pump pressure check valve. You're car has a pressurized fuel system to enable it to spray fuel out the injectors. The fuel pump provides the fuel under a certain amount of pressure. The pressure doesn't drop off to a critical point during the day time, but you let the car set long enough, such as 8 to 12 hours at night, and the defective pressure valve allows the pressure to drop of too low to start. To compound the problem, you are using the battery juice on the starter trying to start the car, and the pump can't get enough to build the pressure up. Try turning the key on and off several times before hitting the starter. This will allow the pump to build pressure before you try to start. The only fix is either using the key on and off method or replace the pump. Good luck.

particular, it might desire to be the temp sensor for the ECM. yet that's additionally the time of 365 days whilst vulnerable ignition structures start off enjoying havoc with chilly starts. aspects that motorist look to have forgotten positioned on out- spark plug wires, caps and rotors. additionally if a greater value-effective kind of gas has been used, moisture from condensation can come into play. returned as quickly as I have been given my first street worth automobile, I found out correct to the each year track up. Spark plugs basically lasted a 365 days so we've been given interior the habit of servicing the ignition gadget a minimum of each year. Now lots of those area final longer then the 1st proprietor has a automobile and this falls on the 2nd proprietor to repair them. So replace the consumables interior the ignition gadget and positioned some gas antifreeze interior the tank. between those 2 the opportunities are the project will bypass away.
