Try a shot of starting fluid into the throttle body and see if it runs for a couple seconds. It sounds like the fuel pump may be failing. The fuel pumps are a compound pump the volume part is about 10 psi and the pressure part boosts it to 50 or so. The pressure part fails first and poeple think just because there is some pressure the pump must be ok.

Its very believable that its fuel. It was running great and I filled it up at an ARCO in a part of town we hardly go to. That's when the miss or bump I spoke of started. Maybe just coincidence but who knows.
I will try the starter fluid tomorrow. Let you know. Thanks.

Shot starter fluid in the butterfly area twice and nothing at all. Not even a bump. Cranked it three times after each blast and nothing. Battery was charged for a couple hours before.???????
Just tried it again and nothing. I can smell the starter fluid at the rear of the car now.

Back in the beginning of your original problems I asked if your code reader gave any live data. See if it gives you an rpm reading when cranking. The crank sensor is the only rpm sensor, the cam sensor is synthesized by the ignition module based on coil ouput to determine where #1 is.

I don't remember seeing a live data option. Its a pretty basic reader. I will look again tomorrow. Its amazing all whats going on in these newer cars. Still air fuel and spark but not like I learned it.
Thanks again
Thanks again

No live data function. Do you suspect the crank sensor again? I can remove it and bench check it if you tell me how.
I watched a video on checking the crank sensor. It said 2K ohms I read 700. It did seem to create an AC voltage when I waved a knife past it.

We tried everything. First we sprayed the starter fluid in the air cleaner, nothing.We installed a new crank sensor, nothing.We put in a new ICM, nothing.Checked all the fuses and moved the similar relays around, jumped the battery, Nothing.
Both times the problems started with a full tank of gas. Fill up #1 started the miss. Fill up #2 with premium, because we thought we got bad gas, that's when it totally died.
The engine cranks good. You can hear it turning and see the engine move so I say the chain is connected. It ran great right before the miss started and was still running strong with a miss when it died. We are lost.
Might have to bite the bullet and bring it to a shop.

Have you removed the spark plugs and checked the compression yet? I bought an L200 with a stretched chain and low enough compression to not start and run. It cranked like it had good compression so until I checked with a gauge I dismissed that as a possibility.
