I hate to waste everybody's time with another hard start question but need a little help. I have a 06 CC
with 260000 miles. Had external oil leak due to bad oil cooler gasket. I took it to a garage and had them replace the oil cooler and egr
cooler while they were in that deep.
Got it back and had a long crank times when hot due to low icp
oil pressure. Took ipr
out and it had a crack new style cap and bad o-ring. Replaced them and did an air pressure test on the hpo system with an ipr
adapter to shop air. Found number 5 and 1 injector top o-rings leaking. Replaced injector o-rings with Alliant kit and oil rail cup o-rings with Hbh kit. Checked with air again and all seemed well. Put it all back together and drove it for a couple of days with no problems.
Now I'm back to having a harder time starting it hot. Here's my readings while cranking:
While running idle:
I do have a P0261 code injector 1 circuit low that's new. I changed the oil and fuel filters. Have checked all wiring harnesses. It starts fine in the morning and when it finally starts hot it runs normal. I checked the fuel filter bowl is full do not have a fuel pressure reading.
I bought it used about 6 years ago and did a blue spring upgrade and a number 8 injector back then and the work above this year.
Any suggestions would be greatly appreciated!
