Message: [QUOTE="Copracr, post: 480347, member: 4257"] Sorry, but yes it would crank a half second, everything would go dead for 1-2 seconds and I moved the key to the run position, then eveything wakes up and the starter would begin cranking until I turned the key to off. But here's the update: I figured I had bad injector o rings and/or cups. It was either that or I smoked the engine, so I set out to fix the issues I could. I bought a compression tester, an adapter so I could use my coolant pressure tester, and my big purchase was the whitaker cup tool and o-ring kit. 1st cylinder on passenger side had no compression. I had bought a 5 dollar adapter that was made to do compression tests on pre-powerstrokes and I had to R+R the 1st rocker arm to R+R the tester itself. Turns out I didn't have the pushrod seated right or something because it was bowed real bad. I stuck the pushrod in a crack in the floor and whacked it with a hammer as straight as I could get it (which was still noticeably bowed) and the compression comes up into the 200's now - woohoo. I have 2 pushrods on order and should be here any day now. 3rd cylinder back on the passenger side was low compression (low 200's), so I swapped out the cup and o-rings - meticulously. Compression is high 300's now. 4th and 2nd cylinders were high 300's, but I may re-do the cups before I button it up just to be safe. My next move is install the new pushrod and see what the compression does. If it comes up I'll R+R the rest of the cups on that side. Then pull the other valve cover and repeat. I was wondering though - If I get compression roughly equal in the high 300's across all 8 cylinders then blowby is necessarily good - right? [/QUOTE]
