ok so its a 96ka24de in a 93i put the 93 intake mani on it and im running aftermarket hedders.o and a 93dizzy too.

nowthe motor is in. its finished, all things plugged up, wired up, grounded, fuel lines good, all fluids good, new plugs and 8.mm wires, coil is good, dunno why it wont start.

i checked for spart, im getting spark from coil to dizzy to wires to plugs good

im getting fuel pressure atleast to the fuel filter(filter is new to)

fuel injectors seem good, i checked ohms reads 11.8 on all.and when plugged in they click click i chekd wit stethascope.the plugs are also reading 12volts so the harness has power.

i smell fuel on the end of plugs when ipull them out, not alot but i do smell fuel.

i do have a qtr tank of gas

02is good

other sensors are good.

all the relays and fuses are good.

i dunno why but it just wont start up.

it turns over and over and over and over and sometimes acts like it wants to fire up, like it studders but dont fire up.and i sprayed carb cleaner stuff in the intake while was starting it and IF i do that it really tries to start up. started once for about 1.5sec lol but dropped off.SO because of that test i ASSUME that im still not gettin fuel..... i thinki know the spark is there so if the choke cleaner tried to ignite that we put in the intake then why wouldnt FUEL?

plzz helpme out

ummm....its not the intake that you spray the carb-choke cleaner in. you spray it in the manifold opening. make the mouth open and spray in there. I had the same problem too. but what i think your problem is, it needs more spark. a powerful spark. get a cloth or a suction tube. make sure your octane is "91" . 1.Remove your spark plugs.2. Dab the cloth in the gasoline or use the suction tube 3. and squeeze about 4 "drops" of gasoline into the chambers (all 4 of them)4. Put the spark plugs back on and FIRE IT UP!. Make sure you have a strong ground to the engine block and strong battery connection.

good luck!
