help 240sx convertible after compression test it wouldnt turn on
it runs and drive np before.

After my friend did compression test on the motor to see the PSI on all four cylinder x2
now it wont turn on.

so far i replaced brand new fuel pump.
dizzy cap, new wires, new plugs, new fuel filter, battery was semi dead after compression test.

i'm thinking timing might just skipped

original ka24de with 5 speed swap.

Have you verified if you have spark/fuel? You can check fuel by pulling the rail loose and seeing if all four are shooting at the same time while cranking. Otherwise a noid light would be easier.

bmxer882x · 09-17-2015, 01:11 PM

umm, did you double check you hooked your plug wires back up right? if nothing was changed you shouldnt have any issues.

iLagX · 09-17-2015, 01:56 PM

fuel and spark is there.
yeah i also forgot to stated my friend the idiot
put the coil wire in cylinder 1 of and the other wires went all over the places.
as of right now its in the correct order.

what do you guys think he short or damaged?

I'm not going to say that it is impossible, but it is pretty damn difficult for a chain to jump a steel tooth on a sprocket.

Can you please put this in proper English/grammar because this shit doesn't make a damn bit of sense.

Is the engine cranking/turning when attempting to start the car?

Check fuses

iLagX · 09-19-2015, 12:57 PM

i've check the fuse everything checked out perfectly. nothing blown.
starter cranks but it doesn't turn over. Almost like timing is off.

Ignition coil wire was placed on the first cylinder dizzy cap
which it was suppose to be on the center.

stop blaming you friend and take responsibility for your own actions, you replaced the "dizzy"! look up the proper spark plug wire locations. Every idiot says timing must have jumped, yeah i guess it did, sense it happens so often now, but never in the first 20years of that engines life. The engine should basically spin over really easy during a compression test anyway. I want you guys real names so when the zombie apocalypse happens, we keep you in the garden, where your skills can be utilized best.

S-Verteen · 09-21-2015, 08:33 AM

If your starter is "cranking" so is your engine which means it turning over. Id suggest a google search for your firing order, then maybe it'll start.

kruked · 09-21-2015, 10:33 AM

Car ran fine before compression test... so, we're assuming that the only thing disconnected was the distributor. "Someone" put the coil wire on the #1 position of the distributor... is it possible that the distributor shortened out from an over-load? I don't know if it's possible or not, (maybe someone can chime in on that scenario).
Check your plugs? Expecially the #1 plug? I mean, we all know that a car will run like shit on 3 cylinders, but...

If you're not aware, the distributor cap has the firing order on it. The engine is 1 2 3 4. 1 being closest to the radiator, 4 being at the fire wall.

Something else isn't adding up. Are you sure that you're giving us all of the details as of to what your "friend" did? I don't see how a simple compression test has gone hay-wire.

zombiewolf513 · 09-21-2015, 03:46 PM

Battery dead? Leave injectors plugged in? Did you plug everything back in?

iLagX · 09-22-2015, 12:04 AM

battery was dead after compression test.
injectors connector is plugged.
Battery got replaced same issue.

Yes, i was wondering if it is possible the distributor got shortened out?
or what else would cause the issue?

S-Verteen · 09-22-2015, 08:44 AM

Are your spark plugs fouled out (completely black, ashy, or stinking like gas)--replace? If you have fuel and spark id guess its the plugs. If your distributer or ecu was shorted out there probably wouldn't be fuel or spark.

zombiewolf513 · 09-23-2015, 03:23 PM

Did you leave your fuel circuit plugged in while you did you compression test?

KAT-PWR · 09-23-2015, 04:36 PM

Okay based on the angle of the sun where i am i think i deciphered what your posts are trying to say.
Your friend connected the coil wire to the #1 plug output and you fools tried to start the car sending that voltage into an output. I would imagine that would cause some damage?
Try another distributor
