86 toyota 4runner wont stay running

I don't know where any relay is.

Found the relay next to fuse box but how do you know if that's working

Got it Engine stalls. One of the first symptoms of an issue with the fuel pump relay is an engine that suddenly stalls. ... Engine does not start. Another symptom of a faulty fuel pump relay is an engine that does not start. ... No noise from the fuel pump. I wondered why I stopped hearing my fuel pump buzzing. Lol

Thank you from Concord Nc.

I hope it's the round one. It was in the fuel relay spot I seen some online that are square.

Marked M4

Question what if my injector relay is so hot is it bad or just not working . And fuel pump relay is not hot.

Thank for getting back. Sorry to hear about your surgery. Your right the relay is round and it does get very hot. The fuel relay does not get hot. . I wouldn't know we're to even look for a short in a wire to the injector. . but the fuel pump is only month or 2 old.

Ok will do ty I'll keep you posted thank you hope you feel better and virus safe

You were right my # 1 spark plug wire. The shortest one . it was bad . everytime I'd hit a bump in the road it must have moved it a little causeing the truck to hit and miss.

Wow what a huge difference driving now. Way better

Ok question my 86 - 4runner vibrates when I give it gas to go at a speed about 40 and keeps vibrating if I put clutch in and go to 4th or third. It will stop but sometimes if ongoing about 45 I'll hit the gas pedal for a sec. And the vibr8 stops till I give it gas again . any ideas.

Would it do that even coasting then if put in in gear it will stop but as soon as I push the gas pedal it goes right to vibrate . . . it would vibrate even 25 mph coming to a stop I shift to 3rd. And it stops but if. I tape the gas pedal it starts again

Ok thank you
