I Have just installed a rebuilt engine. When trying to start It for the first time it cranked normally.As I was sitting in the drivers seat I noticed it was running fine for a first start-up,But then I noticed gas shotting from out of one of the injectors.I turn the car off and inspected the injector and tried to start the car again and now it's having a hard time cranking,but it does crank it just takes awhile. My question is what do i need to do to make the car crank right up?Or would It be fine once I just change that injector?

You may have damaged an injector (O-ring) seal during installation. You'll need to remove the injector (I'd recommend resealing all at the same time) and inspect upper and lower seals. Does the oil smell like gas?
Once you get the injectors resealed (or replaced), change the oil and filter if contaminated with fuel.

Hey loren, I just replaced that one o-ring,that stoped the gas leak, but I'm still having problems. The car is acting as if it has no gas. It starts with starting fluid but dies in about 15 secs. . I've also noticed the car shudders really bad when holding down the gas pedle.My Question is what do I need to do now?This is a first start on a rebuilt engine. I think i can hear the fuel pump come on and off I can also see gas in the fuel rail. Do you think i am not holding the gas pedle down long enough or what. please help this car has been sitting for about 2 years.

Iceman; Sorry, but I can't remember what engine this has? When you open the throttle on a fuel injected vehicle during crank, it really doesn't do much, other than allow more air into the intake. If the engine is flooded, holding the pedal to the floor actually shuts off the flow of fuel to the injectors. Pumping the throttle does absolutely nothing, other than making your foot tired.

If you are getting fuel to the injectors and spark to the plugs, then, obviously something else is going on. Have you double and triple checked cam timing and distributor installation? Pull a couple of plugs to see if they are wet with fuel. You may want to do a dry/wet compression test. If it runs for a few seconds on starting fluid, then I would have to assume that there isn't a spark issue. It running (on starting fluid) poorly, though, could indicate any number of problems, such as too much fuel (starting fluid has a much lower flash point than gasoline), cam timing, poor fuel pressure, ect. You may want to pull the PCV valve out (leave the vacuum line connected) so you aren't pulling rich vapors from the crankcase. Let us know as much info as possible. What engine, what you have done to the engine prior to installing (timing belt, ect) as you can.
