My 89 240sx with the SOHC KA24E wont start up. I just did a head gasket and timing kit job on my car due to the infamous guide falling to pieces. So I had the head resurfaced, pressure tested, cleaned etc. . . Installed new gaskets on everything! Put it all together and --- it just turns over and wont run.

The timing marks are lined up correctly according to the FSM. So I assume the timing is correct. Every hose and wire is hooked up. I am fairly sure I hooked up the vacuum hoses correctly. I labeled everything but the e.g.r. hoses and the 3 hose connections at the bracket on the rear of the cylinder head. Anyway,

I don't have any antifreeze in it, but I have new oil in it. is this causing it?

and I didn't bother putting all the belts on, but these are 'accessories' - so its not like that would make it not start, right? I just want to make sure it runs before I button everything up, ya heard?

I am jumping my 240 with another car because my battery is crappy. I know you should have a strong battery, but if it turns over, say 100 times but wont start, I doubt its a weak battery making it not start. It also seems to be turning over fairly quick. sometimes it sounds like it wants to fire on a few cylinders but then just turns over. I noticed sometimes the number 1 cylinder spark plug gets wet with gas, although I never took the injectors off or out of the intake manifold. I'm not sure whats causing it to get soaked... bad spark? I have a new cap, and the rotor isn't new but looks ok? I don't have new plug wires... but they worked on the car before I did the head gasket and timing job... so what gives!? =(

I also have it jacked up on jack stands, maybe a foot or so. Would this cause it to not start? I still have to bolt up the sway bar and put a front tire on, so I didn't want to lower the vehicle just to have to raise it back up.

what am I missing!? I am desperate for a vehicle and I need to get this pile of bolts running! Thanks for any help!

check your fuel pump. it could be bad. also you said the battery was no good. i would go ahead and change it to see if it starts working or you can clean out the connections before you change it. as for the gas going in the spark plug, i cant help you there. somebody else here can answer that for you.

I can hear the fuel pump when I turn the key to 'on' & the fuel pump worked fine before the repairs. Im stumped!

Gunmetal - are you getting fuel on any spark plugs? I have noticed my number 1 cylinder spark plug gets flooded. Maybe the other 3 injectors are not working? bad plugs? idk. I got a new battery tonight, so tomorrow I'll drop that in and play with the injector wires. keep it posted
