mackrmodel686st Posted August 30 Share Posted August 30 I drive a 2001 cx613 with the E7-427 vmac iii. The truck starts right up in the mornings when cold, but when re starting after it's been warmed up will either have a long crank before restating or no restart at all without starting fluid. The transfer pump has been swapped out a couple times and a check valve was added to the fuel suction line from the tank at the filter housing. No change in the issue. Has anyone had this problem and been able to fix it? Thanks in advance.

Joey Mack Posted August 30 Share Posted August 30 over heated relay? check fuse 40 in the fuse box under the hood next to the steering shaft. clip a home made ground wire from the EECU housing to a good ground on the block.. put the ether away,, It will get addicted to it, and then....... I assume that with the new pump you have tried to prime it up firm, and still no start? is the oil level rising? is the oil getting thin? fuel diluttion... do a halo test on some clean cardboard, the brown stuff.. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74513-2001-cx613-vision-crank-no-start-when-warm/#findComment-557830 Share on other sites More sharing options...

Truck just got a new motor, the old block cracked. Was having the same issue with the old motor. Oil is fine. I'll try the a ground. I'm assuming fuse 40 is for the ecu, correct?

JoeH Posted August 31 Share Posted August 31 Any codes? Long cranks before start sometimes means your either your cam or crank position sensor isn't reading. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74513-2001-cx613-vision-crank-no-start-when-warm/#findComment-557846 Share on other sites More sharing options...
Joey Mack Posted August 31 Share Posted August 31 I guess you re-used the cam and crank sensors? the crank sensor (RPM-TDC) harness can be damaged easily, causing a bad connection.. JoeH is right. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74513-2001-cx613-vision-crank-no-start-when-warm/#findComment-557848 Share on other sites More sharing options...
