Welp, she started on the 3rd round of cranking. Watched IPR hit 85% and ICP slowly rise over 500 and start. Let her idle for awhile and took her for a spin down the road. Got on it pretty good and POW...hot side popped off. No big deal, just a few miles down the road, turned around and limped her home. No damage, band clamp was hanging out in the engine bay..no big deal. So I decided to go ahead and try to restart. IPR 85% but ICP won’t rise over 300...same issue again. I’ve done some searching, some reading, and I am thinking STC (new) or ICP.
I’ll list mods on my truck before we go any further.
07 with 166,000
K&N intake (next thing to go, POS), EGR delete, P-max turbo, studded, heads machined, chromoly push rods, BPD full oil cooler kit, all new gaskets and seals from heads up. STC was updated for the BPD kit. The shop said my standpipes and dummy plugs were already updated and they just added new seals. I’ve had long crank issues since I got it back, but not when hot, been talking to BPD and the shop the entire time. Since I got a no hot start a few weeks ago, we thought dummy plugs and I decided to do this myself rather waste a 3.5 drive to TX and the difficulties of hauling two kids + wife to following me down and have to retrieve the truck at a later date. Anyways, FICM 48.5-49. Batts looked like they were starting to fail when I got the truck back so I went ahead and put brand new interstate batteries in.
I haven’t noticed and rough idles, no surging, or anything otherwise to make me think the truck was running bad. Everything appears to be fine once started. IF I disconnect the ICP and the truck starts fine, would that indicate ICP has gone bad? Or to symptoms otherwise dictate that nothing is wrong with ICP and I should be looking further back at STC. I’m hesitant at pointing fingers at the shop, because I honestly think they do good work. I’m not going to blast them either, everyone makes mistakes.
Also, BPD customer service is top notch. Andrew is a good dude, after eliminating the BPD kit, he still was ready and willing to continue troubleshooting with me.
Thanks for the help. I plan on putting that bolt in whenever I decide to go with bigger injectors or get bored and want to pull the valve cover.
