    Sorry. I was pretty tired last night by the time I got the ecm put everything back together and switched ecms. I had an article that explained troubleshooting SRS/ trs. I felt in the hole with a socket extention, but the article says you are supposed to measure gap somehow and that was over my head. Everything else checked out though. Ohms, open etc. We were putting the new cam in to rule out that being the problem. There is no SELs when I crank. There was a CEL but couldn't get it to flash at me. Still no change. Crank but no start..
     
    Rideandrepair Thanks this.

    Hey. R&R. I see you have changed an injector, did you diagnose this via smoke or something else? I would sure like to determine where I am losing signal for my injectors. I'm sure you have seen. I got fuel like donkey konk. Checked SRS/TRS, but don't know how to measure gap. Switched ecms just to rule that out. But haven't heard any further.

    Can you please humor us and pressurize your tank it won't take much (so you can rule that out) instead of jumping all over the place. Take the advice that is giving to you.

    Dude. I have pressurised tank and got fuel though the system. I even for####'s and giggles disconnected the check valve and pump and sucked it backwards through there. I think there may be some fuel in the head.

    Have you pulled the valve cover to see the injectors and injector harness?

    No. Was looking to ask and get some knowledge prior to. I do have a bit of optimism this morning switched ecms late last night early this morning. Initially last night it had CEL on but wouldn't give any codes. This morning, I turn ignition on I get SEL codes 34, 62,63. I am sure the 34 is just the plugin. Haven't checked and ain't sure how to check CEL codes.
