I just got done with all the wiring and hooking everything back up. except the vacuum line on the vapfr. tried to start the motor and nothing. we get alittle hiccup but nothing that big. we have spark. the timing set right at the #1. and close enough to get started and tune. but the car won't fire. any suggestion. sort of need some answers fast need the car back on the road. here are some of the motor specs.

are the injectors firing?

 

You don't mention fuel. Are the injecotrs spraying? If not, then you need to make sure you have fuel pressure.

 

Agreed. Also check to see if your pump is running and your fuel relay is not shot. You may have the distibutor 180 off.

 

yes there is fuel alot of fuel that would be the 80lb injectors. we took the distributor off and checked the it and we were off by one at first fixed it and also do the finger trick. everything was lined up and nothing just a very little hiccup.

 

It could very well be flooding out, especially if its cold out. With a near stock tune a modded engine can be difficult to start when winter has set in. Try blocking the throttle open to dry it out. You could always disconnect teh injectors and crank the engine over to clear it out but with a new motor its probably best to avoid unnecesary cranking. Next time, try manually advancing the dist. while the engine is cranking to help it start up. Dont turn it alot, just a little ahead and back to help it start and run.

 

thanks for the input any more ideas shoot them my way. we are going to get it running tommorrow or thats what my engine builder said. thanks alot.

 

You either have a fuel or ignition problem unless you left a rag stuck inside your intake. It only requires three things to make an engine run, air, fuel and a spark at the correct time. But of coarse you already knew that.

As you said in your second post you have everything needed to make an engine run. So let us know what it turns out to be.

got it running. it runs ok. running open headers and no o2 sensor. very loud. getting the fixed tommorrow. the timing was off by about a 1/8 turn. and since it wasn't firing it was flooding the engine. thanks for all your help everyone.
