Hi all,
Hope I could get some help, I had a Mangnuson tvs 1900 supercharger put on my truck and after a few months the lifters clasped so I had the replaced and since I was getting them replaced they suggested me to replace the camshaft and by doing that I also had to reinforce the transmission so we also had that done. That required me to take it to get toned I got it back from the toner and I got it back with it having problems in the cold start, after I got it ruining took it for a drive and when I stepped on the gas it shut off and have not been able to turn it on since. I replaced the fuel pump and also the high pressure fuel pump and it still doesn't turn on. Any ideas???
