Ok guys, I’ll try and be as accurate and succinct as possible.
two years ago, the boat had a new long block installed. Then she sank. Bellows tore i believe. Repairs were made and she was ran for half a season. The last trip she shut down. I noticed that there was a ground left unconnected and the ground bus had melted. So, this season I’m trying to get everything running again.
what I have done so far to my 1997 5.7LX Thunderbolt V
1) replaced the ground bus bar
2) replaces the coil
3) replaced the plugs, cap, rotor, and wires
4) filled tank with gas
5) replaces fuel filter
6) changed Oil/filter
7) replaced both batteries and double checked the block is grounded to one battery and the bus bar. Both batteries are connected at together at the negative terminals.
now, fuel is getting to the carb. I can see it squirt in when I pull the throttle cable.
I don’t seem to be getting a spark. I pulled the coil wire running to the dizzy and I didn’t see a spark jump While cranking. I did the same thing to a plug wire and saw no arch.
The coil appears to have a resistance of 2.2ohms between the positive and negative, but I did not remove any connected wires. Google says that’s a little high, but idk what specs are without a manual. When checking voltage At the coil + KOEO, 9.9v. It is suppose to have 12. Not sure what is going on here. Due to increased resistance inside the coil?
I checked the voltage, KOEO, of the red and white wire coming out of the dizzy and it was 0. Ignition module?
the diag tree I found here says to check the tachometer wire at the gauge, but I have not opened the panel on the head yet to check.
so, what are yalls thoughts? Anything I need to add to aid diag?
thanks!
