4.0 Stalling
Hello!
I've had a weird stalling issue twice this month, coincidentally at the same intersection a few weeks apart.
So, the first time, I came to a stop and the car stalled, turned it back on and the transmission warning light came on for a few kilometres. That was it, no further problems or strange occurrences for 3 weeks.
Until yesterday. Same situation, I come to a stop. Car stalls. I try to start it but it wont fire up. Cranks just fine. Unplugged and replugged a few sensors. Nothing. CPS was also ok since it showed a few RPM when cranking. I then turned off the radio and so on to have a listen. And there it was, the fuel pump didn't run. Changed the fuel pump relais with the horn relais and the car came back to life.
The horn still works with fuel pump relais installed.
When I came home I tried putting the correct relais in their spot and to my surprise the car works.
How? Was the relais switch just a coincidence and the problem could be something else?
What are your suggestions?
Thanks in advance.

I was thinking that might be the issue too. Thats a "take the tank out" issue which is no fun at all. Definitely do your research there. There are several threads describing removing the hose clips underneath and taking care with the pump housing itself, and the filler neck seal, both these being NLA parts. I had the collapsed tank syndrome and have been "fortunate" enough to remove 3 tanks but only have to install one.
