Re: truck wont start
would the fact that whoever did the hei swap connected the 12V source from the fuse block instedd of from the igbnition affect the capacity of it to get enough spark to start?

Re: truck wont start
Is there gas in the tank? Are you getting spark at the plugs?

Re: truck wont start
You should still be getting 12 volts from the fuse block. It's a constant hot correct?

Re: truck wont start
I've seen lots in the past where someone hooked up a wire that has 12v while ignition is on but looses the 12v when key is switched to the start position. Definately double check that.
