FRS won't start - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Eazy-V · 04-28-2022, 02:09 AM

My FRS has been parked in an underground parking lot for about 4 months due to winter/cold weather and was just attempting to start the car for the first time for spring/summer season, but the car doesn't start now.

I've never had this issue before and seemed to happened out of nowhere. I made sure my battery is charged and even tried a portable jump starter, but it keeps cranking and doesn't fire up.

Only different thing I noticed (could be just bad memory) is that the fuel pump prime doesn't seem to be a loud as before (running Walbro 485), but does make a sound when I put the key into the ON position.

If there is an issue with the Fuel Pump then should I be getting DTC codes? Also, I'm running an EcuTek tune for years, would EcuTek logs show fuel pressure from the the fuel pump? Also, any suggestions would be appreciated.

You might have someone spray some starter fluid in the intake as you turn the engine over.

Well, hell, it used to work, back in the day -

Yeah, I might have to grab a can of that and see what happens.

I'm not sure if a datalog will show anything useful, but I'll try to grab a log during cranking.

It looks like my battery is not good, but I used a jump starter and attached the logs, so would the logs indicated fuel system/pump is working?

I also have this log which was just a few minutes before and I noticed the variable "fuel quantity total I" goes from 0 to about 71, so what would that represent?

buy new battery and test it out

Eazy-V · 05-01-2022, 02:36 AM

Tried new battery and still only cranks, I'm guess it's a fueling issue and added a new datalog:

One variable on the graph is "fuel quantity total I" which shoots to 70.56, so not sure what that means and if that's normal?

Got it resolved, found that the inline fuse on my Deatschwerks fuel pump hardwire kit was completely melted

OK so now the question is why did it melt?

Where is this inline fuse you speak of? It's not part of the Deatschwerks 9-1010 fuel pump install kit for the Walbro 485 pump I hope...
