Hi
Some details: I have a brand new "mercruiser/gm 3.0" engine with all the bought components brand new too.
So far so good but the engine wont start - i have tried many days now and i get no progress at all.
I have regulary spark at all 4 sparkplugs and the fuel pump gives good pressure too.
Its a EST Delco ignition system.
The engine is in my boathouse before installing it to my boat and there is just for now simple wirings, e.g. wire from battery direct to coil (the purple wire). And the two with wires from distributor is cutted and the black wire from distributor is not connected anywhere. Nothing to or from alternator or any wiring harnesk. I tried to ground the blackwire and tried it to positive 12 v - at 12 volt connectiion the sparks go off as it shall what I understand is right too (for shift switching)
I tried to use the basic ignition setup with the with wires too but no help of that.
I have also tried to rotate to widely the distributor when cranking the engine - no help.
Sadly I have no ignition timing light and it takes at least one week to get one here where i live. It is now ordered because I must have it anyway
All what i get - sometimes - is "the big bang" from exhaustriser...terrible and scary
No tachometer is installed or anything else - no wiring at all, ecxept the "must have" to start the engine. Only the 12 volt to coil and the wires from coil to distributor (there is some filter on that -noisefilter for radio?)
The battery is good and cranks the engine very rapidly. I get 13 volt at the distributor from the coil - the pluswire.
The firing order 1,3,4,2. starting from the Barr-marine factorymarked number one. I have checked Youtubes and compared that number one is the correct one.
I tried to make some ohm-metering at the coil.....all was good except that i had 1,2 ohm where the est delco manual says 0,4. But i am not good at these electrical things and maybe my cheap "all-purpose" handyman-meter cant take such low ohms (I think so). My lowest metering for ohm starts from X 200.
The pins at those keyed connectors are all okey - I found out by Google that those pins can sometimes go out of order. I checked and i must say - really bad construction so i put today some rapid glue to secure them better in the base.
Please try to help a man in big trouble
