Hi! I'm having problem getting my ls/vtec engine to start up. The engine is in the car and everything is hooked up except for the header. When I turn the key the engine cranks over and there are flames (flames shoot out all the way to the AC fan) shooting out of the engine. The flames shoot out from the number 3 and number 4 exhaust port of the cylinder head. It would also shoot out from the #1 and #2 ports also, but not as often. I can see the flames and hear the air getting sucked back into the engine. Flames also shoot out of the throttle body when I give the engine gas and the butterfly opens. The spark plugs are wet when I remove them. Does anyone have any ideas to help me out? BTW, I have a B18A1 block GSR head.

 

sounds like your engine is flooding. verify your fuel connections and check fuel pressure. you may want to put the header on, number its gonna be louder than hell and number 2 i don't believe its good to run sans header.

 

I put the header back on and re-did the timing again and it still doesn't work. I checked the order of the plugs and the order of the fuel injector wiring and everything seems to be right. However, when I go to start the engine up, I am getting the suction sounds and a flame shot out of the header outlet. There's a flame shooting out of the throttle body when I open up the butterfly. Any other suggestion would be appreciated.

 

I sounds to my like there is WAY too much fuel dumping in the cylinders. The way you are saying it is pollping flames out but will not start leads me to believe that you are flooding the motor.

 

How do I control the amount of fuel to the engine? I am using an AEM fuel rail with stock injectors and stock fuel pressure regulator. Do you think there is too much fuel still left over in the cylinder and I need to dry that out?

 

Just to let you guys know. I am using a 94 integra wiring harness and did not hook any wires to the vtec selenoid yet. Will this make a differenence? Just to be sure, I hooked the spark plug wires up in this order.

Distributor:
3
1 4
2
In clockwise order with 1 being the position with a little "c" stamped on the distibutor.

Engine:
4 3 2 1 One being the end closes to the timing belt.

 

If the header isnt on, how is the ECU going to get a reading from oxygen sensor. But ya try all that stuff they said and hit us back. Patients is what you need,, dont kill the import dream before you get it all together trying to start the joint half *** together.

 

get an fpr, and then run a compression test... check spark plug gap make sure your throttle cable isnt too tight.

Sounds like the engine is loading up with fuel. Make sure the engine is in time. Not just with a light, but make sure the crank pully and cam gears are correctly in time. Next, check your firing order again. 1-3-4-2 is the order, #1 on the distributor is marked by a C, and #1 cylinder is at the timing belt. Also make sure your distributor isn't 180 degrees out.

 

i would first check valve timing, not the fuel.
