240 cranks but wont start has spark and fuel

Post by **mackdaddy240** » Mon Oct 11, 2004 10:08 am

Ok I have a 92 240 that ran great, i blew a head gasket put a new one in and put it back together now it wont start. It has strong spark from a msd ignition, new plugs, and its getting fuel I took the hose off the top of the filter and it spray fuel about 2 foot into the air when i put the key ON. I put new plugs in and tried to start it, still nothing, I took the new plug out and it smelt like gas. I reset the timing again and it still wont start. I'm out of Ideas it has gas spark and its in time WTF!!!

if anyone has any ideas it really like to get my car back on the road, the last local import races are coming up and I'm planning on running. plus its my DAILY DRIVER IM STRANDED HELP ME!

Turn your distributor 180 degrees (flip it around).

Post back with results.

edit: you're going to have to pull it out and put it back in to do this.

That is a great Idea!!

Did I detect sarcasm in that post?

Do you know for sure its in time? If you replaced your distributor you may have put it in backwards (such was the case for my friend mark). So his car was in time, but the distributor was 180 degrees off, so the damn thing wouldn't start. Just giving you my experience, gosh.

Well, if you messed around with the chains, you have to set the timming with both the bottom chain and the cam sprocket chains. I'm sure it don't start because of that. As for the 180 degree thing with the distributor.... that would work for a honda but not nissans, It's got way to many teeth to know which is exactly 180 degrees and even if you do so, you're probaby not at 0 degres to start.

He would still be off time, but it would start, and at least he'd have somewhere to work from. I know what you're trying to say though.

Yeah, nissans are a pain in the frigg'n @ss when it comes to timming.

My bad, I thought you were being sarcastic with me the first time. No that wouldnt work because there are 2 bolts that hold the distributor on, if I was to somehow fit it back in 180 backwards the two bolt holes wouldnt have anything to bolt into. But thanks for the idea I thought you were just ****in with me.

BUT I think I might have figured it out, I know that if your water temp. sensor goes bad it will make it run rich, I'm hoping that the snesor is bad and its making it flood. Because right before I swapped the ka24de the ka24e was doing the same thing and I remeber I put the old water temp sensor from the 24E in my DE. but it ran fine for about 2 months until I changed the head gasket so I'm going to get a new water temp sensor and see what happens, I'll post the results.

Hmm...somehow we put his one backwards and it still bolted up correctly...

I wish I could help you out more but now I'm stumped.

I'd take a compression reading on all cylinders first, then start looking at the timing issues and possible flooding problems. You can set your dist 180 off, it is possible (although not a precise 180 due to the teeth if we're splitting hairs here).

Just set your crank to tdc before you pull the dist. and it'll be easier to line up.

It's all compression, fuel, timing and airflow

Well it wasnt coolant temp sensor...... I didnt think that would fix it but I figured it was worth a shot. I guess I'm going to have to tear back into it and check the chains again.

I had a VERY similar problem when I swapped a DE into my E chassis. Anyway, I was getting spark and fuel, like you, redid my timing, like you, then I tried advancing and retarding it. What it ended up being was that my distributor was 180'd out. When my motor was trying to crank, it wouldn't start the firing sequence because it was firing plug 4 first, not plug 1. Now, the SIMPILEST way to fix this is to take the wire off of the distributor cap at the 1'st and 4'th posts and switch them. Give it a shot.

If youpost a pic of your physical timing(timing gears and camshafts) with the engine on TDC it would be alot easyer to figure out the problem as well

Check to make sure your injector O-rings aren't leaking. I take it you did remove the injectors to remove the manifold and head. Disconnect the harness to each injector, pull the fuel pump fuse, remove the spark plugs and crank the motor with the throttle open. If it's flooded, you should see some fuel make it's way out of the spark plug holes. Once fuel stops spitting out, install the fuel pump fuse. Try cranking again. If fuel starts spitting out of the spark plug holes again, you have a leaky injector O-ring. Replace them with new ones(which should have been done the first time around).

I tried that one. I tried about everything I could to the outside of the engine. I finally advanced the timing way beyond stock by taking out the distributor and turning the rotor. I unplugged the spark plugs and cranked it full throttle and it fired up, backfiring like a mother ****er then died. SO i pull started it with the timing really advanced and drove it to my uncles shop missing the whole way. I took off the valve cover and the top timing chain cover and saw that the links had jumped. My only guess is the tensioner has gone back and let to much slack in which cause it to jump timing. Now I have to find a tensioner ASAP, hopefully autozone will have it but I really doubt it. anybody know a place online that would deliver overnight?

Corection unplugged the fuel injectors

Well I got a tensioner took off the whole front cover to line up the bottom chain which was a *****. You know you have to take the oil pan off to get the front cover, which means you have to lift the engine out of the bay! But anyway I lined all the chains up put the new tensioner on and turned it over twice to see if it would jump. IT JUMPED 2 links! So I guess when my head got hot and overheated it must have stretched the chains somehow??? So now I have to get new timing chains

just to add my two cents. The distributor cannot be set 180 degrees by just rotating the distributor. I had the same problem. I had had my number #1 spark plug cable in the buttom right, instead of top left.

Well after hours of work I finally got it back together with new chains, sprockets, tensioners, and guides. $294.76! but it was worth.
