New engine: starts from second time

Was it working before you had the engine changed?

Have your expert mechanic put a pressure gauge on the fuel lines. I am betting you have a leaky injector or a bad one way valve (check valve) in the system and that the fuel pressure is dropping in the fuel lines when the car is shut off.

Instead of trying to start the car the first thing when you get in, switch the ignition from off to run (but not to start) two or three times before actually switching the key to start. I bet it will start right away then.

Hi Ted, Yes, it was always working well. Alex.

Hi Ed, I tried your trick, it didn't help. I recycled the fuel pump several times hearing it being activated for 2 seconds. Subsecuent starting did not work. Again I had to crank the engine 2-3 times before it went on. Any other idea? Alex.

I wouldn't say that it was harder. I brought it to another shop. They found a loose and dirty connection to the + battery pole. It began start OK, but then the starter became slow and was getting stuck sometimes. It appeared to be that while fixing positive pole they made negative one loose :-). They fixed this as well. Damn, again from the second time. What a frustration. I thought perhaps battery was bad and voltage dropped upon startup so that the vehicle computer was getting mad. I went to Schuck's for a new battery and they told me that my original one is not charged well. I charged it there and the car started from the first attempt. Let's see how well it will be later.

That's such a frustration!!! Again! Only starts from the second time. I also noticed if I push the key really hard while cranking, there are higher chances to start from the first time. Or if it is cranking and the engine is not catching, some wobbling of the key produces engine "coughing", sort of almost starting and then kicking back. I can't believe that this annoying problem comes from the key/ignition switch. Could it be that during cranking I have unstable voltage in the system because of some loose connection in the key department? Thanks for any idea. Already have two mechanics have given up :-).

It wouldn't be inconceivable that the contacts in the ignition switch are bad and that the problem occurring after the engine change is coincidental.

I brough it to the third autoshop. Finally they found the reason: grounding of the computer was loose and during high power demand (cranking) the voltage was dropping below acceptable levels and the computer was getting mad.
