Mackpro Posted May 1, 2012 Share Posted May 1, 2012 I would start with a fuel supply pump, unless it has been changed lately. I know we put alot on. We had a 06 CV in here yesterday that would barely run and that fixed it. Once it is running, does it have as much power as it did before?

mtr Posted May 1, 2012 Author Share Posted May 1, 2012 driver says it seems to run fine but idle has me concerned. would supply pump affect idle also can supply pump allow fuel to back down (checkvalve) Quote Link to comment https://www.bigmacktrucks.com/topic/24863-no-start-06-cv713/#findComment-117146 Share on other sites More sharing options...
Mackpro Posted May 1, 2012 Share Posted May 1, 2012 driver says it seems to run fine but idle has me concerned. would supply pump affect idle also can supply pump allow fuel to back down (checkvalve)The check valve could be bad, its on the pass side of the block above the air compressor. The idle issues is probably that the driver hit the cruise buttons just right and lowered the idle speed, it happens alot, I always turn this feature off in the parameters to keep this from happening.

demolitionman25 Posted May 2, 2012 Share Posted May 2, 2012 Hey mackpro do you think it would be wise for him to also check fuel lines and make sure they are tight cause i have a 95 ch613 when i bought it it was having trouble starting like MTR is having the fuel system bled off after a couple hours and in the mornings it was a pain till i had enough and every connection i check and all cooper washers and i found a washer had a slight blemish changed it that cuired the problem cause i was talking to a company about fuel pump and associated items and i was looking at almost $6000 and come to find out a $1.50 washer was the problem Quote Link to comment https://www.bigmacktrucks.com/topic/24863-no-start-06-cv713/#findComment-117271 Share on other sites More sharing options...
