ISF stumbles, stalls, then stalls immediately after starting.
This has already been solved but I thought I'd post it in case someone else experiences it.
As the title stated and the car never threw a code. Everything was pointing to fuel related as most other issues are monitored by the ECU. Stuck on the side of the road for about two hours I started diagnosing what I could with limited tools and support.
Last resort I unplugged MAF. Car started on the second attempt (most cars will stall first time with maf unplugged) I limped it home to take the MAF out. I found a dandelion seed had snuck past the filter and was stuck on the maf elements. Cleared my CEL (from the unplugged maf) and all normal.
I found it odd because the ecu didn't report an issue. Anyways, maybe this will help someone down the road.
