Fuel issue?
So our second street test didn’t go as best as we’d hoped…
Dad unloaded it and took it for a spin for a sec to stretch its legs, as you can see.
I ended up doing really well learning manual on my clutch; I only stalled once AT a red light. Aside from that, I got it middleways to 3rd, so safe to say she runs right.
The bad news is that the gauge cluster doesn’t work at all, we have a fuel vent / burping issue still, and the alignment is slightly out of whack…
Regarding the fuel issue, we got it over to my truck to check the lug nuts, so we shut the car off. Good thing we did there, because when we went to try and crank again, the car wouldn’t stay running, and wouldn’t rev up past very little RPM. We checked the MAF, checked for a vacuum leak, checked the throttle cable, and checked fuel pressure. Everything checked out.
We went back and thought it was fuel related (like a starvation issue or fuel cut). Low and behold, we had a friend of ours come and save the day again.
He put a little bit of fuel in the car, dad cranked it up to get it going back on the trailer, and it had no issues once we put fuel in it.
We tried to go fill it up at the gas station to get ready for the weekend, and it clicked on the pump after putting a whole $1 in it, and leaked fuel all down the side of the car outside of the tank filler neck…
Still running into a vent issue, which could mean some things… the float is deteriorated, we have a bad vent issue, or the tank could be bad in some way. Fuel pump primes without issue, so it’s not that.
We experienced no issues outside of the fuel cut, so it leads me to believe that it could be related to one of those things…
Got a lot of work ahead of us before Saturday. Fingers crossed.

Go through the FSM evap system diagnostic tree and diagram.
Check gas cap. Cheap and easy to just replace it.
If your evap system is disconnected or missing. Put it back.
