I have to hold the throttle wide open and hope it fires up. It cranks sloly and is just drawing so much power the lights dim does anyone have any idea what could be causing this. It just started happening within the last week.
A bad battery is not going to blow the main fuse nor will a main relay, you have a short to ground in the starting system. Check the + cable from battery all the way to the starter solenoid B+ terminal. If the cable looks good you have a short in the starter solenoid/motor windings. When ambient temps increase the resistance in the starter windings increase as a result it draws more current.

You have a short it you are blowing a 150 amp fuse. The short may only show up once you get warm though. I hope you have very large cables from the battery, especially since they are no longer protected by a fuse . Find the short and fix it, this is a fire waiting to happen.

Weel I drove home tonight and then went out to go for a drive and I had to hold the pedal down for it to start. Doesn't this mean that its getting to much gas and you need to hold the throttle open to get some oxygen in there to combust?? What could be causing this am I running to rich and flooding it out?

Mine does this too, I thought it was an AEM FMU issue. Many others using it have had the same issue too
