I have a Nissan S Cargo that won't start, it has spark and has compression so that leaves fuel.
It was running when I drove it into my unit which was a couple of months ago, when I say it was running, it was stuttering when it got hot (say after an hour of driving) but once I left it for 30 minutes it would drive fine again.
On that basis I wanted to fix the issue, I replaced the leads, plugs, coil, distributor cap, rotor arm, distributor module, air filter and welded the back box on the exhaust (can't get a new one anywhere, will have to get a custom one made at some point).
Once I did all that it was still starting.
I then decided to do a little body work, rubbing down scratches etc, I then decided to get it out into the sun to give it a really good clean and here's where the issue started, it just wouldn't start.
It turns over but won't fire, I hear bopping coming from the exhaust, like a little back fire I suppose, I also have a light on the dashboard which is the catalytic converter which is lighting up when I try to start it, could this be the issue?
When checking the spark plugs, they are bone dry although when I took the carburettor off to check it, there is a pool of fuel in the inlet manifold.
Is the inlet manifold blocked and should there be a pool of fuel in there? Is the catalytic stopping the engine running? or is that light only on because it's not been run for a while (well not run for long enough)
I'm not a mechanic but I tinker a lot but I cannot figure this out.
