Car Won't Start after headgasket change. HELP!!

[alpalwal]

I have fuel going in to the cylinders and i checked injector pulse on cyl #2 and there was one. I have good compressionMy timing is at about 15* btdc using static timingThe car cranks quickly because it is hooked up to a battery packI have spark all the way at the plug at least on cyl 1 and 3

so let see. fuel, timing, compression, spark = a not running engine

it doesn't even catch at all. just cranks.

This is all after just replacing a headgasket because i blew my other one.

This is a 93 240sx ka24de. HELP!

tried it without the maf hooked up

fuses are all good

ecu had a crank position sensor cel.. put in a new distributor and no problems were solved.

any other ideas? I'm **** out of ideas!

cam timing, possibly, check to make sure its on #1 TDC on the dizzy when the engine is on #1 TDC compression, sounds stupid but its sometimes overlooked.

[alpalwal]

i think the bottom chain might be off a link. would i still have compression? If it was off a link could i just compensate by moving both cams one link left or right? I really really don't want to pull the front cover.

Did you have the crank pulley set at (b)tdc?

Was the #1 piston almost at the top of its stroke?

Were the cam lobes for cylinder #1 opposing when you set the timing?

Was your rotor set at the #1 position after installing your distributor?

Are all your injectors connected?

Did you replace the fuse for the fuel pump?(Assuming you pulled it and cranked her a couple times to relieve the fuel line pressure)

Did you re-connect all the ground wires?

yes to everything, i put an injector on a test light and it was firing. also, the plugs get wet after a while so i know there is fuel.

i didn't disconnect any grounds.... i left the intake mani in the car when i pulled the head.

I know it is at tdc for number one because i put a screwdriver down the plug hole and i then turn the motor to the second to the left timing mark on the crank when the screwdriver is up.

I have also pulled the cover to check the upper chain and that is right and the cams were pointing opposite.

could the lower chain have moved a tooth by just sitting there with the front cover on? i didn't think it could which is why i didn't tie it to something

First make sure you're getting spark at all the cylinders, not just #1 and #3.Most likely the ignition and/or the cam timing is off.

On the DOHC motor, the chain will not separate from the crank sprocket when loose so you don't have to worry about skipping a tooth.

Here's a procedure for checking timing:

To recheck your cam/ignition timing, first disconnect the ignition coil wire, remove all the spark plugs and remove the valve cover. Have someone tap the starter while you have your thumb over the #1 spark plug hole. Once you feel compression, insure that the block timing pointer at the front pulley is pointing to the zero mark on the pulley; if not, manually turn the motor clockwise or counter-clockwise by hand until it's pointing to ZERO. Remove distributor cap and insure that the rotor is pointing to #1 firing position. The #1 piston is now sitting at TDC COMPRESSION STROKE. The two chain mating marks should at their cam gear marks; intake at 11:00 o'clock and exhaust at 2:00 o'clock.

Here's a picture:

ive already did that and i even counted links in between everything to make sure they both weren't off the bottom sprocket.

so youre saying that if i had the front cover on but the bottom chain loose the chain could not have skipped teeth?

[alpalwal]

ive been trying to get it to start again and now it fires 1/2 the time ish, but it still doesn't start. It definitley seems like timing, but the distributor and the cams are on right. if the lower chain can't move with the front cover still on then what could it be?

[matt4pl]

you try moving the dizz around at all?

[alpalwal]

ya... but it was best when it was in the range of the screws that hold it in.

[matt4pl]

i meant with the screws in, move it to one end, tighten, try it, move it to the other end, try again, etc. are you letting the fuel dry out too? if its flooded it aint gonna start

[gthammers]

Check which direction (CW/CCW) you count your plug wires on the distributor. I think from #1 (front) you go CCW to continue to #2,3,4.[I did this wrong the first time.]

You checked your firing order?
