Had my R in a parade today and it won't run. It overheated and died. Starts but won't keep running. Any ideas would be greatly appreciated.
Not to bust anybody's chops ( but it is fun to do) this is an important lesson for all the newbies out there and guys who put things off. If you have owned your truck for awhile and been on this site enough you should know by now the major things that should be done to your truck to make it more reliable. Ignition switch , ABS break shield, lower shift connection for automatics, stepper motors, replace OEM fan with Mike's fan, etc etc. Doing a little preventive maintenance before hand and enjoying your ride sure feels better then sitting on the side of the road wondering what the hell went wrong.
The radiator is probably NOT the issue. Your truck is supercharged and has need for a much better fan than the OEM unit. The majority of cooling system problems are related to the poor airflow from an OEM cooling fan...... that goes double for supercharged applications........Thanks for your help. I remember the problem with the fuse box. I guess I should also replace the radiator with a hd one from Mike at Simple Engineering. The R is super charged and also doesn't like to go slow. Also has a different cam. Of course yellow is faster, ha ha
The fan that you will need is the MFK-2. It will move about twice as much air as the OEM fan. You won’t need the manual override. Please check the 3-pin connector on the truck wire harness closely before you order, as I am seeing an increase in the number of burned connections on that plug.Mike, thanks for the offer to help. I need several parts from you and definitely a better fan.
If it ain't broke don't fix it, but have the spare parts in hand.
Yeah, most of us know this stuff, but there is still that (if it ain't broke don't fix it) that also makes a lot of sense. My Chevy Avalanche is also a 2005 model. Now it has around 125,000 miles on it (which is actually low miles for one that age). Am I thinking of swapping out the ignition switch.........Hell no. Do I expect it will be a problem soon...........No I do not.
Meantime, I do indeed with my (2005 SSR), maintain a back up ign. switch and instructions/tools to swap it out if necessary. Am I gonna do it "just for a drill"..........No.
I agree.... Spot on...... The “Magnavolt” box that is used to boost fuel pump voltage at higher boost pressure has been problematic across many of the Magnuson installations.Supercharged and no start .... many people with similar issues report a fuel pressure issue. Check the pressure at rails for 60PSI and also the gray connector at the fuel pump booster mounted on top of fuse box. Problems reported at gray wire connection, charring means sparking and not a good connection. Clean and spread the pins for better connection or replace.
Good news, finally installed new ign sw and it starts and runs fine. Many thanks to Dragun2U, Autoprof and Dicktator for your help and trouble shooting advice. Augie doggie also. Next thing I plan on doing is removing the fuse box for repair.Had my R in a parade today and it won't run. It overheated and died. Starts but won't keep running.
