It won't fire with the interupt switch wires shorted together
That is how the shift interupt system works. Shift interupt switch kills ignition to make the motor stumble as you shift. Shorting out the switch just kills the ignition
Sounds like you may have a bad shift switch adjustment and...
If you haven't checked the ignition trigger
That may be the only part of the Thunderbolt system that may be an issue. They redesigned from a 2-wire sensor to a 3-wire However it's a work or doesn't thing
I agree with Bondo, look at the fuel system first
Assume it's 250 hours of work. Just the cutting and grinding is 25 hours
At 125-150 per hour shop rate. What corners are being cut?
If you want to do coosa yourself add $1000 to my estimate. It's $200/sheet compared to $40
Your transom and stringer rotted before the floor
To do it with plywood and fiberglass yourself will be about $1500-2000
$200 in wood
$200 in PPE
$100 in cloth
$300-500 in resin
$400 in foam
$300 in misc fiberglass supplies
$200 in sanding discs blades, etc
While the Volvo engine uses GM pulleys. You won't find them in an automotive equivalent
Either visit your GM industrial dealer or order thru Volvo
Me personally, would soak the pullies in oxalic acid for a week (to remove all the rust). Wire brush them and paint them.
Your out maybe $20
your battery lugs were not cleaned with 150 grit sand paper
your battery clamps are wrong for a marine application
as stated above, incorrect or dirty connections will spark.
repairing the cracks is just like repairing anything fiberglass.
agreed, it looks like the core material is damaged.
proper repair would be to remove the top, cut it apart, replace the core, reglass the top, re-gel or paint and then reinstall.
